Method for rolling shape having flange
专利汇可以提供Method for rolling shape having flange专利检索，专利查询，专利分析的服务。并且PURPOSE:To form a shape which has a large ratio of its flange thickness to its web thickness without generation of rolling web wave by specifying a moving amount and a draft at the time of moving vertical roll of a universal rolling mill in the rolling direction. CONSTITUTION:An H-shape steel is rolled by moving a vertical roll 2a of a universal rolling mill 2 in the rolling direction. In that case, a web elongation amount and a flange elongation amount are equalized to each other by specifying drafts for a web and a flange. Together with that, the axis of the vertical roll 2a is moved in the rolling direction from the axis of a horizontal roll 2b within a range of a distance 2.0 times as long as a difference D between respective roll contact projected lengths l1, l2 of a flange of a stock 1 to be rolled sandwiched between the vertical roll 2a and a side of the horizontal roll 2b and of the web sandwiched between the rolls 2a, 2b. Hence, the stock 1 having a thin web and a large thickness ratio between the flange and web is rolled without generation of rolling web waveforms.，下面是Method for rolling shape having flange专利的具体信息内容。
