Description

Beam slag blocking pouring system

Technical Field

The utility model relates to the technical field of slag blocking pouring, in particular to a beam slag blocking pouring system.

Background

The parallel precision of the beam guide rail is the main precision of equipment operation, the parallel precision of the beam guide rail determines the combined operation precision of a machine tool, and meanwhile, whether the labor intensity of the assembly worker for scraping is reduced or not is determined, and the parallel precision cannot be processed in place at one time due to a plurality of reasons in the processing process of the beam guide rail, wherein the guide rail has impurities which tend to influence the performance of the guide rail.

In the prior art, the cross beam adopts a filter screen to stop slag, so that higher casting temperature is needed, because the temperature is low, the viscosity of molten iron is high, the fluidity is poor, the risks of cold insulation and insufficient casting are provided, and if the temperature is high, the risk of sand-bonding sintering is provided.

Therefore, how to provide a beam slag blocking pouring system, which can effectively avoid molten iron slag from entering a cavity, has become a technical problem to be solved by those skilled in the art.

Disclosure of Invention

The utility model aims to provide a beam slag blocking pouring system which can ensure purity of molten iron and prevent molten iron slag from entering a die cavity.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a beam slag blocking pouring system comprising: the sprue comprises a sprue and a runner communicated with the sprue, wherein the runner is provided with an upper runner, a middle runner and a bottom runner; molten iron slag floats on the upper runner and is placed in the empty space by a flashboard.

Wherein, the flashboard is refractory brick.

Specifically, the cross runner is communicated with an inner runner.

Compared with the prior art, the beam slag blocking pouring system has the following advantages:

in the beam slag blocking pouring system provided by the utility model, molten iron enters from the straight pouring gate and then enters into the transverse pouring gate, the transverse pouring gate is arranged into three layers, molten iron slag floats on the upper transverse pouring gate, the flashboard is used for placing a gap, so that the molten iron flows through the upper transverse pouring gate, most slag is blocked off by the flashboard, the molten iron passes through the middle transverse pouring gate after being baffled, slag blocking is performed again, and the impact force of the molten iron is buffered, so that the beam slag blocking pouring system provided by the utility model can improve the phenomenon of sand-sticking sintering of castings under the condition of low-temperature pouring, further can effectively reduce shrinkage, ensure the size and good appearance quality; in addition, the impact force of molten iron is effectively reduced, and molten iron splashing is avoided, so that primary inclusions and secondary oxide slag are reduced, and the internal quality and performance of castings are further ensured.
