Converting is a type of metallurgical smelting that includes several processes; the most commercially important form is the treatment of molten metal sulfides to produce crude metal and slag, as in the case of copper and nickel converting. A nowuncommon form is batch treatment of pig iron to produce steel by the Bessemer process. The vessel used was called the Bessemer converter.
Aug 01, 2015· The role played by the slag in the oxygen converter steelmaking process is very important. Lime is critical to steelmaking. The science of how lime interact with the various components formed during the steelmaking is the basis for understanding the old phrase ''Make the slag and the steel will make itself''.
Converter steelmaking is the main step in orebased steel production using blast furnace hot metal and steel scrap as basic raw materials. About 70% of steel is nowadays produced via different variants of basic oxygen converters. The converter process was developed in the middle of the nineteenth century using bottomblown air for oxidation.
