For the new Qin alloy material and Qin alloy sheet production process because of its high mechanical properties at high temperatures,high hardness,and the material is not easily deformable,it often cuases the work roll to be abnormally damaged.

For different processing materials,unequal fire times,the process system strictly stipulates its operation method,but for the new Qin alloy material and the new process of producing alloy plate,it has high mechanical properties at high temperature and high hardness,the material is not easy to be plastically deformed etc.and the work roll is often abnormally destroyed,the most prominent failure mode is roll neck twisting and roll surface printing.
