METHOD OF PRODUCING HOT-ROLLED ELECTRICAL-SHEET ANISOTROPIC STEEL Russian patent published in 1999 - IPC

Abstract RU 2125102 C1

FIELD: metallurgy, in particular, rolling; may be used in production of anisotropic electrical-sheet steel of medium alloying in coils. SUBSTANCE: method includes heating, hot rolling and cooling of strip prior to cooling in into coil. Strip in the mill line is cooled at rate of 0.8-1.5 C/s, and after rolling the cooling rate of strip is 56-69 C/s. EFFECT: reduced cooling rate down to 1 C/s to eliminate the necessity of heat treatment of ready rolling product.
