For updated plate mills,this paper gives a better idea for the heavy reduction control in the rolling process. That is to keep the reduction amount constant in the front-end and back-end sections of the plate and to adopt tapered rolling with variable reduction in the middle section of the plate. This solution （ already applied for a patent） can not only fully utilize the capacity of the mill motors, but also prevent difficulties in plate biting caused by the conventional heavy reduction solutions with excessive draft. This technical solution has been implemented at the 5 m plate mill plant of Baosteel,and industrial tests have proved the feasibility of it. This paper presents and analyzes the industrial test data and proves that the tapered heavy reduction technology can reduce the number of rolling passes.
