Cold rolling condition and magnetic induction in a thin-gauged 3 % Si-Fe strip

The effects of the cold rolling condition and surface segregation of sulfur on the magnetic induction of thin-gauged 3 % Si-iron alloy strips have bee n investigated. During final annealing, segregated sulfur was observed on t he strip surface only within the final annealing time range until 1.2 ks. B ecause texture development is controlled by surface segregation and grain-g rowth kinetics, a cold rolling condition less severe than a critical condit ion should be chosen so that {110}[001] Goss grains can survive up to 1.2 k s and grow to form a complete {110}[001] Goss texture. A magnetic induction higher than 1.90 T Was obtained when a final reduction ratio of 60 % was c hosen.
