[email protected]Pig iron is anintermediate product obtained during the smelting of iron ore using high-carbon fuel, such ascoke,charcoal or anthracite. In addition to iron, pig iron consists of varying amounts of phosphorus, sulfur, manganese, silicon, and carbon. Its high carbon content makes it brittle and, hence, it is used for very limited applications.

Dec 04, 2020· The process of pig iron productioninvolves the combination of iron ore,charcoal, and anintermediary material known as a flux inside a blast furnace. As the materials combine with intense heat, much of the iron ore melts, creating a superheated, liquid form.
Puddlingprocess, Method of convertingpig ironinto wroughtironby subjecting it to heat and frequent stirring in a furnace in the presence of oxidizing substances (see oxidation-reduction). Invented by Henry Cort in 1784 (superseding the fineryprocess), it was the first method that allowed wroughtironto be produced on a large scale.

Pig iron is produced in the blast furnace sector. The raw materials used include ore, sinter, coke, lime and various aggregates. To ensure that the production process maintains a high and stable level of quality, these materials have to be metered precisely and supplied to the blast furnace in batches. Teamwork. Process-controlled blast furnace feeding
In1879 Sidney Gilchrist Thomas and Percy Gilchrist adapted the Bessemer converter for use with phosphoric pig iron; as a result, the basic Bessemer, or Thomas, process was widely adopted on the continent of Europe, where high-phosphorus iron ores were abundant. For about 100 years, the open-hearth and Bessemer-based processes were jointly responsible for most of the steel that was made, …
The pig iron is then processed in a converter in order to obtain steel - unlike alumina and copper blister which are electrolytically refined. Processing the ore into pig iron takes place in a blast furnace; this type of furnace has been greatly improved since the nineteenth century although its …
