Detailed Description
The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.
An A356 aluminum liquid environment-friendly clean treatment method comprises the following steps:
s10, keeping the aluminum liquid standing for a time period t 1;
s20, inserting a filter screen into the aluminum liquid;
s30, keeping the aluminum liquid standing for a time period t 2;
s40, lifting the filter screen from the aluminum liquid;
s50, sealing and covering the top opening of the heat preservation furnace;
and S60, filling argon into the internal space of the top opening of the heat preservation furnace top.
In some embodiments, t1 is 10 ± 2 minutes.
In some embodiments, the filter screen is in a flat plate shape, and the filter screen is kept inclined relative to the liquid level of the aluminum liquid during the process of inserting the filter screen into the aluminum liquid, and the inserting direction of the filter screen is parallel to the filter screen.
In some embodiments, the filter screen is inclined at an angle of 25 degrees relative to the liquid level of the aluminum liquid during the insertion of the filter screen into the aluminum liquid.
In some embodiments, t2 is 3 ± 1 minute.
In some embodiments, during the process of lifting the filter screen from the aluminum liquid, the filter screen and the surface of the aluminum liquid are kept relatively inclined, and the lifting direction of the filter screen is vertical to the liquid level of the aluminum liquid.
In some embodiments, during the process of lifting the filter screen from the aluminum liquid, the angle of inclination of the filter screen relative to the liquid surface of the aluminum liquid is 10 degrees.
