Abstract (en)
[origin: EP0540405A1] Process for manufacturing a magnetic steel strip which has a thickness of less than 5 mm and contains, in composition by weight, more than 2 % of silicon, less than 0.1 % of carbon and elements which inhibit secondary recrystallisation in an appropriate quantity, the remainder being iron, obtained by direct casting on a cylinder or between two cylinders, which process is characterised in that a crystallisation structure is created, comprising {110} <001> oriented grains as a skin, that is to say at the surface of the quenching zone, due to the abrupt cooling of the steel in contact with the roll(s), the surface temperature of which is lower than 400 DEG C. <IMAGE>
