Outline
In this paper, it is introduced the process of technical study on manufacturing paper-thin steel strip of grain oriented silicon steel with thickness of 0.08 mm for medium frequency equipment by taking the common grain oriented silicon steel (CGO) with thickness of 0.27 mm produced by our plant as raw material as well as studied the effects of heat treatment technology with different annealing temperatures and running speeds of unit (i.e. holding time) on magnetic property of grain oriented silicon steel. 900 ℃ × 10 m/min is determined to be the optimum heat treatment technology as well as the manufacturing process of paper-thin steel strip of grain oriented silicon steel with good medium and high frequency electromagnetic property that magnetic induction intensity B8 = 1.846 T, iron loss P1.5/400 = 11.15 W/kg and coercive force Hc = 53.57 A/m is obtained.
