Fabrication of 6.5wt%Si Composite Plate by Coat Casting and Hot Deformation Processes

Article Preview

Abstract:

The high silicon electrical steel composite plate, which contains Q235 low carbon steel and 10%Si ferrosilicon alloy, is fabricated by coat casting and hot rolling. The bonding strength, microstructure and distribution of elements of the coating and core layers are analysed by the photographs of metallographic phase and EDS. Experimental results show that the high silicon composite plate could carry out lager plastic deformation by conventional hot mill after the 10%Si ferrosilicon alloy coated by Q235 low carbon steel in the vacuum induction furnace. The uniform distribution of elements could be achieved through the diffusion annealing process after the stage of hot rolling processing. This study provides a referable method to produce the 6.5wt% high silicon electrical steel plates.
