Description
Technical field
The utility model relates to regenerated aluminum smelting equipment technical field, is specifically related to a kind of secondary aluminum closed non-pollution smelting device.
Background technology
Al and Alalloy density is little, specific tenacity is high, erosion resistance, oxidation-resistance, conduction and be hotly only second to silver and copper, and processibility is good, nontoxic, also have good low temperature reflecting properties, nonmagnetic, produce no spark, the multiple properties such as surface luster is attractive in appearance, energy surface daub on a wall.Be widely used in industry and the daily life fields such as building, transport, national defence, packaging.China is the production and consumption big country of aluminum products, but the bauxite resource of China is but very deficient, and current bauxite can exploit the time limit less than 30 years.Therefore, the market requirement constantly expanded and relative poor bauxite resource have become the bottleneck of China's Aluminum future development, and this contradiction facilitates developing rapidly of China Aluminum Recycling Industry.Adopting aluminium scrap production high-quality secondary aluminum, is the important step of China's aluminum i ndustry development.
Current China does not still form fairly perfect waste aluminum recovery system, and the recycling of aluminium scrap is comparatively original, and Comparison of Management is chaotic, and different quality, the phenomenon that dissimilar waste metal material mixes mutually are very general.And the secondary aluminum manufacturing enterprise of vast Sub-scale is without the melting of screening, what secondary aluminum composition was become very mixes, seriously polluted, greatly reduces the utility value of secondary aluminum; Also have and adopt manual sorting impurity, but can not well stop being mixed into of objectionable constituent iron, cause secondary aluminum iron-holder too high, secondary aluminum tensile strength and unit elongation is too low, poor fluidity, be difficult to the technical requirements reaching cast aluminium alloy.
Due to the source of aluminium scrap and composition very complicated, rational technology therefore must be adopted just to make it to obtain effective process.The quality of alloy product depends primarily on melting and casting link, and dehydrogenation, removal of impurities are the keys of founding operation.China in the past few decades between, in succession introduce the molten aluminium in-line purification technology that SNIF, MINT, ALPUR, RDU etc. are external advanced, also the independent development technology such as DDF, improve the refining level of China's molten aluminium to a certain extent.
But because the modern technique of introduction and the DDF technology of independent development require higher to pre-treatment, more weak to the adaptive faculty of aluminium scrap, and invest huge, complex process, cost are high, be difficult to adapt to the complicated reality in China's aluminium scrap regeneration industry aluminium source, cause most of aluminium scrap to regenerate enterprise still to adopt original smelting process, both easy contaminate environment, and waste aluminum recovery rate is low, secondary aluminum is second-rate, smelt the major cause of the higher present situation of energy consumption.
Traditional method mainly employing three step carries out melting to aluminium scrap, 1. slightly refines: utilize smelting furnace to carry out melting to the aluminium scrap containing various magazine, ingot casting after melting completes; 2. refining: say that the aluminium ingot after thick refining carries out melting again, add cleaner in fusion process, the impurity in removing aluminium, ingot casting; 3. process: the aluminium ingot after refining is carried out melting again, is processed into desired product as required; Traditional technology needs to utilize completely aluminium scrap through three steps, and due to through three fusion process, energy consumption is very large, and pollutant emission is many, impacts environment.
Along with country is to the attention of Nonrenewable resources recycle, the highly efficient regeneration of aluminium scrap utilizes the focus that will be research and invest.For this reason, the method developing the aluminium scrap highly efficient regeneration cast aluminium alloy that a kind of technique is simple, aluminium scrap strong adaptability, aluminium alloy quality are stablized, cost is low, aluminium recovery is high seems very meaningful, is also the key solving a prior art difficult problem.
