| 摘 要： | 分析了钢中Cr的氧化、氮化反应热力学,试验研究了0.025%～0.045%Cr对900℃退火+750～1 050℃二次退火的0.5 mm无取向硅钢(%:0.001 8C、0.45Si、0.45Mn、0.106P、0.003S、0.001 2N)磁性能的影响。结果表明,钢中含Cr氮化物析出温度为913 K,在热轧精轧和卷取过程中析出;随钢中Cr含量的增加,钢的晶粒尺寸减少,铁损中的磁滞损耗增加,而涡流损耗变化不大,为保证钢的电磁性能,应控制钢中Cr含量≤0.03%。

| Abstract: | The thermodynamics of oxidizing and nitriding reaction of Cr in steel is analyzed and the effect of 0. 025% - 0. 045% Cr on magnetic properties of 0. 5 mm non-oriented silicon steel (% : 0. 001 8C, 0.45Si, 0.45Mn, 0. 106P, 0. 003S, 0. 001 2N) annealed at 900 ℃ + secondary annealed at 750 ~ 1 050 ℃ is tested and studied. Results show that the precipitation temperature of nitride of Cr in steel is 913 K, i. e. it precipitates during hot finishing rolling and coiling process ； with increasing Cr content in steel, the grain size of steel decreases, for core loss the hysteresis loss increases , while change of vortex loss is little, in order to ensure the magnetic properties of steel, the Cr content in steel should be controlled ≤0. 03%. |
