  • running dri tunnel kiln plant - tablehyme.co.za

    DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines.

  • Production of Sponge Iron through Tunnel Kiln Process.docx...

    Tunnel Kiln Process Hoganas has developed a process in 1908, which uses coal as a reductant. The carbothermic reduction of iron ore takes place in horizontal tunnel kiln. Reduction mix, consisting of coal or coke fines of the size 3 mm or below, anthracite, and limestone, is charged with iron ore in ceramic muffles/saggers.


  • Reduction of iron ore briquettes into DRI in the tunnel kiln process ...

    Reduction of iron ore briquettes into DRI in the tunnel kiln process We offer third generation tunnel kiln process from China, to convert soft iron ore lumps or briquetted iron ore fines into Direct Reduced Iron (DRI). DRI or sponge iron is a high-quality metallic product and used as a feed-stock in the induction furnace / electric arc furnace.


  • Tunnel Kiln Coal Based DRI Plant - Electrotherm

    Product Description. Tunnel Kiln Coal Based DRI Plant. Tunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 99.9% purity. When iron ore is mined or processed (in a crusher), lots of fines are generated. Quantity of fines generation is a function of the quality of ore i.e. whether it is hard or soft.
