Novel parameter setting integrated system of twenty-high rolling mill control technology

Abstract

The invention provides a novel parameter setting integrated system of a twenty-high rolling mill control technology. The novel parameter setting integrated system of the twenty-high rolling mill control technology comprises a rolling schedule optimization setting module, an elastic roll diameter roll-arranging module, an energetic parameter calculating module and a mill roll system. After the incoming material thickness, the finished product thickness, the strip material width, the maximal rolling force, a maximal rolling reduction ratio and the work roll diameter are input into the rolling schedule optimization setting module, the rolling pass, the total rolling reduction ratio, the rolling reduction ratio of each pass, the rolling force, the forward tension and the backward tension, the rolling speed, the rolling power and the rolling pass outlet thickness are output; and after the roller diameter compensation eccentric distance, the rolling reduction adjusting eccentric distance and the rolling pass outlet thickness are input into the elastic roll diameter roll-arranging module, the work roll diameter, a first middle roll diameter, a second middle roll diameter and the rolling reduction adjusting angle are output. According to the novel parameter setting integrated system of the twenty-high rolling mill control technology, setting of parameters of the rolling mill control technology can be conducted by adopting the incoming material thickness, the finished product thickness and the like without the need of accumulating long-term production data.

Description

technical field [0001] The invention relates to the technical field of sheet and strip rolling for metal processing, and relates to a new type of parameter setting integrated system for the control process of a twenty-high rolling mill. . Background technique [0002] Twenty-high rolling mill is a representative product of precision rolling. During the production process, the rolling process parameters determine the rolling efficiency and quality. The rolling schedule mainly includes the distribution of rolling passes, reduction ratio, rolling force, front and rear tension, etc. Domestic iron and steel enterprises mainly use the empirical method and the energy consumption curve method to formulate the rolling process of different steel grades, and the equipment utilization efficiency is low. [0003] With the continuous progress of production, the wear of the rolls reaches a certain limit and can no longer be used. Roller replacement is required at this time. The twenty...
