Description
Technical field
The present invention relates to a kind of die casting aluminium product a refining unit and technique thereof of watering.
Background technology
Cast aluminium alloy is little with its density, specific tenacity is high, plasticity good, electrical and thermal conductivity is good and the advantage such as easy processing, and is widely used in the every field such as aerospace, automobile, machinery and electronics.But cast aluminium alloy may cause foundry goods to produce a series of defect in fusion process, as pin hole, pore, slag inclusion etc.Therefore, how improving Melting Quality always is in the foundry goods actual production and needs the problem of thinking deeply.The inclusion of cast aluminium alloy in melting is mainly hydrogen and aluminium sesquioxide, if refinery practice is improper, continuity and the compactness of aluminium casting are damaged, and must reduce the performance of foundry goods.
The method of alloy refining is more, mainly is divided into absorption method and non-absorption method.Non-absorption comprises DC electrical method, pressure crystallization process and chemical combination degassing method etc., but these techniques rest on laboratory stage mostly, large-scale application, in actual production, certain distance is arranged still.Absorption method mainly comprises the working medium filtration method and the large class of method two of swimming, because the method for swimming is simple to operate and can not produce flux mixture, therefore the method for swimming be most widely used.
The method of swimming is when refined aluminum, passes into gas (Cl in aluminium liquid
2, N
2Or Ar), form bubble floating in aluminium liquid, in floating, the hydrogen in aluminium liquid diffuses in bubble, is dispersed into after bubble effusion liquid level airbornely simultaneously hydrogen to be taken out of, and reaches the purpose of dehydrogenation.Yet adopt Cl
2, though dehydrogenation has excellent effect, cause serious environmental pollution, rear employing N
2Or the non-active gas dehydrogenation such as Ar, need not exhaust-gas treatment facilities, become environment-friendly type technique.
Also have based on the floating Design Theory degasification of bubble bell jar in addition, use this bell jar can reduce the size of bubble, reduce the speed of bubble floating, extend floating interval of floating dock, simultaneously can avoid reacted impurity to carry out secondary pollution to aluminium liquid, bell jar adopts the high purity graphite manufacturing, can avoid again aluminium alloy to increase iron.
Britain FOSECO company also develops the rotor getter, is used for the aluminum alloy melt degasification.Its action principle is: rotor is broken up common rare gas element air pocket to become tiny bubble, and it is dispersed in molten metal, by reducing bubble diameter, bubble surface area is sharply increased, there is more inertia bubble surface to contact with impurity with the hydrogen in molten metal, thereby improve degassing efficiency.
Yet, the method of above-described refined aluminum all only is applied in the aluminium ingot calciner, water while being cast into the aluminium product when the aluminium liquid after refining being poured into mould, adopt artificial or mechanical means is poured aluminium liquid in holding furnace into, again via the holding furnace conveying aluminum liquid to mould, the aluminium liquid completed of refining can't contact with outside air or with the air in holding furnace with avoiding in the process that shifts like this, thereby cause the secondary suction hydroxide of refinery molten aluminium.
