I'd like to smelt 104 aluminium alloy by medium frequency furnace. What should I pay attention to? Please point it out, thank you!
I can not decide which is good. I just want to talk about the smelting methods of some nonferrous alloys of my own experience. (1) casting, casting, tin bronze, 5-5-5, fused magnesia, medium frequency furnace smelting. Carbon contamination of aluminum alloy and copper alloy
Don't know what is your crucible material medium frequency furnace, if using graphite crucible, graphite as easily broken and easy to absorb moisture, must be handled with care to avoid the collision, but must be in use before the slow heating and drying, until the crucible to dark red, check no cracks can be put into the molten alloy. If the iron crucible, the Aluminum Alloy are strictly limited, so the iron, iron crucible, Tieshao, ladle, the tool must be coated with paint, paint is selling goods, components do not know, iron crucible and apparatus must also be preheated, exclusion of moisture. In addition, do not know you are refining aluminum ingot or making ah Aluminum Alloy parts, if the production parts should pay attention to defects of oxidation, slag and coarse grain, I am afraid that refining, refining agent are also ready to sell goods, how can read the instructions. Especially when smelting Caution!, preventing aluminum liquid splash, including many contents, such as inspection and testing, there is not much to say, the main note in the smelting process I thought so much, typing is slow, very hard ah, hey. Hope to be of some help to you.
If the intermediate frequency furnace may smelt, pays attention to the coating, will cross several furnaces to have to paint once.The alloy after melting also needs to be transferred to the heat preservation furnace, and then the slag removal and degassing are carried out. Because of the rotation of the aluminum liquid in the intermediate frequency furnace, the separation effect of slag inclusion is very poor.
