Tests on Fe -0.3% Si alloy have been performed on laboratory and industrial scale to define the process condition for high permeability semi-processed electrical steel production. Laboratory processing of the industrial hot band was performed taking into account different annealing temperatures and different cold rolling reductions. Microstructural analysis and texture measurement have been carried out on laboratory samples, and the process conditions to get high permeability materials have been defined. The process conditions have been applied on an industrial scale and a significant amount of semi-processed electrical steel has been produced. The industrial steel has been used for the construction of prototype single phase asynchronous motors.
