12.5 Iron And Steel Production

2015-9-10  The molten iron and slag are removed, or cast, from the furnace periodically. The castingprocess begins with drilling a hole, called the taphole, into the clay-filled iron notch at the base of thehearth. During casting, molten iron flows into runners that lead to transport ladles. Slag also flowsinto the clay-filled iron notch at the base of the hearth. During casting, molten iron flows into runnersthat

Steel Production - American Iron and Steel Institute

The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process.
