2020-5-213 Sponge Iron Process As the name implies the spongy iron is obtained by the reduction of lumpy iron ore or iron ore pellets from the oxide form into the metallic state. The iron content of the product so obtained varies from 90 to 94 and the balance represents the traces of gangue and residual iron oxide

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94 iron and 3-5 carbon with smaller amounts of other elements. Pig iron has only limited uses and most of this iron goes on to a steel mill where it is converted into

2020-5-24Description. Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke usually with limestone as a flux. Charcoal and anthracite have also been used as fuel. Pig iron has a very high carbon content typically 3.54.5 which makes it very brittle and not useful directly as a material except for limited applications

1987-6-16A process for the production of pig iron from iron ore is disclosed. The pig iron is firstly converted to sponge iron in a direct reduction shaft furnace 1 and then the sponge iron is converted to pig iron in a melt-down gasifier 2. The shaft furnace and melt-down gasifier are interconnected by means of downcomers 6

Cast iron begins its life as pig iron which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron and the iron once melted is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape
