METHOD FOR PRODUCTION OF TAPE FROM MAGNETIC STEEL AND SHEET Russian patent published in 1998 - IPC

FIELD: methods of production of tape from magnetic steel. SUBSTANCE: method involves production of tape from magnetic steel with oriented grains and thickness of less than 5 mm, containing more than 2 wt.-% of silicon, less than 0.1 wt.-% of carbon and elements-inhibitors of secondary recrystallization in corresponding amount, and iron, the balance; produced by continuous casting on cylinder or between two cylinders. Grains GOSS are produced in ingot mold as a result of contact of molten metal with cylinders having temperature of their surface below 400 C. Crystalline structure is formed containing grains with orientation {110} <001> in surface crust, i.e. on the surface of hardening zone by sharp cooling of steel at contact with cylinder or cylinders whose temperature of its (their) surfaces is below 400 C. EFFECT: higher efficiency. 14 cl, 3 dwg, 5 tbl
