Abstract
The utility model relates to a foamed ceramic slab filter. The foamed ceramic slab filter comprises a foamed ceramic slab and is characterized by the inclusion of a fixed device and a flow guide groove; the foamed ceramic slab is embedded in the fixed device, and the flow guide groove extends on the periphery of the fixed device and has an opening which is larger than the bottom in area and presents a funnel shape. During the processing of metal in molten state, the foamed ceramic slab filter filters inclusions in castings, reduces the gas in the castings, lowers turbulence degree in the process of filling molten metal flow, reduces surface defects of castings, remarkably reduces reject rates of castings, and ensures the filtering quality of the molten metal liquid. In addition, being integrated for the filtration according to the angle and the depth of the flow guide groove, the foamed ceramic slab filter has higher and steadier metal flow rate, and can not cause the blockage of the filter. The utility model facilitates the installation and the replacement of the foamed ceramic slab filter, thereby being in favor of popularization and operation in the industry.
Description
Technical field
The utility model relates to the filter under a kind of metal melting state, relates in particular to a kind of foamed ceramics flat-panel filter.
Background technology
The pore that produces in slag inclusion in the metal melting process and the casting cycle occupies larger specific gravity in casting defect.In Foundry Production, the casting wasted product rate that is caused by non-metallic inclusion is generally up to 50%～60% of waste product sum, adopts the filter filtering metal liquid then can positive significantly field solid-holding and the waste product brought into of impurity.Casting filter commonly used has: cloth shape well strainer, common porous ceramic filter.
But existing ceramic filter has often adopted the manufacturing process of one casting, and in other words pottery constitutes one fully with the miscellaneous part of filter basically, in case pottery then tends to discard whole ceramic filter because of filter life needs to eliminate.Simultaneously, present ceramic filter does not reach best filter effect to the not so well control of the flow of metal.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of foamed ceramics flat-panel filter is provided.
For realizing the purpose of this utility model foamed ceramics flat-panel filter, include foamed ceramics flat-panel, wherein: also include fixture, drainage trough, foamed ceramics flat-panel embeds fixture, the periphery of fixture is extended with drainage trough, drainage trough open top area is funnel-form greater than floor space.
Further, above-mentioned foamed ceramics flat-panel filter, wherein, described fixture outline is corresponding with the outline of foamed ceramics flat-panel, and the fixture inwall is provided with embedding groove, and the foamed ceramics flat-panel edge embeds in the embedding groove.
Further, above-mentioned foamed ceramics flat-panel filter, wherein, described fixture is provided with an active edges at least, when active edges is opened, fixture is " Qian " jaggy word shape.
Further, above-mentioned foamed ceramics flat-panel filter, wherein, the angle that described drainage trough and foamed ceramics flat-panel constitute is at 45～80 °.
Further, above-mentioned foamed ceramics flat-panel filter, wherein, described foamed ceramics flat-panel length is that described foamed ceramics flat-panel length is 200～260mm, wide 25～150mm, thick 10～30mm.
Further, above-mentioned foamed ceramics flat-panel filter, wherein, described foamed ceramics flat-panel length is 240mm, wide 100mm, thick 20mm.
Further, above-mentioned foamed ceramics flat-panel filter, wherein, the described degree of depth that is the funnel-form drainage trough is 300～500mm.
Again further, above-mentioned foamed ceramics flat-panel filter, wherein, the periphery and the drainage trough of described fixture are welded to connect.
Adopt technical solutions of the utility model, can in to the process of metal working of molten condition, filter the field trash in the foundry goods, reduce the gas in the foundry goods, turbulence level when the reduction metal liquid stream fills type, reduce the blemish in the foundry goods, reduce the percent defective of foundry goods significantly, guarantee the filter quality of molten metal bath.And according to the angle and the degree of depth combination of drainage trough, it is stable to have bigger metal flow rate and flow rate, can not cause the obstruction of filter.Moreover, adopting foamed ceramics flat-panel, it has very high chemical stability, is not subjected to the influence of molten metal Acidity of Aikalinity, does not change the chemical composition of molten metal.The more important thing is,, make things convenient for the installation and the replacement of foamed ceramics flat-panel by structure of the present utility model.This shows that the utility model is worth promoting in the art.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is that fixture was in conjunction with the schematic diagram of foamed ceramics flat-panel after active edges was opened;
Fig. 2 is after active edges is closed, and fixture is in conjunction with the schematic diagram of foamed ceramics flat-panel;
Fig. 3 is the foamed ceramics flat-panel filter organigram that adopts the monolithic foamed ceramics flat-panel;
Fig. 4 is the foamed ceramics flat-panel filter organigram that adopts two foamed ceramics flat-panels.
The implication of each Reference numeral is as follows among the figure:
1 foamed ceramics flat-panel, 2 fixtures
