process of iron ore coke and limestone

Sep 24, 2019 · During this process, it softens, then liquefies, and re-solidifies into a hard porous material called "coke". This is not the cola soft drink. Coke is a porous, carbon-rich material used to make steel. The coke is mixed with iron ore and limestone to make molten iron, which is then further treated and heated to make steel

We believes the value of brand, which originates from not only excellent products and solutions, but also considerate pre-sales & after-sales technical services. After the sales, we will also have a 24-hour online after-sales service team to serve you. please be relief, Our service will make you satisfied.

    why usecoke for blast furnace ironmaking not usecoal

    Coke is an important raw material in the smelting process of the blast furnace, accounting for about 45%. Others include pellets, sinter, lump ore, limestone and so on. Regarding coke, some people may have doubts. Coke and coal are all high-heating fuels. Even some anthracites have higher calorific value than coke and are cheaper than coke

    Smelting is a heating process in which the Iron ore is heated along with coke (charcoal) and limestone in a blast furnace. The heating process melts the iron contained in the mixture and eliminates much of the carbon that is contained. Using variations of this process Iron ore is also used as a base to derive pig iron, cast iron and steel
