以马钢CSP流程生产电工钢特点为基础,模拟了典型高牌号无取向电工钢(50W310)的生产过程,研究了常化温度对典型高牌号无取向电工钢(50W310)的组织、织构和性能的影响。结果表明:经过热轧板常化处理的成品磁性能完全达到国标要求;在实验室研究的热轧板常化温度范围内(900~1 050℃),随着常化温度的升高,热轧板晶粒尺寸逐渐增大;成品晶粒平均尺寸呈先增大后减小的趋势;成品中织构强度变弱,特别是{111}、{112}和{114}等织构明显减弱;成品铁损P15值呈先降低后升高的趋势,磁感B50值单调递增,但增幅较为缓慢。
Based on the characteristics of CSP steel produced in Masteel, the production process of a typical high-grade non-oriented electrical steel (50W310) was simulated. The effects of normalizing temperature on the microstructure, texture and wear resistance of a typical high-grade non-oriented electrical steel (50W310) The impact of performance. The results show that the magnetic properties of finished products after the normalization of the hot-rolled sheet completely meet the requirements of the national standard. In the normalized temperature range (900-1,050 ° C) of the hot-rolled sheet studied in the laboratory, as the normalizing temperature increases, The grain size of rolled sheet increases gradually; the average grain size of finished product first increases and then decreases; the texture strength of the finished product becomes weaker, especially the texture of {111}, {112} and {114} ; Finished product iron loss P15 value first decreased and then increased, magnetic induction B50 value monotonically increasing, but the increase is relatively slow.
