WhatsApp: +86 18838072829All steel is made using raw iron. As previously mentioned, steel is characterized by the presence of iron and carbon. The ratio of these two elements varies depending on the specific type of steel being made. With that said, most types of steel contain about 1% carbon and 97% iron, with the remaining 2% consisting of trace elements and ...
WhatsApp: +86 18838072829The raw materials for producing molten iron are iron ore, coking coal and fluxes (materials that help the chemical process) mainly limestone. The hot air blast to the furnace burns the coke and maintains the very high temperatures that are needed to reduce the ore to iron. The reaction between air and the fuel generates carbon monoxide.
WhatsApp: +86 18838072829This concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast ...
