简介 FIELD : metallurgy. SUBSTANCE : sheet after the surface exposure by laser or electronic beam has areas (X) of closing domains, formed to separate the magnetic domains in rolling direction, from one end to another through width of the steel sheet, ensuring meeting of the expression -(500t-80)×s+230≤w≤-(500t-80)×s+330, where t is sheet thickness (mm); w is minimum width of areas (X) (mcm), measured on face and rare surfaces of the steel sheet using the Bitter method; and s is average number of areas (X) in same crystalline grain. EFFECT : low hysteresis losses, and low coercitive force. 2 cl, 2 dwg, 3 tbl, 3 ex
