软磁材料,又称工业纯铁,或称“阿姆可铁”,实际是一种含碳量极低的软钢,由炼钢平炉精炼而成。我国常用的牌号有DT1,DT2,DT3,DT4(表1)。软磁材料除了含有小的内应力外,同时具有低的矫顽力和高的磁导率,变形加工、切削性能好,是一种理想的导磁材料。在电力工业、电信工业、计算机技术中被广泛使用,其机械性能及磁性见表2。 1978年,我厂制造的“书报轮转印刷机” Soft magnetic material, also known as industrial pure iron, or “Amcroft”, is actually a kind of soft steel with extremely low carbon content, which is refined by a steelmaking hearth. Commonly used brands in our country have DT1, DT2, DT3, DT4 (Table 1). In addition to containing a small soft internal stress, but also has low coercivity and high permeability, deformation processing, cutting performance, is an ideal magnetic material. In the power industry, telecommunications industry, computer technology is widely used, its mechanical properties and magnetic table 2. In 1978, I plant manufacturing “Newspaper rotary printing press”
