Abstract

Abstract

In this paper the solid solution behavior of the inhibitor under various holding time in 0.001 1 % La oriented silicon steel during reheating had been investigated by using OM, LM, methods of electrolytic extraction and mass spectrometer. The results showed that grain size of the test steel increased significantly with the holding time prolonging when the rare earth oriented silicon steel was heated to 1 250 ℃ and held for 10, 20 min and 30 min respectively, and the growth trend slowed down after holding time more than 20 minutes. As inhibitor elements, Mn, Cu and Al were all dissolving back, and holding time greatly influenced dissolution of Mn and Cu. The solid solubility of Mn and Cu increased from 69.8% and 43.7% to 84.2% and 85.2% respectively. Furthermore, with the prolongation of holding time, the insoluble small size inhibitors gradually decreased or even disappeared, and those larger ones gradually changed into small size insoluble substances and gradually dissolved into matrix in RE oriented silicon steel. The quantity decreased and the type of insoluble matter changed from complex to single gradually.
