Abstract

Abstract

Trilaminar composite of Fe-6.5%Si alloy with 1.2 mm thickness and produced by coated casting combined with thermomechanical process had been rolled in temperature of 450～650℃. Microstructure of the composite plate after warm rolling had been observed, in the same time, its iron loss had been tested. And then, the composite plate had been carried out on diffusion annealing process where it was reheated up to 1150℃ and hold for 30 min. Iron loss of the composite after diffusion annealing had been investigated. Results showed that the 6.5% high silicon electrical steel cladding plate could be rolled down to 0.37 mm by warm rolling deformation when it was heated at 450～650℃. Warm rolling process has a great influence on the iron loss of the composite plate, and the influence is more obvious in strong magnetic field environment. Diffusion annealing process of 1150℃ for 30 min can significantly reduce iron loss of the warm rolled composite plate, and the maximum reduction is 98.9%. This research is helpful to improve the magnetic properties of three-layer 6.5% high silicon electrical steel composite plates.
