The effect of 0. 26% ~0. 95% Al content on structure

texture and magnetic performance of 0. 5 mm cold rolled sheet of 2. 2% Si non-oriented silicon steel has been studied by a 25 kg vacuum induction furnace smelting

and forging-rolling in laboratory. Results show that as 0. 26% ~0. 81% Al

with increasing Al content in steel the grain size of annealed finished sheet increases while iron loss of sheet decreases

and as Al content in steel is more than 0. 81 %

the grain size of sheet decreases while iron loss increases

but there is no obvious regular for the effect of Al content in steel on magnetic induction performance of silicon steel sheet. The suitable Al content in 2. 2% Si non-oriented silicon steel sheet is 0. 48% ~0. 81%.
