Integral type water cooling bottom part ring of combination holder of closed submerged arc furnace and process for producing same

Abstract

The invention provides an integral type water cooling bottom part ring of a combination holder of a closed submerged arc furnace and a process for producing the same. The bottom part ring consists of an inner side stainless steel ring-shaped plate (1), a water cooling protection sleeve insulated plate ring plate (2), a semi-circular ring body (3), a contact element protection support ring plate (4) and a clapboard (6), wherein the inner side stainless steel ring-shaped plate(1) is in welding connection with the stainless steel ring plate (2) and the contact element protection support ring plate (4); and the circular ring body (3) is in welding connection with the ring plate (2) and the contact element protection support ring plate (4) so as to form the integral type water cooling bottom part ring. The bottom part ring has the advantages of solving the problems of water leakage due to frequent poking and frequent shut-down of a furnace for exchange, meeting the operating requirements in the production of the combination holder of the closed calcium carbide furnace, effectively improving the quality of an electrode pole, greatly improving the use effect of the holder, fully meeting the requirements on protection and guide of an electrode pole electric conduction device, and avoiding water leakage phenomenon occurring while in use, along with better economical efficiency; moreover, the bottom part ring also has the advantages of greatly prolonging the service life and greatly lowering the frequency of the shut-down of the furnace due to the fault of the bottom part ring.

Description

technical field [0001] The invention relates to the technical field of smelting equipment, in particular to an integrated water-cooled bottom ring of a closed submerged arc furnace combination holder and a manufacturing process. Background technique [0002] At present, the bottom ring of the closed submerged arc furnace combined holder commonly used at home and abroad is made of T2 copper material divided into multiple pieces for casting or forging. This kind of bottom ring is formed by connecting multiple pieces during use. , it is very easy to deform and collapse, and it is very easy to cause fire and water leakage, which will cause the electrode cylinder to swell, and the electrode will not be pressed down, which will have a relatively large adverse effect on the operation control and furnace conditions of the submerged arc furnace. At the same time, due to the bottom The ring is made of T2 red copper material, so its manufacturing cost is relatively high, usually about ...

Problems solved by technology

[0002] At present, the bottom ring of the closed submerged arc furnace combined holder commonly used at home and abroad is made of T2 copper material divided into multiple pieces for casting or forging. This kind of bottom ring is formed by connecting multiple pieces during use. , it is very easy to deform and collapse, and it is very easy to cause fire and water leakage, which will cause the electrode cylinder to swell, and the electrode will not be pressed down, which will have a relatively large adverse effect on the operation control and furnace conditions of the submerged arc furnace. At the same time, due to the bottom The ring is made of T2 red copper material, so its manufacturing cost is relatively high, usually about 30,000 yuan per set, and it takes at least 20 hours to replace a set of bottom rings at the same time when the furnace is shut down. The structure of the inner material surface and the condition of the furnace will have a relatively large impact, which will have a relatively large negative impact on production costs, output and quality
