Abstract
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%.
