High magnetic induction and low iron loss cold rolled oriented silicon steel sheet is an urgent product in power industry. The higher the magnetism of the silicon steel sheet, the electrical appliances manufactured are: less power loss, small size, light weight, long service life, and less cooling oil for the manufactured transformer. In particular, it can solve the problem that large electrical appliances such as transformers larger than 360000 KVA use lower magnetism. Difficulties of oriented silicon steel sheet manufacturing and transportation cannot pass through railway tunnels and highway bridges.
