Water jacket

Abstract

The invention discloses a water jacket which comprises a jacket body and a cooling medium channel, wherein the cooling medium channel is arranged in the jacket body and is provided with a cooling medium inlet used for supplying cooling media and a cooling medium outlet for discharging the cooling media, and the interior surface of the jacket body is a serrated surface. In the invention, the water jacket is provided with the serrated surface at the inner side of the jacket body (the surface facing the inner side of a smelting furnace when the water jacket is installed in the smelting furnace), i.e. bulges and recesses are arranged on the interior surface of the jacket body, therefore, firebricks in the smelting furnace can be matched in the recesses, thereby improving the binding ability of the water jacket and the firebricks, reducing gaps between the water jacket and the firebricks and achieving large contact area, good contact uniformity and favorable cooling effect.

Description

technical field [0001] The invention relates to a water jacket, in particular to a water jacket for a smelting furnace. 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 it needs better cooling effect, the abo...

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
