METHOD FOR PRODUCING ISOTROPIC ELECTRICAL STEEL Russian patent published in 2004 - IPC

Abstract RU 2230800 C2

FIELD: ferrous metallurgy, namely production of isotropic electrical steel used for making magnetic circuits of electric machines.

SUBSTANCE: method is realized due to calculation of optimal content of phosphorus at predetermined content of silicon in steel according to equation . Such equation may be used at change of silicon content in steel in range 1.5 - 3.2 mass % and phosphorus content in steel in range 0.03 - 0.10 mass %.

EFFECT: enhanced magnetic properties of isotropic steel.
