Steel manufacturing
Charged alongside scrap in steelmaking to produce a range of industrial steel grades.
HomeProduct categoriesFerrous metals
Pig iron
Crude iron run from the blast furnace and cast into ingots for remelting, carrying the high carbon of that route at 3.80 to 4.20%. Silicon, manganese and the residuals separate it into foundry grades for castings, SG grades for ductile iron and basic grades for steelmaking.
- Grade / purity
- Foundry, SG and basic (steel) grades
- Form
- Ingots
Applications
Cast iron production
Remelted by foundries with silicon to make durable automotive engine blocks and heavy machinery castings.
Electric arc furnaces
Used to dilute the residual impurities carried in recycled scrap during melting.
Global trade feedstock
Cast into easily transportable ingots supplying manufacturing and construction sectors worldwide.
