Abstract
The invention relates to pouring basins, in particular to a slag blocking pouring basin which is used for large castings and has the slag blocking function. The slag blocking pouring basin is characterized by comprising a pouring basin body, the appearance of the pouring basin body and a slag blocking core are integrated, the pouring basin body is internally provided with a slag blocking dam used for dividing the pouring basin body into a front area and a rear area, a connection opening is formed in the bottom of the slag blocking dam, and a straight pouring gate opening is formed in the bottom of the pouring basin body and located on the rear side of the slag blocking dam. The slag blocking pouring basin is unique in structure, and can enable slag to fully float upwards in the pouring basin, ensure pressure of molten iron to be uniform and stable in the straight pouring gate area, reduce the possibility for slag to enter the castings, overcome the defects of the castings, save cost, improve efficiency, and eliminate the possibility of floating of a slug.
Description
Technical field
The present invention relates to pouring basin, especially relate to a kind of skim gate basin that possesses slag stopping function for a kind of heavy castings.
Background technology
Slag inclusion refers to the non-metallic inclusion that foundry goods is inner or surface exists, and the existence of slag inclusion all can produce important impact for interior tissue, surface quality, the mechanical performance of foundry goods, is the one of the main reasons that causes foundry goods to be scrapped.According to the priority of formation time, slag inclusion is divided into slag inclusion and secondary slag inclusion.One time slag inclusion mainly results from metal smelt and processing procedure, comprises the slag that reacts generation between inner each element of molten metal, element and extraneous gas, furnace lining tympaning, rotten material.Secondary slag inclusion results from after molten metal enters running gate system, is mainly derived from the secondary oxidation of molten metal in cavity filling process.Pouring basin is the vitals that guiding molten iron enters running channel, in splendid attire molten iron, can play the effect of a slag inclusion of isolation.Large-sized iron casting adopts the common pouring basins of simple plain base more at present, a little less than this pouring basin slag stopping function, and molten iron stirring during cast, turbulent violent, bits can not fully float, thereby enter running channel and foundry goods, cause foundry goods slag inclusion.Or adopt fuse form in the middle of pouring basin, to form dam, though also there is certain slag stopping function, but increased complexity and the cost of operation, also often occur in practical application that baffle core floats in casting process, the phenomenon that slag stopping function lost efficacy, has increased the risk of quality.
Up to the present, also there is no a kind of device that overcomes above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, a kind of structure uniqueness is provided, can makes slag fully float in pouring basin, and in down gate region, guarantee molten iron pressure homogeneous, steady, reduce the possibility that bits enter foundry goods, reduce casting defect, cost-saving, raise the efficiency, eliminated a kind of skim gate basin of the possibility of fuse floating.
The present invention realizes in the following way:
A kind of skim gate basin, it is characterized in that: it comprises the pouring basin that pouring basin external form and baffle core are integrated, in pouring basin, be provided with a dam that is divided into former and later two regions, dam bottom is provided with a connector, and sprue channel open is located at the pouring basin bottom of dam rear side always;
The cross section of described connector is flat;
Each face of described pouring basin inner side leaves 10 ~ 50mm pattern draft, and pouring basin height is greater than 5 times of down gate diameters;
Described dam is at the middle part of pouring basin.
The present invention has following effect:
1) structure unique, can make slag abundant floating in pouring basin, and in down gate region, guarantee molten iron pressure homogeneous, steady: it comprises the pouring basin that pouring basin external form and baffle core are integrated device provided by the invention, in pouring basin, be provided with a dam that is divided into former and later two regions, dam bottom is provided with a connector, and sprue channel open is located at the pouring basin bottom of dam rear side always; This device utilizes law of connected vessels, a slag inclusion is intercepted, and in casting process, liquid level can be consistent to greatest extent in pouring basin, guarantees that down gate place molten iron pressure is steady, fills type steady, reduces the possibility that foundry goods produces dreg defect.
2) improved operating efficiency, reduced labour intensity, saved material consumption: the present invention has cancelled the operations such as making, maintenance, transhipment and assembling of pushing off the slag core core box and pushing off the slag core, has improved operating efficiency, reduce labour intensity, saved material consumption.
3) the present invention has cancelled baffle core, has eliminated possibility and consequent quality risk that baffle core core floatation defect occurs.
4) pouring basin provided by the invention can adopt simple and easy metal die to make, and expendable mo(u)ld forever uses, and efficiency is high, cost is low, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that Fig. 1 of the present invention is along the cutaway view of A-A.
The specific embodiment
A kind of skim gate basin, as illustrated in fig. 1 and 2: it comprises the pouring basin 4 that pouring basin external form and baffle core are integrated, in pouring basin 4, be provided with a dam 1 that is divided into former and later two regions, dam 1 bottom is provided with a connector 2, sprue channel open 3 is located at pouring basin 4 bottoms of dam 1 rear side always, one side is accepted the molten iron that casting ladle injects, and molten iron enters an other side by the flat connector 2 of bottom, and sprue mouth 3 is arranged on this side.Before cast, at sprue mouth, place the mouth of a river stifled, until molten iron level height, reach while being greater than 5 ~ 10 times of down gate diameters, extract the mouth of a river stifled, molten iron injects.
The cross section of described connector 2 is flat, in coremaking process, can, by flat core or the porcelain tube of burying forming in advance in apperance, after back-up sand, molding, can form this connector.
Each face of described pouring basin 4 inner sides leaves 10 ~ 50mm pattern draft, is convenient to molding, guarantees mold thickness and sand mold intensity simultaneously, and pouring basin 4 is highly greater than 5 times of down gate diameters.
Described dam 1 is at the middle part of pouring basin 4.
