Abstract
The invention discloses a pouring channel structure for casting, which is capable of carrying out the last time processing of iron liquid before the iron liquid enters a casting mould, and guarantees the quality of the iron liquid before casting. The pouring channel structure comprises a first cross gate (1), a second cross gate (2), a filter (3) and alloys (4) for reacting with the iron liquid, wherein a plurality of alloys (4) are distributed on the bottom surface in the first cross gate (1); and the first cross gate (1), the filter (3) and the second cross gate (2) are successively connected from bottom to top so as to form a channel for flowing of the iron liquid from bottom to top, the iron liquid flows into the first cross gate (1) from an inlet of the first cross gate (1), and the iron liquid flows out from an outlet of the second cross gate (2).
Description
Technical field
The present invention relates to casting technology field, is specifically a kind of casting pouring gate structure.
Background technology
In castings production process, for checking on of the quality of iron liquid of casting own, it is the key of the foundry goods obtaining good quality, in prior art to the quality control of iron liquid mainly iron liquid processed before entering running channel, running channel is mainly considered for the control of iron liquid quality in pushing off the slag, in addition, the running channel stage just controls iron liquid quality without other measure.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of before iron liquid enters casting mold, can carry out the casting pouring gate structure of last process, thus before making to enter casting mold, the quality of iron liquid is guaranteed to iron liquid.
Technical scheme of the present invention is, the present invention casts with pouring gate structure, and it comprises the first cross gate, the second cross gate, filter, alloy for reacting with iron liquid, and the first cross gate inner bottom surface distributes some described alloys; First cross gate, filter, the second cross gate sequentially connect to form the passage flow through for iron liquid from bottom to top from bottom to top, and the entrance of the first cross gate is used for iron liquid and flows into, and the outlet of the second cross gate is used for iron liquid and flows out.
Operation principle of the present invention is, iron liquid flows into from the entrance of the first cross gate, and react with alloy contact, the second cross gate is flowed into again through filter, flowed out by the outlet of the second cross gate, thus achieving the last process to iron liquid before iron liquid enters casting mold by alloy and filter, the first cross gate, the second cross gate, filter also have unhurried current effect.
After adopting said structure, the present invention compared with prior art, has the following advantages: before iron liquid enters casting mold, can process for the last time iron liquid, thus before making to enter casting mold, the quality of iron liquid is guaranteed.
As improvement, filter is the filter plate being provided with some through holes, and like this, not only structure is simple, and is conducive to flowing molten iron large discharge and passes through.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
The present invention casts with pouring gate structure, it comprise the first cross gate 1, second cross gate 2, filter 3, for some described alloys 4 that alloy 4, first cross gate 1 inner bottom surface that reacts with iron liquid distributes; First cross gate 1, filter 3, second cross gate 2 sequentially connect to form the passage flow through for iron liquid from bottom to top from bottom to top, and the entrance of the first cross gate 1 is used for iron liquid and flows into, and the outlet of the second cross gate 2 is used for iron liquid and flows out.
Filter 3 is for being provided with the filter plate of some through holes.
In Fig. 1,2, the entrance of the first cross gate 1 is all connected in sprue 5, Fig. 2 the wall thickness eliminating the first cross gate 1, second cross gate 2.
Have employed four casting pouring gate structures of the present invention in Fig. 3, before entering the cross gate 6 that confluxes, last process is carried out to iron liquid, and enter casting mold by the ingate 7 of annular, by current process, effectively ensure that the quality of the foundry cast iron liquid of pressing outer shell ultra-large type nodular iron casting in 1,000,000 kilowatts of supercritical turbines, iron liquid is spheroidal graphite cast-iron; The alloy 4 adopted is to the alloy material that iron liquid processes in prior art.
