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.

Hot And Cold Rolling

Crystallographic texture has an important effect on the magnetic quality of electrical steel: a specific texture parameter A is defined and used to estimate the magnetic quality of texture components. It is shown that obtaining the best possible texture in non oriented electrical steel can reduce the losses with 1,5 W/kg. Two production schemes for high silicon electrical steel are described: a conventional processing through hot and cold rolling with adequate temperatures and cooling rates and an immersion-diffusion process by hot dipping in a Si- and Al-rich bath followed by diffusion annealing. The texture evolution in these experimental materials is under study and first results are reported for conventional alloys (rolling procedure) and for immersion-diffusion alloys, which are annealed after dipping in order to obtain a controlled concentration gradient with high Si and/or Al at the surface or a homogeneous Si and/or Al-content over the thickness.
