The Basic Processes in Steel Manufacturing

• 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.

9

• 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.
