Why is China's transformer silicon steel sheet worse than Japan?
In silicon steel, China domestic still use 0.3MM ordinary steel, Japan has eliminated the use of this type of 0.23MM/0.27MM high magnetic induction of silicon steel has been the mainstream they now use the laser materials in China is 0.23 in the research phase of the trial did not have the ability to mass production. China's oriented silicon steel production line, Baosteel and Wuhan Iron and steel are imported from japan.
It should be said that they are the inventors of silicon steel.The production technology of silicon steel is completely Japan's own research and development, and improved for decades has not been short.
