WALL LINING FOR A METALLURGICAL FURNACE

摘要

The invention relates to metallurgy and can be used in other technical fields in which a reduction in the rate of erosion of a lining is required. A cooling element is disposed in a tuyere region inside a metallurgical furnace. This element is in contact with a lining which contains elements made from a thermally conductive material and is adjacent to the cooling element. The lining is comprised, across its entire width and height, of layers of materials with different thermal conductivities. The lining is in contact with the melt or with the gaseous atmosphere of the furnace. The thermally conductive material is an alloy of copper, nickel and iron. The alloy is selected such that the melting point thereof is not lower than the melting point of copper. The lining provides an increase in the working life of the refractory wall of a furnace in the melt bubbling regions and in the gaseous atmosphere of the furnace.
