　　硅鋼是電力變壓器和電子變壓器用量最多、使用歷史最久的鐵芯材料。硅鋼的技術性能比較穩定，環境適應性能強，受溫度、機械應力的變化以及沖擊等的影響小，飽和磁通密度高，損耗小。變壓器常用的硅鋼有取向冷軋硅鋼和無取向冷軋硅鋼。
Silicon steel dosage of power transformer and electronic transformer is the most core material, use the oldest. Silicon steel technical performance is stable, environmental adaptation performance is strong, affected by the change of temperature, mechanical stress and impact is small, the influence of high saturation magnetic flux density, low loss. Transformer commonly used silicon steel with and without orientation orientation cold-rolled silicon steel cold-rolled silicon steel.
　　它們大多用于工頻變壓器中。近十多年中，開發了多種特殊硅鋼和薄帶硅鋼，已被用于中高頻變壓器中。硅鋼的用途和性能由于受到近年來快速發展的鐵基非晶合金和納米晶合金的挑戰，又興起了新的研究開發高潮，在技術性能、生產工藝技術上都有新的發展和進步。另外，硅鋼材料適合規模化生產，這也是能夠被廣泛大量使用的重要因素。

They are mostly used in power frequency transformer. For nearly 10 years, has developed a variety of special and thin silicon steel, silicon steel has been used in high frequency transformer in. The purpose and performance of silicon steel, due to the rapid development in recent years, iron base amorphous alloy and the challenge of nanocrystalline alloy, and the rise of a new research and development, on the technical performance, production technology has the new development and progress. In addition, the silicon steel material is suitable for mass production, it is also can widely use a lot of important factor.
　　1、鐵損低，這是硅鋼片質量的最重要指標。各國都根據鐵損值劃分牌號，鐵損愈低，牌號愈高。
1, low iron loss, this is the most important indicator of the quality of silicon steel sheet. All countries according to the division iron loss value brands, lower iron loss, the higher the brand.
　　2、較強磁場下磁感應強度高，這使電機和變壓器的鐵芯體積與重量減小，節約硅鋼片、銅線和絕緣材料等。
2, strong magnetic field of magnetic induction intensity is high, this makes the motor and transformer core size and weight is reduced, saving the silicon steel sheet, copper wire and insulation material.
　　3、表面光滑、平整和厚度均勻，可以提高鐵芯的填充系數。
3, the surface is smooth, smooth and uniform thickness, can improve the filling coefficient of iron core.
　　4、沖片性好，對制造微型、小型電動機更為重要。
4, stampings, used in fabrication of micro and small motors are more important.
　　5、表面絕緣膜的附著性和焊接性良好，能防蝕和改善沖片性。
5, surface insulation film adhesion and good weldability, corrosion and improve plate.
