Converted cast iron is cast iron used for further processing into steel (unlike foundry cast iron used for the manufacture of cast iron castings ). Got a name that corresponds to the redistribution process for the production of steel from ore in two stages: cast iron is obtained from ore (as a rule, in the process of blast furnace smelting ), and then "converted" into steel. The production process of pig iron arose and became widespread in the second half of the 19th century in Europe [1] .

Description
Iron-containing ore is loaded with coke into a blast furnace , where iron is reduced by carbon from oxides not to the state of steel, but to cast iron, since cast iron has a lower melting point. Further, excess carbon is removed from cast iron by blowing with compressed air or oxygen, and it turns into steel.
The following conversion processes (methods) are distinguished:
- Scream horn
- Puddling
- Bessemerovsky
- Thomasovsky
- Open-hearth
- Oxygen converter
