The method of CSP process production high-magnetic induction, low-iron loss non-oriented electrical steel

The invention discloses a kind of methods of CSP process production high-magnetic induction, low-iron loss non-oriented electrical steel, are related to the production method of non-oriented electrical steel.The present invention is the following steps are included: step A: smelting；Step B: continuous casting；Step C: heating；Step D: hot continuous rolling；Step E: pickling；Step F: once cold rolling；Step G: annealing；Step H: secondary cold-rolling；Step I: recrystallization annealing.It is an object of the invention to overcome the existing CSP process production non-oriented electrical steel underproof deficiency of magnetic property due to cold rolling reduction ratio is excessive in the process, provide a kind of method of CSP process production high-magnetic induction, low-iron loss non-oriented electrical steel, so that the non-oriented electrical steel produced has the fine magnetic property of high-magnetic induction, low-iron loss under the premise of cold rolling total reduction is far longer than 85%.
