FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy and can be used to melt a metal-containing mixture. Smelting vessel comprises a refractory lined hearth and devices for draining molten slag and draining the molten metal, wherein the upper part of the hearth is in contact with the molten slag in the slag zone of the vessel, and the lower part of the hearth is in contact with the molten metal in the metal zone of the vessel, and a refractory lining cooler above the hearth, which is located completely around the top of the hearth. Cooler of the refractory lining of the upper part of the hearth is made in the form of heat pipes arranged in the refractory lining in the form of radially spaced rings.

EFFECT: invention allows to significantly reduce the wear of the hearth lining due to the use of a wide range of refractory materials and to obtain operational benefits due to a wider selection of materials.
