Basics of Continuous Casting of Steel Steel casting process

Continuous casting, also known as strand casting, is the process where a metal is heated until it liquefies. The molten metal is then allowed to solidify until it becomes a semi-finished slab that is later rolled in the finishing mill. It is used to cast metals of uninterrupted lengths.

2. These pieces are then fed into rotating roll mills and ball mills which pound and grind the ore into finer particles. 3. After crushing and milling, the valuable iron ore particles can be separated from the waste, using magnetic separators. Strong magnets pull the iron ore particles away from the rest of the powder as the separator rotates. 4.
