Refining Tank For Aluminum Melting and Casting
Refining operation
1. Open the lid of the duster tank, and press 1.5 kg tons of aluminum. Add the required refining flux to the duster tank.
2. Clean up the spilled micro-flux, install the cover and tighten it.
3. Open the nitrogen bottle, turn the regulating valve slightly to make the gauge pressure reach the required value, and nitrogen gas should be ejected from the end of the refining tube.
4. Turn on the power, the red light is high. Push the switch, the green light is on, and the refining agent should be sprayed out from the end of the refining tube.
5. Insert the refining tube into the molten aluminum pool, and the outlet of the refining tube moves back and forth along the bottom of the furnace until the refining agent is sprayed out.
6. Continue to pass nitrogen for 1-2 minutes, then take out the refining tube and stop supplying nitrogen.
Precautions
1. The powder spraying machine should be placed in a position favorable for jet refining, and the distance from the furnace should be shortened as much as possible to reduce pressure head loss.
2. After the refining agent is loaded into the material tank, the duster should not be moved to avoid blocking the refining agent.
3. During storage and use, strictly prevent the refining tube from bending, which will cause blockage.
4. During the refining process, strictly prevent the outlet of the refining tube from contacting the furnace bottom and furnace wall. If contact occurs, it will easily cause blockage.
5. When the refining agent is wet, it is easy to cause blockage. At this time, the refining agent should be dried and sieved before use.
6. When there is residual aluminum and residue in the refining tube, it should be cleaned up to ensure the smooth flow of the refining tube.
