摘要
本工作对耐热型取向硅钢薄板进行了分析,研究了退火温度对其涂层的影响,探索了复杂工况条件、拉应力及压应力对薄板磁性能的影响规律。结果表明:选取的耐热型取向硅钢薄板涂层附着性为C级和D级,涂层包含绝缘涂层和硅酸镁底层,刻痕区硅酸镁底层被严重破坏。退火对耐热型取向硅钢涂层表面绝缘电阻无明显影响,但影响涂层的附着性,耐热型取向硅钢带材表面的绝缘涂层不具备耐热性。过励磁与直流偏磁工况比谐波工况对带材损耗、噪声、磁致伸缩的影响更为明显。压应力对耐热型取向硅钢磁性能、噪声均产生不利的影响,而拉应力在一定范围内对损耗具有降低作用,同时不影响噪声。
In this work,heatproof grain-oriented silicon steel sheet were analyzed,the effect of annealing temperature on coating characteristics was studied,and the effects of complex working conditions and tensile stress and compressive stress on the magnetic properties of the sheet were explored.The results show that the coating adhesion of heatproof grain-oriented silicon steel sheet was grade C and grade D.The coating consists of insulating coating and magnesium silicate,and magnesium silicate layer in the scoring area is seriously damaged.Annealing has no obvious effect on the surface insulation resistance of heatproof grain-oriented silicon steel coating,but affects the adhesion of the coating.The insulation coating on the surface of heat-resistant oriented silicon steel strip don’t have heat resistance.Over excitation and DC bias have more obvious effects on loss,noise and magnetostriction than harmonic.Pressure stress has an adverse effect on magnetic properties and noise of heatproof grain-oriented silicon steel,while within limits tensile stress can reduce the loss and without affecting noise.
