Slag cement, originally known as granulated blastfurnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag. The iron is used to produce steel, and the molten slag is ...

What is Slag? There are two distinct types of slag produced at the Blupe Steel Port Kembla Site; Blast Furnace Slag and Steel Furnace (or BOS) Slag. BLAST FURNACE SLAG. Iron is extracted from iron ore in a blast furnace by a process known as reduction. The raw materials iron ore, coke and fluxes are fed into the top of the furnace.

How Steel Is Made. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace. The blast furnace is the first step in producing steel from iron oxides. 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 ...
