METHOD OF PRODUCTION OF ISOTROPIC ELECTRICAL-SHEET STEEL Russian patent published in 2003 - IPC

Abstract RU 2215796 C1

FIELD: ferrous metallurgy; production of isotropic electrical-sheet steel for magnetic circuit of electrical machines. SUBSTANCE: proposed method includes selection of temperature of normalizing taking into account content of silicon and phosphorus in steel. Temperature is found from the following equation: tnor = 950-45[Si,%]+100[P,%]±10°C at content of silicon of 1.6-2.69% and phosphorus of 0.05-0.15%. EFFECT: improved magnetic properties of isotropic steel. 1tbl, 1 ex
