Nature of
the Industry
Faced with international competition and a complex
global market, the United States steel industry responded by modernizing
manufacturing processes to increase productivity. Despite successful efforts to
reduce costs and an improving competitive position, steel manufacturing firms
still face stiff competition (and employment is expected to continue to decline.
However, investment in modern equipment and worker training has transformed the
U.S. steel industry from one of the Nation's most moribund to one of the world's
leaders in worker productivity and lowest cost producer for some types of steel.
Establishments in this industry smelt and refine
metals from iron ore and scrap. The molten metal output is solidified into
semifinished shapes before it is rolled, drawn, and extruded to make sheet, rod,
bar, tubing, and wire.
New investment has sparked fundamental changes in the nature of this industry.
The most significant change is the development of the electric arc furnace (EAF),
sometimes called the “minimill,” which converts scrap metal from many
sources—such as old bridges, refrigerators, and automobiles—into steel. The
term “minimill” originated from the relatively small size of these mills
when they first appeared, compared with traditional integrated mills. Today,
many EAFs or minimills are larger than integrated mills producing steel from raw
materials. The smaller initial capital investment required to start and operate
an EAF has helped drive its growth. Moreover, scrap metal is found in all parts
of the country, so EAFs are not tied as closely to raw material deposits as are
integrated mills and can locate closer to consumers. EAFs now comprise about
half of American steel production and their share is expected to continue to
grow in coming years.
The growth of EAFs comes partly at the expense of integrated mills. Integrated
mills reduce iron ore to molten pig iron in blast furnaces. The iron is then
sent to the oxygen furnace, where it is combined with scrap to make molten
steel. The steel produced by integrated mills generally is considered to be of
higher quality than steel from EAFs but, because more steps are involved in the
production process, it also is more costly. The initial step in the integrated
mill process is to prepare coal for use in a blast furnace by converting it to
coke. Coal is heated in coke ovens to remove impurities and to reduce it to
nearly pure carbon.
At the other end of the steel manufacturing process, semifinished steel from
either EAFs or integrated mills is converted into finished products. Some of the
goods produced in finishing mills are steel wire, pipe, bars, rods, and sheets.
Products also may be coated with chemicals, paints, or other metals that give
the steel desired characteristics for various industries and consumers. Also
involved in steel manufacturing are firms that produce alloys, by adding
materials like silicon and manganese to the steel. Varying the amounts of carbon
and other elements contained in the final product can produce thousands of
different types of steel, each with specific properties suited for a particular
use.
For workers, modernization of integrated and EAF steel mills often has meant
learning new skills to operate sophisticated equipment. Competition also has
resulted in increasing specialization of steel production, as various producers
attempt to capture different niches in the market. With these changes has come a
growing emphasis on flexibility and adaptability for both workers and production
technology. As international and domestic competition continue for U.S. steel
producers, the nature of the industry and the jobs of its workers are expected
to continue to change.
Working
Conditions
Steel mills evoke images of strenuous, hot, and
potentially dangerous work. While many dangerous and difficult jobs remain in
the steel industry, modern equipment and facilities have helped to change this.
The most strenuous tasks were among the first to be automated. For example,
computer-controlled machinery helps to monitor and move iron and steel through
the production processes, reducing the need for heavy labor. In some cases,
workers now monitor and control the equipment from air-conditioned rooms.
Nevertheless, large machinery and molten metal can be hazardous, unless safety
procedures are observed. Hard hats, safety shoes, protective glasses, earplugs,
and protective clothing are required in most production areas.
Cases of occupational injury and illness in the industry were 9.6 per 100
full-time workers in 1999, higher than the 6.3 cases per 100 workers for the
entire private sector and slightly higher than the 9.2 cases per 100 for all
manufacturing.
The expense of plant and machinery and significant production startup costs
force most mills to operate around the clock. Workers averaged 44.7 hours per
week in 2000, and only about 5 percent of workers are employed part time. Night
and weekend shifts are common, as is overtime work during peak production
periods.
Employment
Employment in the steel industry
declined to about 225,000 wage and salary jobs in 2000, less than half its 1980
level. The rate of decline, however, has slowed in recent years. The steel
industry traditionally has been located in the eastern and midwestern regions of
the country, where iron ore, coal, or one of the other natural resources
required for steel are found. Even today, about 47 percent of all steelworkers
are employed in Pennsylvania, Ohio, and Indiana. The growth of EAFs has allowed
steelmaking to spread to virtually all parts of the country, although many firms
find lower cost rural areas the most attractive. Large firms employ most workers
in the steel industry. More than 9 out of 10 work in establishments employing at
least 50 workers, and almost half work in establishments employing 1,000 or more
persons (chart 1).
Occupations
in the Industry
Opportunities exist in a variety of
occupations, but the largest group of workers—45 percent—are employed in
production occupations (table 1). Installation, maintenance, repair, and
construction workers accounted for about 18 percent of jobs; and transportation
and material-moving workers accounted for about 16 percent. About 20 percent of
jobs were in managerial, professional, sales, and administrative support
occupations.
