Embodiment 1
[0027] Step 1: Cut the waste foamed magnesium into 20mm×20mm×10mm blocks. The cut blocks are ultrasonically oscillated with acetone for 20 minutes, then cleaned with alcohol, and finally dried with a hair dryer. Weigh 500g of dried waste foamed magnesium ;
[0028] Step 2: Preheat the crucible to 400°C in a resistance furnace, then put the waste magnesium foam weighed in the first step into the preheated crucible, raise the temperature to 650°C, and feed the protective gas at the same time, (selected protective gas The volume ratio in air:CO 2 :C 2 h 2 f 4=375:124:1; the composition of the shielding gas in the fourth step below is the same), and the waste foamed magnesium is melted and then incubated for 5min;
[0029] Step 3: Stop passing the protective gas, use the rotary nozzle to inject argon gas into the melt, the ventilation speed is 5L / min, the rotation speed of the nozzle is 240r / min, the time is 3min, and then stand still for 8min, and then remove the melt inclus...
Embodiment 2
[0037] Step 1: Cut waste magnesium foam into blocks of 10mm×10mm×10mm. The cut blocks are ultrasonically oscillated with acetone for 30 minutes, then cleaned with alcohol, and finally dried with a hair dryer. Weigh 500g of dried waste magnesium foam ;
[0038] Step 2: Preheat the crucible to 450°C in a resistance furnace, then put the waste magnesium foam weighed in the first step into the preheated crucible, raise the temperature to 680°C, and feed the protective gas at the same time, (selected protective gas The volume ratio of the air:CO 2 :C 2 h 2 f 4 =150:49:1, the composition of the shielding gas in the fourth step below is the same) after the waste foamed magnesium is melted, it is kept for 10min;
[0039] Step 3: Stop passing the protective gas, use the rotary nozzle to inject argon gas into the melt, the ventilation speed is 8L / min, the rotation speed of the nozzle is 360r / min, the time is 5min, and then stand still for 10min, and then remove the melt inclusions ...
