Abstract
The utility model discloses a filter for full-mold casting. Round filtering holes are arranged on a filter body, and the hole size of each filtering hole ranges from 4mm to 5mm. Compared with the prior art, the filter for full-mold casting has the advantages that the filtering holes are improved to the round filtering holes, the area of the filtering holes is widened, impurities in molten iron are filtered effectively by the filter, blockage during pouring is further avoided, and the molten iron passing rate is further increased.
Description
Technical field
The utility model belongs to the cavityless casting field, and specifically, the utility model relates to a kind of cavityless casting filter.
Filter the device of impurity in the molten iron in the casting process.
Background technology
In the fusion process of cast casting, owing in the molten iron of melting a certain amount of slag being arranged, skim before the cast and the slag in the molten iron can't be removed fully totally, can produce Secondary Oxidizing Slag in the molten steel pouring course, in the full mold casting process, the foam gasification not exclusively also might cause producing black residue, if in the running gate system without filter, these residues will be poured in the full mold, and surface and the inner cinder hole that produces at foundry goods affect casting quality.
Present filter used in the foundry goods cavityless casting is the filter housings corollary apparatus, and the filter bores during design on the filter is square hole, and single sectional area is 3mm * 3mm=9mm
2, the whole filter molten iron sectional area of flowing through is 680 * 9mm
2=6120mm
2, with ingate sectional area (2000 mm
2) ratio be 3.06, theoretical size is enough, but since in the use procedure single square hole sectional area too small, easily cause filter to stop up, may cause at last foundry goods to fill type and scrap.
The utility model content
Technical problem to be solved in the utility model provides a kind of cavityless casting filter that can not occur stopping up.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cavityless casting filter, be provided with filter bores at the filter body, and filter bores is circular hole, the aperture of filter bores is 4 ~ 5mm.
The aperture of described filter bores is preferably 4mm.
Described filter bores is provided with multirow at described filter body, and the filter bores between adjacent two row is interlaced arrangement.
The material of described filter is mullite.
The utility model adopts technique scheme, compared with prior art, the filter bores of correcting one's mistakes on the filter disc is circular hole, the area of filter bores strengthens, make filter in the impurity that effectively filters out in the molten iron, also avoided the appearance of clogging in the casting process, and the molten iron percent of pass is improved also.
Description of drawings
Fig. 1 is the structural representation of filter of the present utility model;
Mark among the above-mentioned figure is: 1, filter body; 2, filter bores.
The specific embodiment
Be illustrated in figure 1 as a kind of cavityless casting filter of the present utility model, be provided with filter bores 2 at filter body 1, filter bores 2 is circular hole, and the diameter of filter bores 2 is 4 ~ 5mm.Compared with prior art, the filter opening 2 of correcting one's mistakes is circular hole, and the area of filter bores 2 strengthens, and makes filter in the impurity that effectively filters out in the molten iron, also avoided the appearance of clogging in the casting process, and the molten iron percent of pass is improved also.
The aperture of the filter bores 2 of this cavityless casting filter is preferably 4mm, and the sectional area of single filter bores 2 is 3.14 * 2
2Mm
2=12.56 mm
2, filter bores 2 is provided with 17 row altogether on filter body 1, and the filter bores 2 between adjacent two row is interlaced arrangement, totally 425 of filter bores 2, the whole filter molten iron sectional area of flowing through is 3.14 * 2
2* 425mm
2=5338 mm
2, with ingate sectional area (2000 mm
2) ratio be 2.669, reach used 2 ~ 3.5 times standard of producing.
This filter is placed in ingate and cross gate junction, and its material is mullite, and the filter refractoriness of this material can improve filling velocity effectively greater than 1600 ℃, has reduced the cinder hole that produces on the foundry goods, and the quality of foundry goods is significantly improved.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
