Nonferrous metal liquid nine-column uniform purifying device

Abstract

The invention discloses a nonferrous metal liquid nine-column uniform purifying device, and relates to the technical field of metallurgy. The device comprises a degassing rake and degassing rods, one end of the degassing rake is fixedly provided with a plurality of degassing rods, the other end of the degassing rake is connected with inert gas, the degassing rake is connected with the degassing rods, and the degassing rods are uniformly distributed on the degassing rake. The nonferrous metal liquid nine-column uniform purifying device has the advantages of simple structure, reasonable design, uniform and thorough degassing, small artificial factor influences, degassing time saving, and improvement of the production efficiency and the production quality.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a nine-column uniform purification device for non-ferrous metal liquid. Background technique [0002] At present, in the smelting process of non-ferrous metals (taking the smelting process of aluminum or aluminum alloy products as an example), the process is roughly like this: first smelt and melt the raw materials, then alloy them, and finally purify them. Purification or refining is to use Some measures reduce the undesired gas or solid substances in the aluminum melt to the allowable range to ensure that the performance of the material meets the standards or some special requirements. The main impurities in the aluminum melt are hydrogen and aluminum oxide , so in a certain sense, the purification treatment of aluminum melt is mainly to reduce hydrogen and aluminum oxide to the required level or lower, while the traditional degassing device is a mobile degassing device, fir...

[0002] At present, in the smelting process of non-ferrous metals (taking the smelting process of aluminum or aluminum alloy products as an example), the process is roughly like this: first smelt and melt the raw materials, then alloy them, and finally purify them. Purification or refining is to use Some measures reduce the undesired gas or solid substances in the aluminum melt to the allowable range to ensure that the performance of the material meets the standards or some special requirements. The main impurities in the aluminum melt are hydrogen and aluminum oxide , so in a certain sense, the purification treatment of aluminum melt is mainly to reduce hydrogen and aluminum oxide to the required level or lower, while the traditional degassing device is a mobile degassing device, first put the degassing rake into the aluminum Then artificially move the degassing rake to remove as much and uniform hydrogen in the aluminum liquid as possible. This kind of degassing effect is greatly affected by human factors, and the degassing is uneven and incomplete. Based on this, a design is made. A nine-column uniform purification device for non-ferrous metal liquid is still necessary
