【摘要】：针对某冷轧厂无取向硅钢生产中出现的纵向厚度不符、带钢全长纵向厚度高精度命中率偏低的问题,对该厂带钢纵向厚度控制的主要环节进行分析。通过工业过程数据分析和理论计算,研究了测厚仪设定参数和冷轧工艺参数对无取向硅钢纵向厚度精度的影响,并优化相关参数,最终提出提升冷轧无取向硅钢纵向厚度精度的技术方案。该技术方案应用于现场生产后,消除了生产初期批量出现的硅钢厚度不符的现象,无取向硅钢全长纵向厚度偏差5μm以内的比例由方案应用前的85%上升到98%,3μm以内的比例达到90%。
[Abstract]:Aiming at the problem that the longitudinal thickness is not consistent in the production of non-oriented silicon steel and the high precision hit ratio of full-length longitudinal thickness of strip steel is low in a cold rolling plant, The main links of longitudinal thickness control of strip steel in this factory are analyzed. Through the analysis of industrial process data and theoretical calculation, the effects of thickness gauge setting parameters and cold rolling process parameters on the longitudinal thickness accuracy of non-oriented silicon steel are studied. Finally, the technical scheme of improving the longitudinal thickness accuracy of cold rolled non-oriented silicon steel is put forward, which is applied to the field production and eliminates the phenomenon that the thickness of silicon steel does not match in the initial batch production. The ratio of longitudinal thickness deviation of non-oriented silicon steel within 5 渭 m increased from 85% before application to within 98 渭 m.
