METHOD AND APPARATUS FOR CONTINUOUS SMELTING OF METAL MELTING STOCK Russian patent published in 1994 - IPC

FIELD: metallurgy. SUBSTANCE: metal scrap and/or iron are loaded in a bath of an aggregate. Gas-type fuel and oxygen by radial sprays through side walls are fed into restoring tongue of flame over molten bath in the lower part of the aggregate. Oxidizer is fed over the fuel spray in quantities, that are necessary for full burning of the fuel. Then metal and slag through holes in a side wall are poured out into a ladle. Oxygen is fed into the restoring tongue of flame with oxidizer consumption factor of 0.8 - 0.9. Metal is poured out together with slag. During change of ladle after it is filled, the aggregate is inclined so, that the level of the molten bath is lower, than pouring out holes. Apparatus to realize the method has at least one burner, located on a wall of a transitional receiver coaxially with one of its canals. Pouring out canal of the transitional receiver is made in parallel to longitudinal axis of the body. An air lance is located over burners. The body is mounted on the transverse shaft and is capable to turn. EFFECT: method and apparatus are used for continuous smelting of metal melting stock. 5 cl, 1 dwg
