摘要
结合工业化生产的50A1300牌号无取向硅钢,分析了化学成分、RH精炼脱氧方式、板坯装炉温度以及热轧平整工艺等对磁性能的影响,探讨成品钢磁性能的改善。结果表明,采取改善后,50A1300牌号无取向硅钢的磁性能得到明显改善。2012年,该钢种平均铁损、磁感应强度分别达到5.26 W/kg、1.762 T,能够较好地满足用户市场需求及同行对标需要。
Based on the industrial manufacture of 50A1300 grade non-oriented silicon steel sheets, effects of chemical composition, deoxidization method in RH vacuum refining, charging tempera^re of steel slabs, hot rolling and flattening progress on magnetic properties are analyzed. The optimization methods of magnetic properties of steels are discussed. Results show that the magnetic properties are obviously improved by the adopted measures above. In 2012, the average core loss and the magnetic induction of 50A1300 grade non-oriented silicon steel sheets reached 5.26 W/kg and 1.762 T respectively, and could meet the requirement of marketing better.
