Abstract: | A production technology has been developed for high-silicon (~3% Si) isotropic electrical steel with superlow magnetic losses (P1.5/50 ≤ 2.70 W/kg for strip of rated thickness 0.50 mm). The influence of the temperature used in the normalizing annealing of vacuum-treated hot-rolled strip (<0.005% C) with complex alloying (>1% Al and >0.015% Sb) on the magnetic properties of the final isotropic electrical steel is investigated. Normalizing annealing increases the cubic orientation in the texture of the final steel, which lowers the magnetic losses. |
