An integrated mill is capable of the entire steel production process, from the melting of raw materials all the way through processing a finished coil. Regarded as the traditional, purest way of making steel, integrated mills utilize a Basic Oxygen Furnace (BOF) to melt iron ore, coke, limestone, and scrap into molten steel.

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 ...

The integrated steelmaking process begins in some integrated mills by producing "coke" from bituminous coal in what is called a coke oven. Coke. is a solid carbonaceous residue derived from lowash, lowsulfur bituminous coal. The volatile constituents of the coal (including water, coalgas and coaltar) are driven off by baking in an ...

The integrated steel mill analyzed in Section 4 is used here as the Reference process. In this process, casting requires only a small amount of heat for preheating of the ladle and electricity for, for example, drive power and crane handling. Shaping requires the most energy, particularly the reheating furnace ( GJ/trs).

Overall, process heat recovery saves approximately GJ per tonne of hot rolled steel (GJ/t hrs), integrated heat recovery with conventional heat exchange could save hrs, and an alternative heat exchange that also recovers energy from hot steel could save hrs.

Various designs of the casters shape the steel as it continues to flow. The steel is shaped into semifinished products such as blooms, billets, or slabs. Another finishing route, which is not used as frequently as continuous casting, is ingot casting. Molten steel is poured from the ladle into an ingot mold, where it cools and begins to solidify.
