Few Benefits of the Steel Industry
                     The Basic Processes in 
Steel Manufacturing
USS UPI
❏ Learn about the basic processes used in Steel Manufacturing. 
From basic oxygen furnaces to electric arc furnaces, learn about 
the importance of recycling materials in the production of steel. 
After you've learned about the basics, read on to learn more about 
the Electric arc furnace and the Mechanical cutting processes. 
❏ Learn how steel is manufactured and how it differs from other 
metals. Listed below are some of the most important steps in 
Steel Manufacturing. If you have any questions, don't hesitate to 
ask!
Basic Oxygen Furnace Process
❏ The basic oxygen furnace is the leading Manufacturing Steel technology. 
More than half of all steel in the world is made using this process. It uses 
carbon and pig iron to create steel and combines them with pure oxygen. A 
slag that's blown into the melt helps remove impurities that would 
otherwise remain in the finished steel. In addition to the oxygen blown into 
the melt, this process produces low-carbon steel.
❏ The basic oxygen furnace has a three-part structure: a barrel-shaped vessel, 
a top-blown burner, and a bottom-blown one. A top-blown basic oxygen 
furnace has a water-cooled oxygen source and is typically equipped with a 
refractory lining. The pressure of the oxygen is usually between 150 and 
200 psi, with an average lifetime of about 400 heats for a refractory lance.
Electric arc Furnace Process
❏ The electric arc furnace (EAF) is a high-temperature, continuous-
process heating and reducing process used in the steelmaking 
industry. The process is also used for the production of ferroalloys 
and non-ferrous alloys. 
❏ As the temperature of the furnace rises, the electrode tips erode 
and the body of the electrode oxidizes. New electrodes are added 
to the electrode strings, and they are consumed at a rate of about 
three to six kilograms per ton of steel produced.
❏ The Electric Arc Furnace Process is a high-tech steelmaking process 
that uses direct reduced iron as its primary charge material. For this 
process to work, scrap steel must be relatively inexpensive and of 
good quality. In addition to scrap steel, high-quality steel must have 
a minimum residual content of 0.2 percent. 
❏ Since scrap is mostly composed of metal, it does not oxidize during 
the steelmaking process. However, some shops supplement their 
scrap charges with direct reduced iron or cold blast-furnace iron. 
These auxiliary charges, which contain higher carbon content, make 
the electric arc process less attractive.
Mechanical Cutting
❏ While most manufacturers can cut most types of steel by 
mechanical cutting, there are some differences between traditional 
and mechanical cutting. Compared to thermal techniques, 
mechanical cutting is relatively accurate and inexpensive, but it is 
not appropriate for all kinds of materials. Metals prone to melting 
are easier to cut by mechanical methods. 
❏ Similarly, thicker materials are not always easily cut by mechanical 
cutting, and it is more difficult to produce high-quality cuts on thick 
materials. Moreover, waterbed cutting offers advantages in noise 
and fume reduction.
❏ Laser cutting is also an option. It provides cutting to the 
material and a finishing touch to it, while mechanical cutting 
often involves post-machining treatments to ensure that the 
pieces are free of burrs.
❏ Another benefit of using laser cutting is that it produces 
smaller heat-affected zones, which reduces the risk of 
deformation and wear. In addition, laser cutting has parts with 
high accuracy. If you're looking for a high-quality component, 
laser cutting is the way to go.
Recycled Materials used in Steel Production
❏ Recycling steel has several social and environmental benefits. 
Recycled steel creates jobs around the world and reduces the 
country's dependence on foreign steel. This industry employs 
thousands of people worldwide and helps keep the United States 
steel prices low by eliminating the need to import steel from 
abroad. 
❏ Some people are skeptical about the benefits of recycling, as they 
believe that it costs more than buying new products. However, 
recycling saves the environment and helps consumers save money 
on the price of steel.
❏ While the benefits of recycling steel are numerous, the process is 
costly. While steel is one of the most recyclable materials in the 
world, it is not without environmental and financial costs. 
Moreover, steel can be recycled multiple times. 
❏ Stainless steel, the most commonly used steel, does not contain 
iron and is highly magnetized. The majority of steel used in the 
production of consumer products is recycled. In addition, steel is 
also used to make machinery, bridges, and other goods.
Employment Trends in the Industry
❏ While employment in the steel industry has decreased over the past 
three years, the figures show signs of improvement. According to Oxford 
Economics, about 6.1 million people are employed in the industry, while 
another 13 million work in the supply chain. 
❏ As a result, the industry employs a large and skilled workforce and offers 
many opportunities for further education and training. Such education 
and training help improve the quality of work and employee satisfaction. 
To ensure a future in the Steel Services, the industry should promote 
employee education and training.
