Why is there a lot of glue after the aluminium ingot is melted?
Maybe the temperature is not high enough;
You were being set up (ingot tundish ash, suggest that you get some cut sampling, look at the middle consistency). It is a greater loss, only the ash picked up, and then put the iron pot with sodium nitrate, pulverized coal stir, the question raised by this al DNA. The most after I have a advice, please do not use zinc chloride, it is toxic, a few days down near all the plants will die, will seriously affect the health!
Add zinc chloride to the surface of the aluminum and stir it up to separate the aluminum and the ash
