退火温度对35ZW300无取向电工钢组织和性能的影响

Effect of the Annealing Temperature on the Structure and Magnetic Properties of 35ZW300 Non-oriented Electrical Steel

以35ZW300无取向电工钢为研究对象,研究退火温度对一次冷轧法生产的w(Si)不超过3.50%的薄规格无取向电工钢晶粒大小、磁性能的影响。实验结果表明:在不同退火温度下,随着退火温度的升高,晶粒尺寸逐渐增大,铁损先降低后略有提高;退火温度为940℃时铁损最佳。

35ZW300 non-oriented electrical steel is taken as the research object,the effect of annealing temperature on the grain size and magnetic properties of the thin non-oriented electrical steel are studied which w（ silica） content is less than 3. 5%. The results show that： at different annealing temperature,the grain size gradually increases with the increase of annealing temperature,the iron loss decreases first and then increases slightly. When annealing temperature is 940 ℃,iron loss is the best.
