METHOD FOR HIGH TEMPERATURE ANNEALING OF COILS OF ANISOTROPIC ELECTRICAL STEEL WITH THICKNESS (0,25- 0,5) MM Russian patent published in 2002 - IPC

Abstract RU 2190026 C2

FIELD: ferrous metallurgy, namely manufacture of anisotropic electrical steel by high temperature annealing of steel strips in hood furnaces. SUBSTANCE: method comprises steps of placing coils of electrical anysotropic steel by stack; placing heating hood; heating steel until temperature of annealing; soaking steel; turning off heating members; removing hood. Novelty is hood removal when temperature achieves (105-175)C in zone of furnace. EFFECT: enhanced quality of surface of electrical steel due to lowered number of fracture type flaws. 1 tbl, 1 ex
