Iron Loss Measurement on 6.5wt%Si Composite Plate Prepared by Clad Casting and Conventional Rolling Processes

Abstract:

The 6.5wt%Si composite plate, which contains three layers and the middle one is about 10wt% ferrosilicon alloy, is fabricated by clad casting and conventional thermomechanical processes. Experimental results reveal that the high silicon composite plate could get lager plastic deformation on the traditional rolling mill. Microstructure of different stages such as hot rolling, warm rolling and heat treatment are observed by optical microscope. Defects appeared in core layer of 6.5wt% high silicon composite plate could be eliminated in the diffusion annealing process. The values of iron loss are investigated at different frequencies which thickness of these homogenous thin sheets are near 0.3-0.5mm. Measurement results of 6.5wt%Si alloy samples produced by chemical vapor deposition (CVD) and powder rolling processing (DPR), and 3wt%Si grain oriented steel are compared with samples prepared by laminar composite technique.
