Background

In the low-pressure casting production process of the aluminum alloy hub, the most common raw material is A356 aluminum alloy, and the A356 aluminum ingot is usually melted, stood, refined and transferred to a die casting machine for use. In the whole smelting process, the most critical process is refining, the quality of a hub product is directly related to the quality of the hub product or slag inclusion, air holes, cracks, shrinkage porosity and the like are brought about, the most common mode in the refining process is to add a slag removing agent into molten aluminum in a ladle, stir the mixture, blow in high-purity nitrogen by a rotor degassing machine, remove hydrogen and remove slag to achieve the refining effect, but the slag removing effect is poor due to the fact that particles in the slag removing agent are large, and the slag removing agent cannot fully react with aluminum slag. In addition to the above-mentioned method, there is another method that a slag removing agent is added into a graphite rotor of a rotor degassing machine, but this method has a disadvantage that the rotor is easily blocked by larger slag removing agent particles, and after the blockage, the rotor is difficult to clean, which directly results in the rotor being scrapped.

Because of the influence of large particles, source problems or damp coagulation into particles of the slag remover, and the like, almost all hub enterprises separate the processes of blowing high-purity nitrogen and adding the slag remover, and therefore, the slag remover is very necessary to be crushed.

In the technical scheme, the blades are blade-shaped, and the number of the blades is 2 or more.

In the above technical solution, the conveying pipe includes a downward inclined section and a vertical section, wherein a section close to the slag remover container has an angle of 60 ° with the axial direction.

In the above technical scheme, the fan blades are cross-shaped.

Compared with the prior art, the beneficial effects of the utility model are that:

1. therefore, the device has the functions of crushing and blowing at the same time, is directly fixed on the existing rotor degassing machine, realizes the function of dual purposes of blowing and blowing, and solves the problem that the existing device frequently has large slag remover particles to block pipelines;

2. after the use, the slag content in the aluminum liquid is reduced to the purity level below 0.2 from the original dirt with the slag content of more than 1.0 (slag content ratio) through the quantitative analysis of the K value;

3. before use, the slag inclusion waste of the die-casting finish turning product is more than 0.8% every day, and after use, the slag inclusion waste is less than 0.2% every day, so that the slag inclusion waste is obviously reduced;

4. the slag removing agent can fully react with the aluminum slag in the aluminum liquid after being crushed and come out as fine granular slag, the fine slag can well play a role in separating the aluminum slag, the problem that the large slag carries the aluminum liquid like the existing device can be solved, and the cost is greatly saved after the device is used through data analysis.
