Combined Setting Technology of the Bending Roll in Five Stands 4-High Reduction Cold Mill

Abstract

On the foundation of taking equipment and production technology into consideration,we present a set of combined setting technology of the parameter of the strip suit to cold reduction mill of roll four and framework five。Then the parameter of the strip was controlled combined and coordinated of framework 1-5. On the one hand,it ensures the function of the force of the bending roll not cancel out mutually,and enhances the controlled effect of the force of the bending roll in the strip,on the other hand, there will not be new extra and partial shape wave under the complex effect of the force of the bending roll.Meanwhile there will not be the problem that the force of the bending roll in some parts get too high even overall loading while the other parts get get too low in the setting procedure.While improving the lifespan of the fluid cylinder, the adjusting rest of the force of the bending roll get increased. While the related technology has been adopted by field engineering, we have achieved excellent result, and there is the value for more expanding.
