METHOD OF REFRACTORY LINING OF CASTING LADLE FOR STEEL CONTINUOUS CASTING Russian patent published in 1997 - IPC

Abstract RU 2092278 C1

FIELD: metallurgy, in particular, steel continuous casting. SUBSTANCE: method includes successive laying of bricks of safety and working lining of walls and bottom of ladle body and gap with thickness of 0.008-0.12 of ladle bottom diameter between working linings of walls and bottom. Gap is filled with anhydrous mixture of the following composition, vol.%: magnesium sulfate 7-10; finely divided clay 8-10; the balance, magnesite powder. Then, ladle is heated up to 1200 C. At temperature up to 1000 C anhydrous mixture remains in yielding state and does not higher heat expansion of bricks. EFFECT: higher stability of refractory lining of ladles. 1 tbl