Although the steel making procedure varies with the type of furnace used, the
jobs associated with the various processes are similar. At integrated mills,
production begins when material-moving workers load iron ore, coke, and
limestone into the top of a blast furnace. As the materials are heated, a
chemical reaction frees the iron from other elements in the ore. Metal-refining
furnace operators and tenders, also known as blowers and melters, direct the
overall operation of the furnace to melt and refine metal before casting or to
produce specific types of steel. They gather information on the characteristics
of the raw materials they will use and the type and quality of steel they are
expected to produce. They direct the loading of the furnace with raw materials
and supervise the taking of samples, to ensure that the steel has the desired
qualities. They may also coordinate the loading and melting of raw materials
with the steel molding or casting operation to avoid delays in production.
Generally, either a basic oxygen or an electric arc furnace is used to make
steel. Operators and tenders use controls to tilt the furnace to receive the raw
materials. Once they have righted the furnace, they use levers and buttons to
control the flow of oxygen and other materials into the furnace. During the
production process, assistants routinely take samples to be analyzed. Based on
this analysis, operators determine how much longer they must process the steel
or what materials they must add to meet specifications. Operators also pay close
attention to conditions within the furnace and correct any problems that arise
during the production process.
Traditionally, liquid steel was moved from the furnaces into a ladle from which
it was poured into ingots. Steel producers now use a process known as
“continuous casting” almost exclusively. Continuous casting allows firms to
produce steel ready for the next step in processing directly from liquid steel,
thus eliminating many of the steps involved in pouring and rolling ingots. Metal
pourers and casters tend machines that release the molten steel from the ladle
into water-cooled molds at a controlled rate where it solidifies into
semifinished shapes. These shapes are then cut to desired lengths, as they
emerge from the caster. During this process, operators monitor the flow of raw
steel and the supply of water to the mold.
The “rolling” method shapes most steel processed in steel mills. In this
method, hot steel is squeezed between two cylinders, or “rollers,” which
flatten or shape the steel. Rolling machine setters, operators, and tenders
operate the rolling mills that produce the finished product; the quality of the
product and the speed at which the work is completed depend on the roller’s
skills. Placing the steel and positioning the rollers are very important, for
they control the product’s final shape. Improperly adjusted equipment may
damage the rolling mill or gears.
Extruding and drawing machine setters, operators, and tenders operate equipment
to extrude or draw metal materials into tubes, rods, hoses, wire, bars, or
structural shapes. Cutting, punching, and press machine setters, operators, and
tenders operate machines to saw, cut, shear, slit, punch, crimp, notch, bend, or
straighten metal. Welding, soldering, and brazing workers join metal components
or fill holes, indentations or seams of fabricated metal products. Multiple
machine tool setters, operators, and tenders operate more than one type of
cutting or forming machine tool or robot.
Team assemblers and leaders work as part of a team responsible for assembling an
entire product or component of a product. Team assemblers can perform all tasks
conducted by the team in the assembly process and rotate through all or most of
them rather than being assigned to a specific task on a permanent basis. They
may participate in making management decisions affecting the work. Machinists
operate a variety of machine tools to produce precision parts and instruments.
They may fabricate and modify parts to make or repair machine tools or maintain
industrial machines. Inspectors, testers, sorters, samplers, and weighers check
parts or products for defects, wear, and deviations from specifications.
Millwrights are employed to install and maintain much of the sophisticated
machinery in steel mills. As the technology becomes more advanced, they work
more closely with electricians, who help repair and install electrical equipment
like computer controls for machine tools.
With more sophisticated technology and demands for specialized products,
computer specialists, engineers, and engineering technicians have a significant
role in the steel industry. For example, industrial engineers design, test, and
evaluate integrated systems for managing production including quality control,
inventory control, logistics and material flow, cost analysis, and production
coordination.

Training
& Advancement
Many jobs in steel manufacturing
require only a high school diploma. However, as machinery becomes more complex,
employers increasingly prefer to hire graduates from formal postsecondary
technical and trade schools for highly skilled operating positions.
After production workers are hired,
they receive specific training on the job. New workers entering the production
process as lower skilled operators and maintenance personnel generally assist
more experienced workers, beginning with relatively simple tasks. As workers
acquire experience, they specialize in a particular process and acquire greater
skill in that area. The time required to become a skilled worker depends upon
individual abilities, acquired skills, and available job openings. It generally
takes at least 2 to 5 years, and sometimes longer, to advance to a skilled
position. At times, workers change their specialization to increase their
opportunities for advancement. Workers are continuously trained to perform a
variety of tasks and provide more flexibility to the firm, as company needs
change. Computers have become important, as companies have modernized. Workers
must learn to operate computers and other advanced equipment.
