专利汇可以提供Rolling reduction control method for continuous caliber rolling mill专利检索,专利查询,专利分析的服务。并且PURPOSE:To reduce the variation in the top and bottom size and oval size by finding the target value at the inlet side of the final stand from the load variation of the upstream stand and by controlling the rolling reduction under taking into consideration the passing time, etc., of the rolling stock. CONSTITUTION:The temp. change of a rolling stock is found by a temp. computing element 26 based on the observation value of a load detector 16 and the temp. variation of the final H4 stand is operated by inputting it into the final stand temp. computing element 26 in H2 (horizontal) stand. The oval size variation at the H4 stand inlet side is operated by inputting this value into a target size correction computing element 30, the roll opening of a V3 (vertical) stand is adjusted based thereupon and the oval size at the H4 stand inlet side is controlled. In this case, an output timing control device 32 delays the output timing by the transfer time of the rolling stock among H2-V3 stands and speeds the output timing by the responding time of a V3 stand rolling reduction control can be performed when the point subjected to a load detection at H2 stand arrives at V3 stand.,下面是Rolling reduction control method for continuous caliber rolling mill专利的具体信息内容。
