The present disclosure relates to the technical field of iron and steel, in particular to an electrical steel with low iron loss and method for controlling tension thereof during decarburization annealing. A tension of each procedure of decarburization annealing of the electrical steel is controlled and adjusted respectively, and further combined with temperature of the decarburization annealing furnace, treatment time of the electrical steel in decarburization annealing furnace, and width and thickness of the electrical steel to prevent deflecting, cracking and narrowing of the electrical steel in the furnace and nodules on the bottom of roller. Compared with products of same brand, surface roughness and magnetic hysteresis loss of product are decreased by 10-20% and 10-15%.

The present disclosure relates to a technical field of iron and steel material, in particular to an oriented electrical steel with high magnetic induction and annealing method thereof. Impeccable secondary recrystallization and single Goss texture are formed by controlling the heating rate and the atmosphere of the annealing treatment, confirming beginning and ending temperature in accordance with different heating rate. The orientation density of the Goss texture is more than 145. The magnetic induction intensity Bis increased by 1-3% compared with products of same grade.
