Technical field
The utility model relates to a kind of filter, especially a kind of aluminum alloy smelting filter.
Background technology
In fusion process, there is the pollutant such as oxide inclusion and hydrogen in aluminium and alloy thereof, affects melt purity in melt, cause ingot casting to occur bubble, pore, the defect such as loose, directly has influence on outward appearance and the performance of aluminium product.Remove hydrogen and oxide inclusion in aluminium liquid, reduce impurity content, improve the purity of aluminum melt, the performance of improving aluminium alloy becomes most important.
In conventional cast technique, use foam ceramic filter can significantly improve the quality of mo(u)lded piece, the rate of reducing the number of rejects and seconds, and also extensive use in casting and rolling process.
The material of foamed ceramics mainly contains three kinds, carborundum, zirconia, aluminium oxide.
Foamed ceramics has good filtration to copper water, molten iron and aluminium liquid, utilizes unique 3-D solid structure, can stop, seizure, adsorption and oxidation be mingled with and other nonmetal inclusions.Axis body, cylinder body or complicated large part, accurate hardware are by foam ceramic filter, and product quality all can obtain highly stable, gratifying result.
In existing technology, publication No. is that the name of CN 101732907 A is called the innovation and creation of " foamed ceramics flat-panel filter ", it comprises foamed ceramics flat-panel, also comprise fixture, drainage trough, foamed ceramics flat-panel is embedded to fixture, the periphery of fixture is extended with drainage trough, and the open top area of drainage trough is greater than bottom area, is funnel-form; Further, fixture outline is corresponding with the outline of foamed ceramics flat-panel, and fixture inwall is provided with embedding groove, and foamed ceramics flat-panel edge is embedded in embedding groove.
Although these innovation and creation can be filtered, the effect of filtering is single, uses dumb, in use foamed ceramics easily damages, and use one deck foamed ceramics flat-panel to filter, filter effect is undesirable, and outward appearance and serviceability to product have a huge impact.
Utility model content
The utility model is for the deficiencies in the prior art, a kind of aluminum alloy smelting filter is provided, this filter can reduce hydrogen and the oxide inclusion in aluminum melt, thereby improve the performance of alloy product, and this filter apparatus configuration is simple, be convenient for changing foamed ceramics, by the combination of dark filtration and shallow filtration, filter effect is good.
In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is:
A kind of aluminum alloy smelting filter, comprises bracing or strutting arrangement and filter, and described filter is fixed by bracing or strutting arrangement; Described filter comprises shallow filter course and dark filter course, described shallow filter course and the dark filter course composition that superposes successively; Described bracing or strutting arrangement comprises the first bracing or strutting arrangement and the second bracing or strutting arrangement, and the top of the bottom of described the first bracing or strutting arrangement and the second bracing or strutting arrangement removably connects, and filter is arranged in the second bracing or strutting arrangement;
