  • Steelmaking

    Iron production using direct or smelting reduction Processes have also been developed to reduce ores without using coke. These processes are grouped together as either direct reduction or smelting reduction. In the case of direct reduction, no liquid hot metal is produced because the process operates at lower temperatures than in the blast furnace.

  • How we make steel | British Steel

    A hot air blast of temperatures around 1,000°C is injected at the bottom of the furnace through nozzles called tuyeres. As the coke burns, temperatures higher than 2,000°C are reached and this heat creates molten metal (iron). The molten metal collects at the bottom of the furnace and the limestone combines with impurities to form slag.

  • How Cement Is Made

    The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. After quarrying the rock is crushed. This involves several stages. The first crushing reduces the rock to a maximum size of about 6 inches. The rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller.

  • The Steel Manufacturing Process

     · In India, ironworkers developed an iron smelting process that combined the perfect ratio of iron to carbon. Using crucibles, or clay containers, the ironworkers would blend iron and charcoal pieces together in a hightemperature furnace. While cooking, the iron would melt and absorb carbon atoms from the charcoal.

  • HOW A BLAST FURNACE WORKS

    Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from to inches. This ore is either Hematite (Fe 2O 3) or Magnetite (Fe 3O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing. .

     · The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent. The carbon is fed to the blast furnace in the form of coke ( pyrolyzed coal) from the coking plant.
