对3层高硅电工钢复合板铸坯进行热轧及温轧变形加工后,采用正火、退火两种热处理方式处理,并观察轧制过程中产生的裂纹,研究不同状态下复合板的磁性能。对不同状态下的试样进行扩散退火处理,研究复合板中裂纹变化及其对磁性能的影响。结果表明:不同热处理工艺下合金内部的裂纹尺寸差异明显,裂纹尺寸对复合板的磁性能影响显著,相对于深裂纹,其他因素的影响较小;温轧变形加工后,复合板内层出现有序组织,但该有序组织在合金存在深裂纹的前提下并不能从本质上提高合金的磁性能;扩散退火工艺可以消除复合板内部的浅裂纹及微裂纹,但不能消除尺寸较大的裂纹,故而不能显著提高存在深裂纹的复合板的磁性能。 After hot rolling and warm rolling deformation processing of casting billet for three-layer high silicon electrical steel composite plate, it was normalized and annealed for heat treatment.
