Description
Technical field
The utility model relates to a kind of metallurgical industry and uses degasifying device, refers in particular to a kind of degasifying device of removing molten aluminium alloy hydrogen.
Background technology
Concerning the electrosmelting that present most of aluminium alloy smelting producer uses, composition of fumes mainly is a hydrogen.Because duraluminum has serious oxidation and air-breathing tendency, directly contacts with furnace gas or ambient atmosphere again in the fusion process, therefore; Improper slightly like control in the fusion process; Duraluminum forms ventilating microhole with regard to being easy to absorb gas, the duraluminum production practice prove that duraluminum is when melting and cast; Can absorb a large amount of hydrogen, then constantly separate out during cooling because of the decline of solubleness.Therefore aluminum alloy melt is in the refrigerative process of setting, and in a certain moment of hydrogen, the content of hydrogen has surpassed its solubleness and promptly separated out with the form of bubble.The bubble hydrogen that forms because of oversaturated hydrogen evolution; Have little time to float and discharge; Just in process of setting, form tiny, dispersive ventilating microhole, promptly usual our said pin hole, duraluminum is a hydrogen because of the air-breathing main gaseous constituent that forms ventilating microhole; And the no certain rules of its appearance can be followed, and whole or most foundry goods of a heat all have the pin hole phenomenon often; Material is no exception, and the duraluminum of various compositions all is easy to generate ventilating microhole, and modal is pin hole.How rounded, be non-uniformly distributed on the whole section of foundry goods, particularly at the thick and large section and the less position of speed of cooling of foundry goods.Pin hole mainly shows the influence of aluminium alloy capability foundry goods dense structure degree is reduced; Mechanical properties decrease; Pin hole be occur easily in the aluminum alloy casting and casting quality caused a kind of casting flaw of certain influence, and hydrogen is the major cause that causes pin hole.
In the aluminium alloy smelting Foundry Production, standing have online getter, is intended to improve the cleanliness factor of aluminium liquid at present; Reduce the generation of metallurgical imperfection; Getter commonly used at present adopts the rotor-type air-removal equipment usually, through the electric motor driving turning axle, drives the rotor and the impeller that link together with turning axle and in aluminium liquid, rotates stirring; Rare gas element is injected in the aluminium liquid through turning axle; And, take the hydrogen that is dissolved in the aluminium liquid out of aluminium liquid liquid level along with the rotation formation small bubbles of impeller are diffused in the aluminium liquid, reach the purpose of degasification.But rotor-type air-removal equipment complex structure, use and maintenance cost are too high, have increased the cost of product.
Therefore, how the influence of hydrogen is eliminated on efficient and cost-effective ground in fusion process, and the qualification rate that reduces the generation of ventilating microhole, the cleanliness factor that improves aluminium alloy solution and Al-alloy products becomes the problem that the scientific research personnel makes great efforts to solve in the industry.
