Pig Iron Process Diagram

In the electric steel process, the sponge iron obtained from the direct reduced iron process is used for crude steel making. In general, scrap is also added to this process as well as pig iron from the blast furnace process. These components are then mixed in a special oven.

Producers of titanium dioxide slag in Canada, South Africa, and Norway smelt ilmenite, a weakly magnetic ore of titanium dioxide and iron oxide (FeTiO 3) in electric furnaces at temperatures ranging from 1650 -1700° C, using either coal or another carbonaceous material as reductant.Titanium dioxide slag is the principal product, with pig iron being a co-product.

The raw materials needed for the production of pig-iron are iron ore and coke. Depending on the type of impurities in the iron different fluxes are added, for example limestone (for siliceous iron ore) or feldspar (for calcareous iron ore).

These gasses drive off the oxygen contained in iron ore, producing metallic iron. Unlike pig iron (the product of a BF), the result of the DRI process, sponge iron, which still retains silica that must be removed in the EAF [26]. A combination of recycled scrap, sponge iron, and hot-briquetted iron (compacted form of DRI) is first loaded into ...

The haematite is widely used for the production of pig iron. Since pyrite contains only 30 to 40% iron, therefore it is not used for manufacturing pig iron.
