Abstract

The invention discloses a vacuum refining degassing device for aluminum casting. The device is used for being installed on an exhaust port of aluminum casting equipment. The device comprises a combustion box and a purification box. The combustion box is provided with an air inlet pipe used for being communicated with the exhaust port of the aluminum casting equipment, and the air inlet pipe is communicated with the interior of the combustion box. The combustion box is also connected with an air guide pipe, and the other end of the air guide pipe is communicated with the purification box. In the fusion casting production process, substances which are not sufficiently combusted in fusion casting production are effectively combusted, meanwhile, dust and sand in smoke are atomized and prevented from being discharged, a filtering effect is achieved, the discharged smoke is minimized, and the maximum cleanliness is achieved.

Description

technical field [0001] The invention relates to the field of degassing devices, in particular to a vacuum refining degassing device for aluminum melting and casting. Background technique [0002] Aluminum melting and casting is a method in which materials are directly cast into products after being melted at high temperature. Generally, it is melted in an electric arc furnace, then poured into a high temperature resistant mold, and then cooled to crystallize, annealed or cut to make products. In the production, the melting atmosphere, melting temperature and cooling conditions are mainly controlled to ensure high production efficiency, meet the requirements of crystallization and form a network structure. However, in the process of cooling and crystallization, due to the inconsistent crystallization temperature, grain segregation occurs and concentrated cavities—shrinkage cavities are formed inside the product. [0003] Among them, aluminum melting and casting will produce...
