Degrease the surface of the cold-rolled non-oriented silicon steel (CNGO), and perform decarburization annealing and recrystallization annealing in a protective atmosphere to reduce the carbon content of the strip to the specified range, so that the crystal grains will grow and the magnetic level will be improved , Relieve stress, and apply insulation layer.点击查看更多
The cold-rolled pickling and annealing process of stainless steel can be divided into intermediate annealing pickling and finished annealing pickling. The main purpose is to recrystallize the cold-rolled stainless steel after annealing to eliminate work hardening, so as to achieve the purpose of softening and improving mechanical properties. Pickling is used to eliminate impurities such as iron oxide scale produced in the annealing process and further improve the surface quality of the strip.点击查看更多
