IRON-MELTING FURNACE WITH LIQUID BATH Russian patent published in 2012 - IPC C21B13/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to an iron-melting furnace with a liquid bath, which produces iron melt by melting of iron-containing stock, for instance, melting of hard recovered iron and scrap. The iron-melting furnace with the liquid bath is arranged to ensure loading of iron-containing stock together with carbonaceous material and sludge-containing material, introduction of oxygen-containing gas, melting of iron-containing stock with combustion heat developed when burning a carbonaceous material and/or carbon of iron melt with production of iron melt and melted sludge. The oven comprises an oven body and multiple outlet holes, which stretch through an oven body, are provided in positions that differ from each other along the body height. Outlet holes are arranged as capable of their serial use depending on the extent of lining wear for interrupted discharge of both iron melt and melted sludge, by switching one after another to the highest outlet hole and transition to the lower ones while maintaining the oven body in a direct position with the possibility of producing and saving the amount of the retained iron melt.

EFFECT: iron-melting oven with a liquid bath has considerable resistance of line while maintaining stable high efficiency.
