Rolling method for h-shaped steel
专利汇可以提供Rolling method for h-shaped steel专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain the H-shaped steel having good dimensional accuracy without generating shape defects by subjecting a rough billet to a finish rolling while restraining at least one of the transverse ends of respective flanges and adjusting the inside width size of a web by reduction. CONSTITUTION:The rough billet which has the web and flanges and is subjected to a rough rolling is subjected to the finish rolling to raise the angle of the flanges, to roll down the web height and to roll down the thicknesses of the web and flanges while at least one of the transverse ends of the respective flanges of the rough billet is restrained by a universal rolling mill having a pair of upper and lower variable width horizontal rolls H set at the roll width at which the reduction rate of the inside width of the web is within 4 times the web thickness of the rough billet and a pair of right and left vertical rolls V having the roll gap corresponding to the prescribed web height, by which the inside width size of the web is adjusted by reduction and, therefore, the good H-shaped steel is rolled without generating the shape defects, such as deviation in the center of the web.，下面是Rolling method for h-shaped steel专利的具体信息内容。
