Abstract
The invention relates to a filter device in the casting process of a casting, and particularly relates to a filter screen seat. The filter screen seat is characterized by comprising a ceramic seat, wherein the longitudinal cross section of the ceramic seat is in a trapezoidal shape, and a flow gate is matched with the bottom of the ceramic seat. The filter screen seat has the advantages of convenience in use and multiple types, an old sand mold structure in the past is replaced by a ceramic standard part, and a professional filter device is formed in a casting system, so as to achieve the purpose of filtering molten iron to obtain a high-quality casting.
Description
Technical field
The present invention relates to the filter of a kind of foundry goods in casting process, especially relate to a kind of filtration reticulum.
Background technology
A foundry goods in process of production most important ring is casting process, especially nodular iron casting, owing to oxidation reaction easily occurring in casting process, the inner dregs that form.Therefore the running gate system of foundry goods should play pushing off the slag effect.Traditional running gate system generally, only by extending cross gate length to reduce molten iron flow velocity, arranges the object that the methods such as dam, slag trap realize pushing off the slag in running gate system.But filter effect is not clearly.Also there were in recent years some producers to release foam ceramic filter, were positioned in the cross gate of sand mold running gate system, molten iron was played to certain filtration.But the method does not fundamentally solve the problem that oxidation reaction occurs again by the molten iron after screen pack, and form the problems such as molten iron pollution because impacting sand mold running channel, filter effect is far from reaching re-set target.
Also do not overcome at present the device of above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, provide a kind of easy to use, type is various, with ceramic standard components, substitute in the past old sand mould structure, in running gate system, form professional filter, reach and filter a kind of filtration reticulum that molten iron obtains the object of premium casting.
The present invention realizes in the following way:
A filtration reticulum, is characterized in that: it comprises that a longitudinal section is trapezoidal ceramics seat, and ceramics seat bottom is combined with ingate;
Described ceramics seat top is square, and described ingate is one;
Described ceramics seat top is rectangle, and described ingate is one;
Described ceramics seat top is rectangle, and described ingate is two.
The present invention has following effect:
1) structure is unique, easy to use: filtration reticulum provided by the invention, and it comprises that a longitudinal section is trapezoidal ceramics seat, ceramics seat bottom is combined with ingate; In Design of Runner System process, increase the positioner that filters reticulum, during moulding, directly filtering base is received on positioner, form ceramics seat.
2) type is various: filtration reticulum square filtering reticulum provided by the invention, and ceramics seat top is square, described ingate is one; Also can be rectangle, described ingate be one or two; The filtering base of above three kinds of forms is all ceramic material, has strict dimension precision requirement.In modeling process, by filtering reticulum according to the positioner of critique system, be embedded in running gate system in advance.During mould assembling, filtration reticulum is cleaned out, placed suitable screen pack, complete mould assembling.Can meet the requirement of different foundry goods to filter capacity size.
3) realize running gate system after screen pack without sand.In industry, for screen pack, do not form professional corollary apparatus, use extensively, do not make screen pack play due effect.This filtration reticulum can increase the actual usable floor area of screen pack effectively, and adds the bearing capacity of strong filter, thereby promotes filter effect.
4) the various ceramic filter reticulums that the present invention forms, can realize scale, mass and use.
Accompanying drawing explanation
Fig. 1 is that the present invention is applicable to the front structural representation of placing the product of a screen pack of an ingate;
Fig. 2 is that the present invention is applicable to the front structural representation of placing the product of two screen packs of an ingate.
The specific embodiment
A filtration reticulum, is characterized in that: it comprises that a longitudinal section is trapezoidal ceramics seat 1, and ceramics seat 1 bottom is combined with ingate 2;
Described ceramics seat 1 top is square, and described ingate 2 is one;
Described ceramics seat 1 top is rectangle, and described ingate 2 is one;
Described ceramics seat 1 top is rectangle, and described ingate 2 is two.
Wherein the filtration reticulum shown in Fig. 1 is applicable to the front product of placing a screen pack of an ingate.Be generally used for poured weights little, the product that filter area is little, casting weight≤3T.
Filtration reticulum shown in Fig. 2 is applicable to the front product of placing two screen packs of an ingate.This filtration reticulum is large for poured weights, the product that filter area is large, casting weight >=8T.
