ABSTRACT:
The present invention concerns a process for the production of semiprocessed non oriented grain electrical steel. More precisely it provides a solution to the technical problem of obtaining non oriented grain sheet or strip characterized by high magnetic permeability and low magnetic losses. According to the invention, starting from a steel with a low S, N and C content, through appropriate selection of hot-rolling variables and high-temperature annealing prior to cold rolling, a big improvement is achieved in the magnetic characteristics of the product, thanks to a better compromise between grain size and crystal orientation.
