Influence Factors of the Vertical Rigidity of Hot Strip Mill
The rigidity of a rolling mill is an inherent characteristic parameter of the mill itself,and it is also related to the rolling conditions during the actual rolling process.Considering the characteristics of the rolling mill rigidity affected by rolling conditions in actual rolling process,this study analyzes the influ-ence mechanisms of strip width and rolling speed on the rigidity of the rolling mill,and derives the rela-tionship between strip width,rolling speed,and the rigidity of the rolling mill.Furthermore,the study u-tilizes the correlation analysis method,MIC,to analyze the influence of some equipment parameters on the rigidity of the rolling mill.It is found that the roll diameter of the support roll and the step pad height have a significant impact on the rigidity of the rolling mill,where the influence of the roll diameter of the work roll is approximately 80%of that of the support roll.Additionally,the effect of wear on the work roll on the rigidity of the rolling mill is relatively small.These findings are of great significance for the compensa-tion and correction of the rolling mill rigidity in the secondary control model of the hot strip mill.
