Abstract

The utility model discloses a pouring gate structure for casting, which can perform the last time treatment on iron liquid to ensure the quality of the iron liquid before the iron liquid enters a cast mold. The pouring gate for casting comprises a first cross pouring gate (1), a second cross pouring gate (2), a filter (3), and a plurality of alloys (4) reacting with the iron liquid and being distributed on the inner bottom face of the first cross pouring gate (1); the first cross pouring gate (1), the filter (3) and the second cross pouring gate (2) are sequentially connected from bottom to top to form a channel for allowing the iron liquid to flow from bottom to top; and an inlet of the first cross pouring gate (1) is used for the iron liquid to flow in, and an outlet of the second cross pouring gate (2) is used for the iron liquid to flow out.

Description

Casting running channel structure

Technical field

The utility model relates to casting technology field, specifically is a kind of casting running channel structure.

Background technology

In the castings production process, for checking on of the quality of iron liquid of casting usefulness own, it is the key that obtains the foundry goods of good quality, quality control to iron liquid in the prior art mainly is that iron liquid was finished dealing with before entering running channel, running channel mainly is to consider aspect the pushing off the slag for the control of iron liquid quality, in addition, the running channel stage does not just have other measure and comes iron liquid quality is controlled.

The utility model content

The technical problems to be solved in the utility model is, provides a kind of before iron liquid enters casting mold, can be to the casting that iron liquid is handled for the last time running channel structure, enter that the quality of iron liquid is guaranteed before the casting mold thereby make.

The technical solution of the utility model is, the utility model casting running channel structure, and it comprises first cross gate, second cross gate, filter, be used for the alloy with the reaction of iron liquid, the some described alloys of distribution on the first cross gate inner bottom surface; First cross gate, filter, second cross gate connect to form the passage that flows through for iron liquid from bottom to top in regular turn from bottom to top, and the entrance of first cross gate is used for iron liquid and flows into, and the outlet of second cross gate is used for iron liquid and flows out.

The utility model operation principle is, iron liquid flows into from the entrance of first cross gate, and contact with alloy and to react, flow into second cross gate through filter again, outlet by second cross gate is flowed out, thereby realized that by alloy and filter to the last processing of iron liquid, first cross gate, second cross gate, filter also have the unhurried current effect before iron liquid enters casting mold.

After adopting said structure, the utility model compared with prior art has the following advantages: before iron liquid enters casting mold, can handle for the last time iron liquid, thereby the quality that enters the preceding iron liquid of casting mold is guaranteed.

As improvement, filter is the filtration flat board that is provided with some through holes, and is not only simple in structure like this, and is conducive to the big flow of flowing molten iron and passes through.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

The utility model casting running channel structure, it comprises first cross gate 1, second cross gate 2, filter 3, be used for the some described alloys 4 of distribution on alloy 4, the first cross gates 1 inner bottom surface with the reaction of iron liquid; First cross gate 1, filter 3, second cross gate 2 connect to form the passage that flows through for iron liquid from bottom to top in regular turn from bottom to top, and the entrance of first cross gate 1 is used for iron liquid and flows into, and the outlet of second cross gate 2 is used for iron liquid and flows out.

Filter 3 is for being provided with the filtration flat board of some through holes.

The entrance of first cross gate 1 has all connected sprue 5 among Fig. 1,2, has omitted the wall thickness of first cross gate 1, second cross gate 2 among Fig. 2.

Four the utility model casting running channel structures have been adopted among Fig. 3, before entering the cross gate 6 that confluxes, iron liquid has been carried out last processing, and enter casting mold by the ingate 7 of annular, by current processing, effectively guaranteed to press in 1,000,000 kilowatts of supercritical turbines the quality of the foundry cast iron liquid of outer shell ultra-large type nodular iron casting, iron liquid is spheroidal graphite cast-iron; The alloy material of alloy 4 in the prior art iron liquid being handled that adopts.

Claims

1. a casting running channel structure is characterized in that, it comprises first cross gate (1), second cross gate (2), filter (3), be used for the alloy (4) with the reaction of iron liquid, and some described alloys (4) distribute on first cross gate (1) inner bottom surface; First cross gate (1), filter (3), second cross gate (2) connect to form the passage that flows through for iron liquid from bottom to top in regular turn from bottom to top, the entrance of first cross gate (1) is used for iron liquid and flows into, and the outlet of second cross gate (2) is used for iron liquid and flows out.

2. casting according to claim 1 running channel structure is characterized in that, filter (3) is for being provided with the filtration flat board of some through holes.
