SOLUTION

Cold rolled silicon steel continuous decarburization annealing unit (CNGO)

Non-oriented silicon steel (CNGO) after cold rolling is surface degreased, and subjected to decarburization annealing and recrystallization annealing under a protective atmosphere to reduce the carbon content of the strip to a specified range, so that the grain grows and the magnetic level is improved., eliminate stress and apply insulation.
