实验室模拟CSP流程生产了添加铈元素的无取向电工钢,研究了0~0.015%Ce含量对3.0%Si无取向电工钢成品组织、织构、析出物和磁性能的影响。结果表明,适量的Ce能使钢中夹杂物聚集粗化,成品退火后,再结晶晶粒尺寸变大,{100}和{110}织构增多,{111}织构减少。本次实验条件下,3.0%Si无取向电工钢最佳Ce含量为0.0062%,此Ce含量下成品的铁损P15/50为2.75 W·kg~(-1),磁感B50为1.728 T。
Laboratory simulation CSP process produced cerium-added non-oriented electrical steel and studied the effect of 0-0.015% Ce content on the microstructure, textures, precipitates and magnetic properties of 3.0% Si non-oriented electrical steel products. The results show that proper amount of Ce can aggregate and coarsen the inclusions in the steel. After the finished product is annealed, the recrystallized grain size becomes larger and the texture of {100} and {110} increases and the texture of {111} decreases. Under this experimental condition, the optimal Ce content of the 3.0% Si non-oriented electrical steel is 0.0062%, and the iron loss P15 / 50 of the finished Ce content is 2.75 W · kg -1 and the B50 is 1.728 T.
