以冷代热无取向电工钢应用中存在的问题

Problems in Replacement of Hot-rolled Electrical Steel with Cold-rolled

就国内电工钢以冷代热进展缓慢的原因进行了分析,主要是电机设计相关的技术数据没有进行更新,给中小电机设计制造带来困难。建议国家支持电器科学研究,修改相关技术手册,使电机设计满足使用冷轧电工钢的需要。

Reasons for slow progress in replacement of hot-rolled electrical steel with cold-rolled one in China are analyzed. The main reason should be that a tack of upgrading of related technical parameters for motor design presents difficulties for the design and manufacture of medium and small motors. It is suggested that the government support research work in electrical equipment and modify related technical manuals, to make motor design meeting the requirements of using cold-rolled electrical steel.