To work as an engineer, scientist, or in some other technical occupations in the
steel industry, a college education is necessary. Many workers in administrative
and managerial occupations have degrees in business or possess a combination of
technical and business degrees. A master’s degree may give an applicant an
advantage in getting hired or help an employee advance. Managers need strong
problem-solving, planning, and supervisory skills.
Job Outlook
Employment in the steel industry is expected to
decline by about 22 percent over the 2000-10 period, primarily due to increased
use of labor-saving technologies and machinery. Other factors affecting
employment in the industry include foreign trade, overall economic conditions,
growth of EAFs, and environmental regulations. Despite the continuing decline in
employment, qualified workers still will be needed to replace workers who retire
or leave the industry. In production occupations, opportunities will be best for
individuals with the technical skills and training to handle technologically
advanced machinery.
Employment levels in coming years will be greatly
affected by the ability of steel makers located in the United States to compete
with imports from abroad. Worker productivity has increased in U.S. firms in
recent years, leaving the domestic steel industry better able to compete with
imports. The unintended consequence of productivity gains and growing foreign
competition has been a glut of steel on the international market. Overcapacity
stemming from increased output and slowing demand for steel has reduced the
market price of steel to all-time lows. Many American steel producers complain
that these low prices are the result of unfair competition from abroad and that
foreign producers subsidize their operations through government intervention.
This “dumping” of steel in the U.S. market puts further pressure on domestic
producers to decrease costs and increase productivity. Efforts currently are
underway to improve trade relations in steel and help provide security for a
historically significant domestic industry. If successful, the most efficient
American firms could take advantage of an increasingly attractive trade market
that will result in export opportunities. It also would hasten the demise of
inefficient plants trying to compete with low-priced imports.
Employment in the steel industry varies with overall economic conditions and the
demand for goods produced with steel. For example, as the automotive industry
produces more cars and light trucks, it will purchase more steel. In this way,
much of the demand for steel is derived from the demand for other products.
Other industries that are significant users of steel include structural metal
products, motor vehicle parts and equipment, and household appliances. As many
of these goods require a large outlay, consumers are more likely to purchase
them in good economic times.
Steel companies, like most businesses, have entered the era of sophisticated
technology. Taking several forms, this technology has improved both product
quality and worker productivity. Computers are essential to most technological
advances in steel production, from production scheduling and machine control to
metallurgical analysis. Computerized systems change the nature of many jobs,
while they eliminate or reduce the demand for others. For example, computers
allow one worker to perform duties that previously took the efforts of several
workers. However, computer-controlled equipment often requires operators to have
greater skills. Hence, workers who are comfortable with computers and other
high-tech equipment—as well as those willing and able to learn—will be more
widely sought after by employers. This automation will contribute to better
opportunities for engineers and other professionals, while causing significant
declines for lower skilled machine operators and inspectors.
Environmental issues also have affected the steel industry. Past decades have
seen technological changes spurred by environmental emission regulations.
Emission standards, under the present Clean Air Act, will likely result in
costly modifications or shutdowns in many coal-processing facilities that employ
a dirty, heavily polluting process. Necessary furnace modifications will require
major investments and increase the overall cost of production for coke-producing
plants. These modifications are, therefore, likely to raise costs in integrated
mills that use coke to produce steel.
The emergence of EAFs is perhaps the most important factor in transforming the
steel industry. This trend will continue in the foreseeable future, as EAFs
dominate the new capacity expected to begin operation in the next few years.
Integrated mills are expected to maintain a major share of the market in higher
grade steel and are also entering areas like residential construction, but EAFs
will continue to account for a larger share of the international steel market.
Growth of EAFs is driven by many factors, including relatively low startup
costs, flexibility, and the ability to locate close to the consumer. This is
especially important in the construction industry. Because the scrap steel they
need to operate is widely available, EAFs have provided job opportunities in the
steel industry in additional geographic areas. However, because they generally
have higher worker productivity, as EAFs capture more of the domestic steel
market, fewer workers will be employed to meet the existing demand for steel
products.
Earnings
Earnings in the steel industry vary by occupation
and experience but are higher than average earnings in private industry. Average
weekly earnings of nonsupervisory production workers in 2000 were $870 in the
steel industry, compared with $597 in all manufacturing and $474 throughout
private industry. Weekly earnings in blast furnaces and steel mills, at $967,
were significantly higher than those in steel pipes and tubes, at $645. Earnings
in selected occupations in steel manufacturing appear in table 2.

Union membership, geographic location, and plant size affect earnings and
benefits of workers. In most firms, earnings or bonuses are linked to output.
Workers receive standard benefits, including health insurance, paid vacation,
and pension plans.
The iron and steel industry traditionally has
been highly unionized. In 2000, 40.3 percent of steel workers were covered by
union contracts, compared with 16.2 percent in durable goods manufacturing and
14.9 percent in all industries. In some instances, companies are closed
shops—that is, workers must belong to the union in order to work there. EAFs,
though, typically are nonunion. The overall decline of employment in traditional
integrated steel mills and the growth of EAFs, together, have caused union
membership to decline in recent years.
