     · There are 3 stages in converting iron ore into steel. Stage I Iron Ore, coal and lime stone are put in a blast furnace and melted to extract the metal. This process is called Stage II The iron that is extracted from the furnace is refined. This extract is called steel. Stage III The steel is then cast as billets or slabs. These billets and slabs are used by other Industries as raw material. Question 10

  • IRON AND STEEL - chemguide

    isnt pure oxide - it also contains an assortment of rocky material. This wouldnt melt at the temperature of the furnace, and would eventually clog it up. The limestone is added this slag which melts and runs to the bottom. The heat of the furnace decomposes the

  • The Extraction of Iron - Chemistry LibreTexts

     · This page looks at the use of the Blast Furnace in extraction of from , and the of the raw from the furnace various kinds of steel. Contributors and Attributions. Jim Clark Prof. Robert J. Lancashire The

  • Steelmaking

    Modern processes can be divided into two categories: primary and secondary. Primary steelmaking involves converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steelmaking, or melting scrap steel or direct reduced iron DRI in an electric arc furnace

  • Introduction to Iron ore Pellets and Pelletizing processes

    It is an agglomerating of fines ‘uniformed sized pellets’ which can be charged directly a blast furnace BF or a vertical furnace or rotary kiln normally for the production of direct reduced DRI. The pellets are shown in Fig 1

  • Types of Furnaces | Melting process in a foundry

     · Let’s talk about a few of furnaces. Blast furnaces: These very tall furnaces mostly thought of for metalworking, are injected with pressurized gasses. They’re generally for extracting and some other metals from their ores. The blast furnace can cast ingots of alloys for use in foundries that manufacture other products

  • Extraction of Iron | Metallurgy | Blast Furnace and Reactions

    The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes. Limestone is then added as flux, and it creates the slag. Impurities such as S, Si pass into the and the later can be easily separated to yield pure iron
