An intermediate product made by pouring molten steel into moulds of given dimensions. In further processing steps carried out in a cogging mill, the ingots are transformed first to simple shape semi-finished products like blooms or slabs and then fed to hot-rolling mills. Ingot casting is now largely replaced by continuous casting.
Integrated metallurgical process
The process including all stages starting from raw coal and iron ore to rolling finished products at one site.
Interstitial free steel (“IFS”)
A sheet steel product with very low carbon levels used primarily in automotive deep-drawing applications. Interstitial Free Steel’s improved ductility (drawing ability) is made possible by vacuum degassing.
