| Abstract: | By studying the microstructure, phase transformation and mechanical properties of the low reheating temperature grain oriented electrical steel, the mechanism of the production of crisp edge was proposed in this paper. The edge quality of the grain oriented electrical steel has been improved by optimizing the slab load mode and edge heating mode,which was helpful to increase the non-trimming cold rolled rate as well as the finished product rate and reduce the production costs. |

| Keywords: | grain oriented electrical steel crisp edge non-trimming rolling edge defects |
