Rolling mill and zero adjustment method of the rolling mill

摘要

By been found that they have found that rolling method force is generated in adjustment by kiss roll of conventional, the rolling direction force does not affect the roll thrust force, more the initial pressing position adjustment of the rolling mill of the accuracy invention (reduction It is obtained by allowing the zero adjustment). In other words, the working side of the work roll and the difference between the drive side of the working side of the rolling direction force acting on the chocks of the drive side is in (within ± 5% of the sum of the rolling direction force of the drive side of the working side actually) almost zero By performing the zero point adjustment of the differential pressure leveling the drive side and the working side as, and is based on the fact that it is not affected thrust force may not act on the rolls, pressure zero adjustment with high accuracy can be .
