METHOD FOR PRODUCTION OF ELECTRICAL ANISOTROPIC STEEL Russian patent published in 1994 - IPC

Abstract RU 2024622 C1

FIELD: metallurgy. SUBSTANCE: after oxidizing, the method involves taking a metal sample for determining nitrogen content then, after pouring out of metal and before blowing with argon, 0.3 kg/t of aluminium and titanium in the amount [Ti,%]=[N,%] is introduced on the ladle bottom. After blowing, a sample of metal is taken for analyzing the aluminium content and steel is alloyed with aluminium to a content of 0.015-0.030%. In the process of annealing the steel of terminal thickness to the temperatures of secondary recrystallization steel is saturated with nitrogen for forming the particles of inhibitor phase AlN. EFFECT: higher efficiency.
