在热轧周期轧机上生产的无缝钢管,其周期头重量的计算无论对轧制表的编制或是对切头率的控制都有直接的关系。长期以来,周期头重量的计算一般采用了两种方法。一种方法是估计法,即是以钢锭重量决定周期头的重量,一般情况是周期头占钢锭重量的8—10％。这种方法只适用于一定的工艺状况,一旦工艺条件改变,例如轧制同种钢管采用不同锭重或同
The production of seamless steel pipe in the hot rolling mill cycle, the calculation of the weight of the cycle head either rolling table preparation or cutting head rate control has a direct relationship. For a long time, two methods were generally used to calculate the weight of the periodic head. One method is to estimate the method, which is based on the weight of the steel ingot to determine the weight of the first cycle, the general situation is the head of the cycle accounted for 8-10% of the weight of the ingot. This method is only applicable to a certain process conditions, once the process conditions change, such as rolling the same type of pipe with different spindle weights or the same
