Description
Technical field
The utility model relates to regenerated aluminum smelting equipment technical field, is specifically related to a kind of low-temperature energy-saving aluminium smelting apparatus.
Background technology
Al and Alalloy density is little, specific strength is high, corrosion resistance, non-oxidizability, conduction and be hotly only second to silver and copper, and processability is good, nontoxic, also have good low temperature reflecting properties, nonmagnetic, produce no spark, the multiple properties such as lustrous surface is attractive in appearance, energy top finishing.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 demand 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 aluminium, 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 aluminium manufacturing enterprise of vast Sub-scale is without the melting of screening, what secondary aluminium composition was become very mixes, seriously polluted, greatly reduces the value of secondary aluminium; Also have and adopt manual sorting impurity, but can not well stop being mixed into of harmful components iron, cause secondary aluminium iron-holder too high, secondary aluminium tensile strength and percentage elongation is too low, poor fluidity, be difficult to the technical requirement reaching Birmasil.
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 aluminum melt 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 aluminum melt to a certain extent.
But because the advanced technology of introduction and the DDF technology of independent development require higher to pre-treatment, more weak to the adaptive capacity 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 contaminated environment, and waste aluminum recovery rate is low, secondary aluminium is second-rate, smelt the main 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 melting 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 required product as required; Traditional handicraft 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 the attention that country recycles non-renewable resources, 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 Birmasil 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.
