鞍钢第二薄板厂自生产热轧电工硅钢片以来,对钢片的浪形缺陷一直没有进行过研究,以致长期未能按国家标准交货。用户反映:浪形过大的钢片经冲剪后扭曲严重,不仅降低迭装系数,增加磁化电流和铁芯损失,影响产品的使用寿命,而且使变压器和电机的制造工艺复杂化,严重地降低劳动生产率。特别是很难用来制造大功率的电气设备。
The second sheet mill in Anshan Iron and Steel since the production of hot-rolled electrical silicon steel sheets, the wave has been studied on the flaw defects, resulting in long-term failed to deliver according to national standards. The user reflects that the steel sheet with excessive waves is severely distorted after punching and shearing, which not only reduces the overlapping coefficient, increases the magnetizing current and core loss, affects the service life of the product, but also complicates the manufacturing process of the transformer and the motor. Reduce labor productivity. Especially difficult to manufacture high-power electrical equipment.
