It is standby.
Background technology
Induction Melting Technology is a kind of advanced melting means, and it eliminates in fusion process atmosphere and heating source to furnace charge
Pollution.It is especially vivaciously golden in melting but in general process for vacuum induction smelting can not prevent the reaction between furnace charge and crucible
When category or high purity metal, this influence is very serious.There is a kind of more advanced cold crucible vacuum induction in last century end
Melting technique.It is that one kind utilizes cold-crucible（Predominantly fine copper, also useful other alloys）To carry out vacuum induction melting
Method.Such a method can exclude pollution of the crucible to furnace charge completely.
Cold crucible induction melting device mainly has three kinds of casting modes：Topple over casting (tilt-tapping) technology, uphill casting
(bottom-tapping) technology, the uphill casting technology of floating type (lavitation type) cold crucible.
Topple over foundry engieering advantage be it is simple in construction be easy to implement, problem is, melt is the same as crucible wall when verting
Contact area increases, and scull is significantly grown up, and the melt amount cast out is reduced.So casting should be as fast (generally at 3 seconds as possible
Within).In addition, casting is just grown up rapidly once interrupting scull, need crucible going back to fusing scull in situ to recover casting,
Repeatedly.
The problem of uphill casting technology of floating type cold crucible, is that the very big melt quality of suspension is had any problem, and only suspends at present
Melting 5kg device, industrialized scale can't to be used for.
Therefore, uphill casting technology has the advantage of application.But its structure and technique are extremely complex.Require further study.
