WebBlast furnace slag is a nonmetallic coproduct produced in the process. It consists primarily of silicates, aluminosilicates, and calcium-alumina-silicates. The molten slag, which absorbs much of the sulfur from the charge, comprises about 20 percent by mass of iron production. WebThe main product of the blast furnace is hot metal, which typically consist of about 94% Fe, 4.5% C, 0.5% Si and small amounts of Mn, P, S and other metals. The temperature of the tapped hot metal is usually between 1400°C and 1500°C. Other main outputs from the process are slag and top gas. labview simulate waveform
