提高钢材轧制成材率是降低成本,提高经济效益的有效手段,而钢锭形状与轧制成材率有着重要的关系。许多企业多年来沿袭采用的上小、下大,平底直方锭形,在轧制过程中会产生鱼尾状不均匀延伸变形,使钢坯两头产生凹形中空,必须切除造成浪费。根据轧制压下规程合理设计锭形减少切头、切尾率,不失为目前提高锭——坯成材率的好办法。 Improve the rolling rate of steel rolling is an effective way to reduce costs and improve economic efficiency, and the ingot shape and rolling rate of success has an important relationship. Many enterprises follow the adoption of the small, large, flat bottom square bar shape, in the rolling process will produce non-uniform extension of the fish tail deformation, hollow billet to produce a hollow, must be removed resulting in waste. According to the rules of rolling reduction reasonable design of ingot to reduce the cutting head, tailing rate, after all, is now a good way to improve ingot - billet rate.
