By forging,primary normalizing and high temperature tempering,the reduction of area of a 45 steel magnetic yoke for electric machine was lower. Metallography observation indicates that slight banded structure exists in the steel magnetic yoke body.
某45钢电机磁轭锻造+一次正火+高温回火后断面收缩率偏低,金相观察发现在磁轭本体有轻微带状组织,返修件经二次正火+高温回火,消除了带状组织,断面收缩率达到了技术要求。
