The invention discloses a method for promoting growth of GOSS textures of
silicon steel strips by using
pulse current. The method comprises the following steps of: conveying the
silicon steel strips at the speed of 2 to 10 meters per minute under the drive of a conveying device; and guiding the
pulse current of a
pulse power supply to a moving
silicon steel strip electrifying zone through a pair of
electric contact devices, and performing electric stimulation treatment on the silicon steel strip electrifying zone in
air atmosphere to promote the generation of a large amount of GOSS textures in the primary re-
crystallization process, wherein the silicon steel strips are in a high magnetic induction cold-rolled state, the thickness of the silicon steel strips is 0.1 to 0.5
millimeter, the width of the silicon steel strips is 10 to 150 millimeters and the silicon content of the silicon steel strips is 0.5 to 6.5 percent. Compared with the traditional
thermal treatment furnace annealing treatment process, the method has the advantages of low
energy consumption, high production efficiency and low production cost, and the GOSS textures in the primary re-
crystallization process have manycomponents. By
electron back-scattered
diffraction (EBSD) detection, the GOSS texture content of the silicon steel strips treated by adopting electric stimulation of the
pulse current reaches 15 to 25 percent.
