    What Is Involved in Pig Iron Production? (with pictures)

    Iron ore is combined with charcoal in a blast furnace to create pig iron. The process of pig iron production involves the combination of iron ore, charcoal, and an intermediary material known as a flux inside a blast furnace. As the materials combine with intense heat, much of the iron ore melts, creating a superheated, liquid form

    Oct 30, 2018 Production of Pig Iron by Using the Romelt Process. In the iron and steel industry in the world there are currently two types of factories that produce ferrous metals. There are so-called integrated plants, which start from the extraction of iron ore from the mine to the final rolled products. There are also so-called small factories, which were developed greatly during the second half of the

    Key steps of the process are as follows: upper part of the furnace - free moisture is driven off from the burden materials and hydrates and carbonates are disassociated. lower part of the blast furnace shaft - indirect reduction of the iron oxides by carbon monoxide and hydrogen occurs at 700-1,000 C. Bosh area of the furnace where the burden starts to soften and melt - direct reduction of the iron [and other]

    Iron production converts iron ore into pig iron through a process known as smelting.Early on in the history of iron production in the United States, most furnaces used charcoal as fuel; so charcoal production and iron production were often closely linked. In fact Charcoal was the only fuel for iron production until the 1830s when the industry began a slow transition toward the use coal as fuel
