无取向硅钢特别是中牌号以上的无取向硅钢,随着含硅量的提高,常温下塑性较差,冷轧过程中轧制力明显提高,如果存在原料质量问题,极易发生断带事故,影响硅钢冷轧过程的成材率和生产效率。通过优化冷轧工艺参数,可提高冷轧稳定性。生产中通过合理分配冷轧各道次压下量和轧制速度,保证了轧制过程的稳定,很大程度减少了冷轧断带事故的发生。 Non-oriented silicon steel, especially non-oriented silicon steel in the grade above, with the silicon content increased, poor plasticity at room temperature, rolling force during the rolling significantly increased, if there is raw material quality problems, prone to broken accident, Affect the silicon steel cold rolling process of the yield and production efficiency. By optimizing the cold rolling process parameters, cold rolling stability can be improved. In the process of production, reasonable distribution of the rolling reduction and rolling speed of each pass ensures the stability of the rolling process and greatly reduces the occurrence of cold rolling and belt breakage.
