Important aspects of Rolling of Hot Rolled Coil in Hot Strip Mill
The range of HSMs for the rolling of hot rolled coils has undergone significant changes in the last few decades with minimum thickness of the hot rolled strips has been decreased from 1.8 mm to 2 mm to 0.8 mm to 1.2 mm. The strips of such thickness were earlier produced only in the cold rolling mills.With a view to the wide size range of the hot rolled strip thicknesses from 1.5 mm to 20 mm, width from 750 mm to 2200 mm as well as the conditions and costs for maintenance of the coiler station, a three roll or a four roll coiler offers a large number of practical benefits.
