FAQ's

1. What are the three main ingredients used while manufacturing pig iron?

The three primary ingredients to be placed in the blast furnace are iron ore, carbon, and limestone. As pig iron has a lot of carbon content, it makes pig iron very brittle and not useful directly as a material except for limited applications.

2. What is the purpose of pig iron?

Pig iron is used for steel making, foundries, alloy making, automotive castings, and other iron-based castings. It is the principal component of the charge makeup used by high-quality ferrous foundries and steel mills. For more details, click here.
