高性能取向硅钢生产过程中的节能降耗
从取向硅钢生产路线的选择、工艺技术的改进和生产设备的改造三方面进行了生产取向硅钢的节能降耗技术改造.通过完善多元抑制剂配方生产低温取向硅钢,通过加抛丸的酸洗、带面超声波清洗、改进连续退火炉以及余热循环利用等技术改造,使2012年取向硅钢的产量与未进行技术改造前的2009年相比提高了2.5倍,产品磁性上升了一个半牌号,能耗下降了8.9%,成材率提高了6.4%,生产成本下降了22%,综合效益显著. Energy saving technological transformation was carried out in the production of grain oriented silicon steel from three aspects of the oriented silicon steel production process route selection,technology improvement and equipment renovation.Through the improvement of multiple inhibitor formulations for producing low-temperature grain-oriented silicon steel,and by adding the blasting pickling,the belt surface ultrasonic cleaning,improvement of continuous annealing furnace,waste heat recycling tec...
