Abstract
Procedeu de obtinere a benzilor electromagnetice din otel silicios, cu structura orientata si permeabilitate magnetica ridicata prin elaborarea unei sarje de otel cu un continut de maximum 0,7%C, 2,6....4,0% Si, 0,03....0,24¤ Mn, 0,01....0,09% S sausi Se, 0,015....0,4% Al, maximum 0,02% N maximum 0,5% Cu si maximum 0,035% B, turnare de lingouri, laminare la cald, laminare la rece, cu o reducere a grosimii de minimum 80% decarburarea otelului si recoacere a grosimii de minimum 80% decarburarea otelului si recoacerea finala, pentru formarea structurii orientate, protejînd suprafata benzilor înaintea recoacerii finale cu un grund pe baza de oxizi sau hidroxizi de magneziu, calciu, titan, mangan sau si compuside bor sau sulf caracterizat prinaceea ca în scopul îmbunatatirii proprietatilor electrotehnice ale benzilor, foloseste de preferinta un grund constituit din 100 parti MgO, 1....2 parti H3BO3, 1....5 parti (NH4)2SO4, precum si adaosuri de 10 parti TiO2 si 4 parti MnO2.
