Primary Steel Making. 109 Kabi Circuit, Deception Bay QLD 4508. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and convert it into high-quality steel.. Why Choose Custom Metal Fabrication For Your Next Project? Hot rolled products are divided into flat products, long products, seamless tubes, and specialty products. "The Making of Iron and Steel," Page 23. 5 Tips to Help You Choose the Right Steel Fabricator. Accessed Jan. 13, 2020. Iron ore, lime, and coke are placed into a blast furnace and melted. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle, they need to be eradicated. There are two main methods for making steel and these are Basic Oxygen Steel making (BOS) and Electric Ark Furnaces (EAF). By using ThoughtCo, you accept our, What You Should Know About Metallurgical Coal, The Properties, Production, and Applications of Tin, Climate Change Facts and Effect on the Economy, An Introduction to Cryogenic Hardening of Metal, Manufacturing Jobs with Examples, Types, and Changes, Properties and Composition of Type 201 Stainless Steel, Trade Wars and their Effect on the Economy and You, Rising Sea Level Effects, Projections, and Solutions, CAS-OB (composition adjustment by sealed argon bubbling with oxygen blowing). Step 2 - Steel making The steel making process is shown in Figure 2. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle. Finally, it's time for manufacturing, fabrication, and finishing. The electric arc furnace melts recycled steel scrap. Terence Bell wrote about commodities investing for The Balance, and has over 10 years experience in the rare earth and minor metal industries. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. Once cooled the metal is then cut into desired lengths depending upon the application eg, slabs for plates, blooms for sections such as beams, and billets for longer products such as wiring or thin pipes. "World Steel Figures in 2019," Page 8. Process involved in manufacturing • Carbonization of COKE • Blast furnace • Basic Oxygen Steel making [BOS] • Electric arc method 3. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle, they need to be eradicated. "Introduction to Steels and Cast Irons," Page 1. Step 2 does exactly this. Interactive Steel Manufacturing Process AIST’s Making, Shaping and Treating of Steel ® Wheel. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. Custom Sheet Metal Fabrication – What Are the Benefits? So there you have it, the entire steel making process in 6 steps! If you’re in need of a particular metal part then why not contact Metro Steel. It may be used for beams, billets, slabs or other … The BOS method adds recycled scrap steel to the molten iron in a converter. Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. World Steel Association. Steel is the world's most popular construction material because of its unique combination of durability, workability, and cost. Then, the steel once again passes through the EAF (Electric Arc Furnace) for refining the composition of steel. Smelting Reduction Technologies Coke-oven-Sinter-BF route used by integrated steel plants that produce steel from iron ore. Oxygen is then forced through the liquid (the Bessemer process) to cut the impurities in the molten metal down to 0.5% -1.5%. Next, the strand is cut depending on application—slabs for flat products (plate and strip), blooms for sections (beams), billets for long products (wires), or thin strips..
