Problems solved by technology

However, the weight of this furnace cover is still very heavy, and because the temperature of the refractory bricks is very high, ash formation is equally serious, and ash formation is very troublesome to clean
In addition, due to the high temperature of refractory bricks, it is easy to age, which reduces the service life and needs to be replaced frequently, which increases the cost and maintenance work, reduces the efficiency, and cannot recover waste heat, wasting energy

Abstract

The invention relates to a metallurgical furnace, comprising a furnace body, and a furnace cover, wherein an opening is arranged at the top end of the furnace body, and the furnace cover is arranged at the top end of the furnace body to cover the top end opening of the furnace body and is provided with a cover body and a refractory layer. The cover body is respectively provided with a flue gas inlet, a flue gas outlet and a charging opening, wherein the cover body is composed of a membrane wall. The refractory layer is arranged on the inner wall of the cover body. According to the metallurgical furnace, the cover body of the furnace cover is composed of the membrane wall, so the weight of the furnace cover is light, the furnace cover can be fully cooled, the waste heat recovery efficiency is high, the dust accretion on the refractory layer in the cover body is reduced, the use life of the refractory layer is prolonged, and the maintenance is simple.

Description

technical field [0001] The present invention relates to a metallurgical furnace, and more particularly, the present invention relates to a metallurgical furnace with an improved mantle. Background technique [0002] Metallurgical furnaces are commonly used metallurgical industrial equipment, such as melting furnaces, flue gas furnaces, etc. The smelting furnace is widely used in the smelting of non-ferrous metals. During the smelting process, in order to effectively recover the waste heat of the smelting furnace, a waste heat boiler is usually installed above the smelting furnace. The waste heat boiler is connected to the smelting furnace through the The smelting furnace enters the waste heat boiler to recover the heat in the high-temperature flue gas through heat exchange. [0003] The hood body of the traditional metallurgical furnace is usually made of steel plates, such as welded with steel plates, with refractory materials inside, so the hood is very heavy. [0004] I...
