1975/10/14· In the conventional basic oxygen steel making process, an overhead water-cooled lance is employed in the delivery of high pressure oxygen to the steel bath. The strong oxygen jet impacts on the molten steel bath which is covered by a layer of slag, causing a considerable amount of splashing with the molten particles of steel and slag flying in the free-board of the furnace.

Abstract: A promising option for long-term storage of CO 2 is to fix CO 2 by industrial solid wastes, such as basic oxygen furnace (BOF) steelmaking slag. It is advantage to use BOF steelmaking slag to fix CO 2, such as large volume of BOF steelmaking slag, low price of raw materials, close to the CO 2 emission sources, and no secondary pollution.

Basic oxygen furnace slag (BOF slag) is an unavoidable by-product of steelmaking process of basic oxygen furnace. The main chemical constituents of BOF slag are CaO, FeO, Al 2 O 3 , SiO 2 and MgO. Due to its high metallic value (FeO: 16-20%) and lime content (CaO: 45-50%), it is possible to use in iron making and steelmaking process to replace lime and recover iron and CaO.
