Roughing rolling mill is a machine for rolling steel. Rough rolling is in the middle of heating and intermediate rolling mill, and its function is to process the heated slab by a roughing rolling mill into an intermediate blank that satisfies the finishing requirements (specification, temperature, surface quality, plate type).
Roughing mill rolling of reheated slab: The roughing mill usually consists of one or two roughing stands in which the slab is hot rolled back and forth 5 or 7 times repeatedly to reach the minimum thickness requirement. The roughing mill also contains edger rolls that are used to roll the edge of slab and center it.
