专利汇可以提供Method for rolling shape steel专利检索，专利查询，专利分析的服务。并且PURPOSE:To obtain a shape steel having a web of a constant height by performing one or more biting-in and biting-out rollings reducing a web height in the top region of a shape stock and succeedingly performing finish rolling by adjusting a roll gap. CONSTITUTION:A roll gap between vertical rolls V or a finish universal rolling mill is set to a distance A larger than a required web height (l) of an H-shape steel and one or more biting-in and biting-out rollings mainly reducing the top region of a roughly rolled shape stock (h) are performed under guiding by guide rollers 5. Then, a roller gap between the guide rollers 5 and a roll gap between the rolls V are set to the A of the top region web height of the stock (h) and the web height (l) of an H-shape steel to be rolled, respectively; finish rolling is performed by passing the stock (h). Hence, the web of the stock (h) is gradually and rapidly drafted and reduced in the width direction without generation of biting defects or buckling, etc.，下面是Method for rolling shape steel专利的具体信息内容。
