METHOD OF LIQUID METAL HEATING IN LADLE AND SHELL WIRE FOR ITS EMBODIMENT Russian patent published in 2002 - IPC

Abstract RU 2183221 C2

FIELD: metallurgy, particularly, ladle treatment of metallurgical melts; applicable in increase of temperature of cast iron and steel in intermediate ladle. SUBSTANCE: method includes introduction of shell wire to under level of liquid metal in ladle. Shell wire consists of metal shell and filler. Metal is heated in ladle due to exothermic reaction of burning of shell wire filler. Us is made of wire with filler in the form of alternating sections of exothermic mixture and sections of nonburning material of various length intended for interruption of process of exothermic mixture burning. Exothermic mixture is used in the form of iron oxides and one or several metals whose affinity for oxygen is higher than that of iron for oxygen. EFFECT: higher efficiency of heat process, removed limit for rapid heating of metal in ladle and provided control for process of chemical heating of metal in ladle. 4 cl, 3 tbl
