Abstract
Method for producing a magnetic steel strip having a thickness of less than 5 mm and containing, in composition by weight, more than 2% silicon, less than 0.1% carbon and a suitable amount of secondary recrystallization inhibiting elements, the balance being iron, obtained by a direct casting on one roll or between two rolls, characterized in that it comprises creating a crystallization structure comprising oriented grains {110} <001> in the skin, i.e. on the surface of a quench zone, by the sudden cooling of the steel in contact with the roll or rolls whose surface temperature is lower than 400.degree. C.
