Smokeless Refining Agent

Product name：Smokeless Refining Agent

Detailed introduction：

Principle
This product is smokeless environmental protection refining agent ,By use of powder spraying machine,spray powder refining flux into aluminium melt bath with high purity nitrogen,Under the combined effect of dispersed tiny nitrogen bubble and flux,it will eliminate the entrapped slag and hydrogen in aluminium liquid.

Use method
Add refining flux of requires amount into refining tank and cover it properly,turn on the switch of refining tank and connect nitrogen gas ,When furnace flux is spraying out of refining iron tube ,insert it into the furnace and move all around inside evenly for 2or 3 times. When powder inside the tank is sprayed completely,first draw out the refining tube out of aluminium liquid, and then switch off nitrogen gas.

Technical parameters
1.Refining temperature:700℃~740℃
2.Refining time :8~15 minutes (6~20ton furnace)
3.Nitrogen pressure:1.2~1.8kg/mm2
4.Use level 1~3kg for one ton aluminium

Precautions
1.The refining time shall be extended along with increase of aluminium melting volume.
2.The powder feeding rate can be controlled by adjusting switch on the bottom of refining tank,Generally ,there shall be powder spraying out within the rang of refining time .
3.The end of refining tube shall be inserted into the furnace by 2/3of the aluminium liquid depth ,The tube shall be moved to left and right side,The furnace wall and bottom shall not be touched to prevent from clogging of tube.
4.The turbulence height of aluminium liquid shall be controlled by nitrogen pressure ,Under the premise of preventing from cllogging of tube ,the higher turbulence is acceptable,It is better to control below 15cm.

Packaging and storage
It is 2kg for each package and 20kg for each box,which shall be stored in a dry and ventilated place, The storage period is one year if plastic bag are not damaged.It can be further used when it is ground into powder and dried under the temperature of 100℃
