Steel Manufacturing Process

The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel

Basic Oxygen Furnace Steelmaking. About 67% of the global crude steel total output is through the Basic Oxygen Furnace Steelmaking process and is recognized as the dominant steelmaking technology. In U.S alone the usage figure is 54% and slowly declining due primarily to the advent of the “Greenfield” electric arc furnace (EAF) flat-rolled

5/9/2015· Modern steelmaking process Due to development of science and technology steelmaking process can also be updated, nowadays it can be carried out into three steps. It gives better steel properties and good quality. 1.primary steelmaking 2.secondary steelmaking /ladle metallurgy/post treatment of steel 3.casting process. 15.

Basics of Continuous Casting of Steel - Steel casting process

The whole process is controlled to ensure there is smooth flow of molten steel through tundish. Further, the impurities and slag are filtered in tundish before they move into the mold. The entrance of the mold is filled with inert gases to prevent reaction of molten steel with the gases in the environment like oxygen.

6 Steps of Modern Steelmaking Process | 3MVET

Modern methods, however, are still based the same premise as the Bessemer Process, namely, how to most efficiently use oxygen to lower the carbon content in iron. Modern steelmaking can be broken down into six steps: 1. Ironmaking: In the first step, the raw inputs iron ore, coke, and lime are melted in a blast furnace. The resulting molten iron - also referred to as ''hot metal'' - …

Steps in the Modern Steelmaking Process

21/8/2020· Primary steelmaking has two methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS method adds recycled scrap steel to the molten iron in a converter. At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%.

• Typically converter steelmaking technology allows to tap liquid steel in approximately every 50 to 60 minutes with specified steel chemistry and 500 -1000ppm dissolved oxygen. • Typically oxygen blowing time is independent of converter capacity i.e. O 2 is blown for

How Steel is Made Using the Basic Oxygen Steelmaking Process

Raw Materials Before the steelmaking process can begin, like any good recipe, the proper ingredients are needed. In this case, the ingredients are raw materials and include iron-ore, coke, limestone, and other minor constituents. The following materials are gathered

Steel making process – ArcelorMittal

There are two main processes for producing steel: by means of a blast furnace (= indirect reduction) in coination with a converter, or by means of an electric furnace. In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron. Sponge is an intermediate product, which
