Conductive copper water jacket and casting process thereof

Abstract

The invention provides a conductive copper water jacket which is used on a metallurgical furnace or a high temperature furnace. The conductive copper water jacket comprises a copper base body, a cooling water channel, a water inlet pipe and a water outlet pipe, wherein the cooling water channel is arranged inside the copper base body; the water inlet pipe and the water outlet pipe are communicated with the cooling water channel; and the cooling water channel, the water inlet pipe, the water outlet pipe and the copper base body are of an integrated overall structure. The procedure of welding the water inlet pipe, the water outlet pipe, the cooling water channel and the copper base body is avoided; the problem of welding leakage is prevented; the cooling water channel is shaped at a time; the cooling water is directly contacted with the copper base body; the cooling effect is improved; the service life of the water jacket is prolonged; as the copper base body is doped with phosphorus, magnesium, arsenic and yttrium, the density of the copper base body is increased effectively, the copper crystallization is finned, and the electric conductivity and the heat-conducting property of the copper are increased.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and relates to a high-power cooling device, in particular to a conductive copper water jacket for metallurgical furnaces and high-temperature furnaces, and also to a casting process for the conductive copper water jacket. Background technique [0002] The conductive copper water jackets currently used in metallurgical submerged arc furnaces and high-temperature furnaces have built-in cooling water channels that are made by drilling holes in the copper substrate or casting built-in copper tubes. The disadvantages of the copper water jackets produced by these two processes are: : (1) The cooling water channel of the copper water jacket made by drilling is small, and the corners are all right-angled. arc, affecting conductivity and service life. (2) The water jacket with built-in steel pipe and copper pipe reduces the temperature of copper water during the pouring process, which leads to the fu...

Problems solved by technology

[0002] The conductive copper water jackets currently used in metallurgical submerged arc furnaces and high-temperature furnaces have built-in cooling water channels that are made by drilling holes in the copper substrate or casting built-in copper tubes. The disadvantages of the copper water jackets produced by these two processes are: : (1) The cooling water channel of the copper water jacket made by drilling is small, and the corners are all right-angled. Arcing, affecting conductivity and service life

(2) The water jacket with built-in steel pipe and copper pipe reduces the temperature of copper water during the pouring process, which leads to the fusion of the water jacket base and the steel pipe and copper pipe water channel, resulting in pores, sand holes, etc. It is also poor, it is prone to cracking and falling off during use, and the electrical and thermal conductivity is poor, and the service life is short
