METHOD FOR ADJUSTING THE ROLL GAP OF SINGLE STAND REVERSING MILL

摘要

The present invention is one stand plate with reversible rolling mill parts that occur during the process of transformation, the role in consideration of the influence of the thermal crown and wear for its object to provide a method which allows to set automatically a precise rolgaep. ; 1 rolgaep set of reversible rolling mill stand according to the invention for this method is, current and rolgaep (RG), the rolling load, the width of the strip and entry and exit side thickness, mill housing deformation amount is calculated using the process conditions, such as vendor-force value ( _h ) and the roll deformation ( _RD ) and subjected to the following equation to calculate the outlet strip thickness estimates (h), and the expected and actual compares the measured strip thickness and the outlet from the difference between the predicted value and the measured value of the constant but the decision, the strip is to calculate the difference between the predicted value and the new measured value each time it passes through the rolling rolls compensating for the difference in constant , and is characterized in that the basis of this reset rolgaep.
