根据兰钢集团公司《六五零中型材改造可行性研究报告》所提出的矫直机工作要求为；可正反转，矫直速度在1．5～5．0m／s之间可调。结合此要求，需对我厂现有矫直机做以下工作。在此矫直速度下计算主电机功率；按计算出的主电机功率校核矫直辊强度。1计算生电机功率首先我们了解
According to the Lanzhou Iron and Steel Group Corporation, “five hundred and fifty midsize transformation feasibility study report” proposed by the leveler work requirements; can be reversed, straightening speed adjustable between 1.5 ~ 5.0m / s. In combination with this requirement, we need to do the following work for our existing straightening machine. The main motor power is calculated at this straightening speed; the straightening roller strength is checked against the calculated main motor power. 1 Calculate raw motor power First, we understand
