Continuous Casting (“CC”)
Method of casting steel directly from the furnace to a certain mold, either steel slab or billet. The steel in the furnace is casted into pots which are placed on a distributor, which in turn, is located on the top of the continuous casting.

At the end of the continuous casting, a guillotine cuts the continuous flow forming billets or slabs.
