十二、带钢的断片带钢的断片是指在轧制过程中带钢断开了。共分两种:一种是产生在焊缝处,另一种产生在非焊缝处。其产生原因如下: 1.焊缝质量不佳或太高,见图40,尤其是40～50号钢和合金钢焊缝处更易断片; 2.在轧制薄规格时,压下量调整不当,板形控制不好; Twelve, strip the broken piece of steel is broken in the rolling process strip. There are two types: one is at the weld and the other is at the non-weld. The reason for this is as follows: 1. The weld quality is poor or too high, as shown in Fig. 40, especially for the weld of 40 to 50 steel and alloyed steel. • When the thin specification is rolled, the amount of reduction is improperly adjusted , Shape control is not good;
