ABSTRACT:
A molten silicon steel is continuously strip cast to a thickness approaching the aim final thickness of magnetic core laminations that are to be punched from the resulting steel strip. The strip is temper rolled and then annealed to produce stress relief and secondary grain growth. Recrystallization is avoided during cooling following strip casting and thereafter. The steel phase and predominant crystalline texture of the steel strip at its final thickness is the same as the steel phase and predominant crystalline texture that existed initially upon solidification from the molten state. The steel phase is body centered cubic. The crystalline texture is characterized by (100) planes of the unit cubes of the crystals lying in a plane of the strip parallel to the strip surface with random orientation of the (100) planes in that plane of the strip.
