无取向硅钢边裂产生原因与改进措施

Reason and Control Measures of Side Crack in Non-oriented Silicon Steel

针对新钢无取向硅钢生产中的边裂缺陷问题,通过对缺陷取样分析以及现场调查,发现硅钢边裂产生的原因主要是侧导板撞击拉裂所致。通过提高控制板坯板形质量,减少板坯在轧制过程中边部的撞击力,边裂缺陷大大减少。

Aiming at the problem of edge crack in the production of non-oriented silicon steel in Xinsteel,it is found that the main reason of it is that the side guide plate is impacted and pull crack through the sampling analysis and on site investigation.The edge crack can be prevented by improving the quality of slab shape and reducing the impact force on the strip edge during rolling.
