scrap is used in blast furnaces

Steelmaking

Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron (DRI) in an electric arc furnace Secondary steelmaking involves refining of the crude steel before casting and the various operations are normally carried out in ladlUse of a blast furnace reduced the iron ore, and methods like puddling, the Bessemer process, the open-hearth furnace, and the basic oxygen process were used to manipulate the carbon and oxygen reactions to their advantage Scrap steel could also be incorporated such as seen in an electric arc furnace Module Objectives.

Steel Scrap

In BOF steelmaking, about 75% of iron comes from the hot metal produced by blast furnace process, the remaining 25% of the raw materials is steel scrap EAF process uses steel scrap in general, however, in some plants significant share of direct reduced iron (DRI) is usedThe blast furnace and converter may be omitted from the process if average copper content of the scrap being used is greater than about 90 percent The process used by 1 U S facility involves the use of a patented top-blown rotary converter in lieu of the blast, converting, and reverberatory furnaces and the electrolytic refining process.
