Method for controlling web center deviation of h-shape steel
专利汇可以提供Method for controlling web center deviation of h-shape steel专利检索，专利查询，专利分析的服务。并且PURPOSE:To markedly reduce deviation of the web center by detecting deviations of the web center of a stock to be rolled at positions before and after an edger rolling mill and changing a pass center of the edger mill based on the above detection result, and continuously controlling the deviation of the web center. CONSTITUTION:Continuous rolling of a primary rough universal rolling mill 60 edger rolling mill 61 secondary rough universal rolling mill 62 is performed. Web center deviation amounts detected by a shape measuring instrument 63 between E and UR2, temps. of a stock being rolled at UR2, previously set pass schedule, and information concerned with a material of the stock are inputted to an arithmetic unit 64. The unit 64 calculates a pass center adjusting amount DELTAH of the mill 61 by an equation based on inputted information and sends a signal of the DELTAH to the mill 61. The mill 61 adjusts vertical positions of upper and lower rolls by the adjusting amount DELTAH. Thus, web center deviations over the total length of the stock 2 are reduced and this method is applicable to H-shape steels of various size.，下面是Method for controlling web center deviation of h-shape steel专利的具体信息内容。
