Cast Iron Alloy Production Process

Sep 18, 2015

Cast iron is produced by melting pig iron. Often, this melting is done along with scrap steel and scrap iron. It also involves a number of steps that leads to the removal of undesirable elements (phosphorus and sulfur).

The main purpose of this processing is to reduce carbon and silicon content to the desired levels. Then, the addition of other elements to the melt takes place.

A small blast furnace known as a cupola is used to melt iron.

After melting is complete, the molten iron is removed from the forehearth of the blast furnace.
