摘要

为探究铬、锰元素及退火温度对高强无取向硅钢性能的影响规律,借助OM、SEM、EBSD与万能拉伸试验机等分析不同制造工艺下3组不同含量铬、锰元素的无取向硅钢热轧、常化及退火处理后组织与性能。结果表明,试验钢热轧后组织不均匀,心部为沿轧向分布纤维状组织,边部为少量再结晶晶粒,常化处理能显著改善热轧板组织均匀性,消除热轧板中心部位的纤维状组织。经冷轧及退火后得到多边形铁素体晶粒,其中960 ℃退火,晶粒尺寸偏大,有利织构{100}组分体积分数减少,不利织构{111}组分体积分数增加,成分为0.2Mn-1Cr的1号试验钢960 ℃退火后铁损最大,磁感强度偏小;成分为0.5Mn-1Cr的2号试验钢930 ℃退火后,磁性能与强度等综合性能最佳,工频铁损P1.5/50为2.41 W/kg,高频铁损P1.0/400为17.36 W/kg,磁感应强度B5 000为1.638 T,抗拉强度为685 MPa。

Abstract

In order to study the effect of Cr,Mn and annealing temperature on the properties of high-strength non-oriented silicon steel,the microstructure and properties of three groups of non-oriented silicon steel with different Cr,Mn content under different manufacturing processes were analyzed by means of OM,SEM,EBSD and universal tensile tester. The results show that the structure of experimental steel is not uniform after hot rolling,and the core is distributed in fibrous structure along the rolling direction,and there are a small amount of receystallization grains at the edge. Normalized treatment can significantly improve the structure uniformity of hot rolled plate,promote recrystallization and eliminate the fibrous structure at the center of hot rolled plate. Polygonal Ferrite grains were obtained by cold rolling and annealing at 930 and 960 ℃. The grain size of the three groups of experimental steel annealed at 960 ℃ was larger,but the favorable {100} texture volume percent decreased and the unfavorable {111} texture volume percent increased. The steel with composition of 0.2Mn-1Cr and annealing at 960℃ has the largest iron loss and less magnetic inductance. After annealing at 930 ℃,the magnetic properties and strength of the steel of 0.5Mn-1Cr are the best:P1.5/50 is 2.41 W/kg,P1.0/ 400 is 17.36 W/kg,B5 000is 1.638 T,tensile strength is 685 MPa.
