Abstract:
     It is applied to various kinds of electrostatic induction equipments as well as large size electrical machinery, to save energy, raise electrical machinery efficiency and cause a decrease of the weight of electrical machinery. This kind of silicon steel sheet is obtd. by adding trace element As, Sb, Bi to Fe-Si-Al alloy so as to control deformation texture and recrystallization texture. In the alloy Si and Al is less than 4%. According to the trace element existing in steel, the quantity of trace element added to the alloy is controlled from 0.04%-0.1%.
