This is produced by proportionally mixing several salt compounds with the use of special processing techniques.  Carried by nitrogen or argon and blown through the powder blower to the inner of the aluminum melt, which will be purified by both gases and the refining granules. Widely used in the aluminum processing industry.
 
Properties: Grey white granule, 2.5kg/pack or upon request.
 
Applicable to: Refining pure aluminum and general aluminum alloys.
 
Processing Temperature: 700℃～760℃
 
Recommended Dosage:  Add this equal to 0.1～0.4% of the weight of the aluminum melt.
 
Features and Benefits:
1. Being a combination of gas refining and flux refining, it is very effective in degassing.

2. It requires a small dosage making it easier to use. Additionally, it can also reduce the operators’ workloads.

3. It has high utilization rate for both degassing and deslagging.

4. No mist, dust or odor is generated during the refining process due to compliance with environmental protection requirements.
 
Instructions for use:
Within the required temperature for refining, feed the refining granules into the tank of the powder blower and seal the cover tight. Connect the powder blower to nitrogen (at a pressure of 1.2～1.8kg/cm²). Turn on the switch at the lower part of the refining tank. Insert the iron pipe into the aluminum melt to 3/4 of its depth as soon as the refining granule is blown out, and move the iron pipe horizontally two to three times without contacting the smelter walls in order to avoid a clogging. Blow all refining granules during the refining process (about 10~15 minutes for 6~20 tons). Pull the iron pipe out of the aluminum melt and disconnect nitrogen input.
 
Cautions:
A. Control the blowing rate for powder by using the switch at the lower part of the refining tank and ensure that there is refining granule coming out from the powder blower during the entire refining process.
B. Control the level of aluminum melt waves by regulating the nitrogen pressure. Try to minimize the level of aluminum melt waves, preferably below 15cm.
 
Packaging and Storage:
Pack in plastic bags with corrugated boxes or woven bags as secondary packaging (20kg or 25kg per box). Store with caution in a dry place and avoid damp.
