Method for manufacturing cooling element and cooling element

Abstract

The invention discloses a method for manufacturing a cooling element. A copper substrate is welded with a stainless steel shroud plate by an explosive welding method, so that the cleaning degree of the welding surface on a welding piece can be improved; and the heating time of the welding piece during welding is short, so that the degree of heated oxidation of the welding surface is reduced, and the reliability of welding is improved. The invention also provides the cooling element manufactured by the method. Due to the adoption of the explosive welding method, the degree of oxidation of the surface of the welding piece is reduced, and the generation of oxides on the copper substrate is avoided, so that the welding quality of the cooling element is improved, and the operating reliability of the cooling element is improved. In addition, the cooling element is welded with the stainless steel shroud plate and an overlaying layer, and the stainless steel shroud plate and the overlaying layer can prevent a metallurgical furnace from damaging the copper substrate directly, so that the damage resistance of the cooling element is improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a cooling element applied to metallurgical furnace equipment and a manufacturing method of the cooling element. Background technique [0002] The cooling element is a component used in the metallurgical furnace to cool the heat-resistant bricks in the metallurgical furnace. The cooling element includes a main body of the cooling element and a cooling water circulation pipeline opened on the main body of the cooling element for the circulation of cooling water. In the prior art, the cooling element is attached to the outside of the heat-resistant brick, and cooling water flows through the cooling water channel, and the cooling water achieves the purpose of cooling the heat-resistant brick through heat exchange. However, because the working environment in the metallurgical furnace is a high-temperature environment, and the slag corrodes the heat-resistant bricks, i...

AI Technical Summary

Problems solved by technology

The weldment is welded by the thermal welding method. Since the weldment maintains a high temperature state for a long time, it is easy to cause oxidation of the weldment, resulting in oxides on the surface of the weldment

After improving the structure of the cooling element, the surface of the cooling element has a corrosion-resistant surface, which solves the leakage problem of the cooling element. Copper sulfate is generated on the shell, and copper sulfate is easy to cause the welding parts to fall off, resulting in reduced working reliability of the cooling element
