Self-heating smelting furnace

Abstract

The invention discloses a self-heating smelting furnace, which comprises a furnace body, a furnace cover and a dentiform water jacket. The furnace body comprises a furnace shell and refractory brick layers arranged in the furnace shell; the furnace cover is used for sealing an opening at the top end of the furnace body; the dentiform water jacket is arranged in the furnace body and comprises a jacket body and a cooling medium channel; the cooling medium channel is formed in the jacket body and is provided with a cooling medium inlet for supplying cooling media and a cooling medium outlet for discharging the cooling media; and the surface of the inner side of the jacket body is a dentiform surface. According to the self-heating smelting furnace, the surface of the inner side of the dentiform water jacket is the dentiform surface, so refractory bricks of the smelting furnace can be matched in a groove so as to improve the combination performance of the dentiform water jacket and the refractory bricks and reduce gaps between the dentiform water jacket and the refractory bricks; and in addition, due to large contact area and good contact uniformity, the self-heating smelting furnace has excellent cooling effect.

Description

technical field [0001] The invention relates to a self-heating smelting furnace, in particular to a self-heating smelting furnace with a toothed water jacket. Background technique [0002] In the field of pyrometallurgy, in order to cool the smelting furnace, a cooling copper pipe or a cooling water jacket is usually provided in the furnace body. The contact surface between the cooling copper pipe and the refractory brick is small, and the cooling effect is poor. Traditional water jackets are usually flat, that is, the inner and outer surfaces of the water jacket are flat. When the water jacket is installed in the furnace body, there are gaps between the inner surface of the water jacket and the refractory bricks, the bonding performance is poor, the contact area is small, and the contact uniformity is poor, thereby reducing the cooling effect, especially around the molten pool in the lower part of the melting furnace Furnace body, because the temperature is very high, so ...

AI Technical Summary

Problems solved by technology

When the water jacket is installed in the furnace body, there are gaps between the inner surface of the water jacket and the refractory bricks, the bonding performance is poor, the contact area is small, and the contact uniformity is poor, thereby reducing the cooling effect, especially around the molten pool in the lower part of the melting furnace Furnace body, because the temperature is very high, so it needs better cooling effect, the above traditional water jacket cannot meet the cooling requirements, thus reducing the life of refractory bricks and increasing maintenance costs

[0003] In addition, the outside of the product outlet and the slag outlet of the traditional smelting furnace are easily damaged due to repeated opening and closing, and the service life is short. During maintenance, the product outlet and the slag outlet need to be completely replaced, which is difficult to operate and caused by long maintenance time. Reduced work efficiency
