METHOD OF MAKING ELECTRICAL SHEET STEEL WITH GRAIN ORIENTED IN PLANES (110)[001] WITH CONTINUOUS CASTING OF STRIP Russian patent published in 2006 - IPC C21D8/12

Abstract RU 2285058 C2

FIELD: production of strip and making electrical sheet steel with grain oriented in planes (110)[001].

SUBSTANCE: continuously cast thin strip is subjected to hot rolling and annealing for re-crystallization of structure. Parameters of technological process are so selected that strain/re-crystallization index (K*)^-1≥ is about 6500. This index is found from the following formula: (K*)^-1= (T_HBA)1n[ε^-0.15exp(7616T_HR)1n(t_c/t_f)], where T_HBA is strip annealing temperature, K; ε is intensity of strain at hot rolling; t_c is initial thickness of strip before hot rolling and t_f is final thickness of strip after hot rolling.

EFFECT: enhanced efficiency and reliability.
