Steel slag. According to the American Society of Testing & Materials, blast furnace slag is a non-metallic compound containing calcium silicates and alum inosilicates and other game elements. It is produced in a blast furnace with iron in the form of melt. Also, according to the definition of this society, steel slag is a non-metallic compound.

Oct 18, 2017 · Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.

Iron slag is a byproduct of iron smelting. When the blast furnace is tapped to release the molten iron, it flows from the furnace with molten slag floating on its upper surface. These two materials are separated using a weir, the molten iron being channeled to a holding vessel and the molten slag to a point where it is to be treated further.

Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, CaCO 3, or dolomite, CaCO 3 ·MgCO 3) are melted together in a blast furnace. When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash ...
