3B(2) Deformation of Rolling Mill

3B(2) Deformation of Rolling Mill

The ratio of the rolling force to the amount of vertical deformation of the whole rolling mill, including the deformation of the roll, screwdown device, and housing, is called the mill modulus. The mill modulus is 5001,000 ton/mm for plate rolling mills and 400600 ton/mm for cold rolling mills.
