Abstract
Manufacture method of oriented silicon steel having good magnetic performance is disclosed. The method comprises the following steps: 1) conventional smelting and casting into blank; 2) heating the blank and hot rolling into strip steel; 3) normalization process, i.e. two-stage normalization process including first heating to 1100-1200℃, then cooling to 900-1100℃ within 50-200s and rapidly cooling down in water of 10-100℃, during which, applying tension to the strip steel, and the stress applied to the strip steel is 1-200M/mm2 during the temperature range of 900℃-500℃; 4) cold rolling, i.e. one-step cold rolling or two-step cold rolling with intermediate annealing; 5) primary re-crystallization annealing, then applying final annealing comprising secondary re-crystallization annealing and purification annealing by coating annealing separant which mainly includes MgO. The invention optimizes the content and distribution of martensite in the steel plate after normalization by adjusting the stress applied to the steel plate while normalization transformation, so as to make the content of martensite in the range ensuring a better magnetic performance of the final products and optimize the magnetic performance of final products.
