Emerging Technologies for Iron and Steelmaking

The gas exiting the pre-reduction shaft still has a very high energy content, which can be used elsewhere in the steel plant or for electric power generation. Voest Alpine and POSCO jointly continued to develop the original commercialized process, leading to several important modifications including the limited direct reduction and smelting of ore fines 25 .

Some blast furnaces even reach heights of over 70 m and diameters of 15 m. The temperatures of up to 2000 C in the blast furnace require an extremely heat-resistant lining. For this purpose, artificially produced fireclay bricks made of corundum ((Al_2O_3)) are used, which must also have a very high carbon monoxide resistance.

Steelmaking Slag

4/4/2012D. Sichen, in Fundamentals of Metallurgy, 20059.5.1 Slag–metal mixing In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the

Steelmaking and Refining

The formation of slag, which floats on the surface of the molten steel, is an important part of steelmaking. Slag usually consists of metal oxides and acts as a destination for oxidized impurities. It functions as a thermal blanket, stopping excessive heat loss, and helping to reduce erosion of the refractory lining.
