硅钢片是电感镇流器的基本构成材料，硅钢片的磁性能直接关系到电感镇流器的功耗、温升及寿命等项技术指标，合理地选择硅钢材料及其工作点和严格地检测其磁性能，无论对于产品的设计者还是制造者都是十分重要的。在国外大量采用、在我国即将得到推广的节能型电感镇流器，对硅钢片材料性能的测试提出更高的要求。
Silicon steel is the basic composition of the inductor ballast materials, silicon magnetic properties of the magnetic ballast directly related to the power consumption, temperature rise and life and other technical indicators, a reasonable choice of silicon steel materials and their work points and strict testing Its magnetic properties, both for product designers and manufacturers are very important. Extensive use of foreign countries in China to be promoted energy-saving inductive ballast, silicon steel sheet material properties of the test put forward higher requirements.
