This paper introduced the techniques improving of the finish mill,such as the introduction of finish mill guide settings and cooling water system,the adjustment of ladder mat and load cell apparatus,bends controlling of work rolls,hydraulic AGC controlling,as well as the technology improving to the tip cap transducer.

This paper introduces force and energy on the medium and heavy plate leveller bending roll device, and when the bending roller hydraulic cylinder contraction and promotes, parts strength could relate has carried on the analysis.
