METHOD OF PRODUCTION OF STRIPS FROM ELECTRICAL- SHEET GRAIN-ORIENTED STEEL

摘要

FIELD: monitoring and control of secondary re-crystallization in production of strips from electrical-sheet grain-oriented steel. SUBSTANCE: after annealing, blank obtained by continuous casting limited by number of emissions suitable for control of grain growth at cogging of approximately 70% is subjected to continuous nitriding for direct forming of nitrides suitable control of grain growth, thus making it possible to start secondary re-crystallization. EFFECT: increased productivity; low cost of process; possibility of performing monitoring and control of secondary re-crystallization. 9 cl, 10 tbl
