Induction Cold Crucible LEVITATION Melting of Titanium

There are different melting methods for titanium, such like vacuum consumable electric arc melting(VAR),plasma melting(PAM),electron beam melting(EBM),electroslag remelting, etc. Compare with them, the Induction Cold Crucible Levitation Melting method developed by Shenzhen Summit Levitation Metallurgical S&T Co.,Ltd has the advantages as follows:
1)Conventionally the heating process started from the titanium charge surface, however the titanium charge be heated from inside by induced current during Cold Crucible Levitation Melting technology, meanwhile the strong electromagnetic stirring provide more precise and homogenous chemical and thermal melting

2)Use Segmented Water cooled copper crucible, the copper crucible and levitation avoid the crucible contamination. That is when the cold crucible, the induction coil, the frequency, and the power level are all properly designed and matched, the liquid metal pool are pushed inward away from the interior sidewalls of the crucible, in effect, the liquid metal pool be supported and levitated by the magnetic force. 

3)Controllable vacuum or inert atmosphere
 
4)Remove HDI (High Density Inclusion) & LDI(Low Density Inclusion)
 
5)Supersonic frequency power

Shenzhen Summit Levitation Metallurgical S&T Co.,Ltd has developed Induction Cold Crucible Levitation Melting Furnace with different melting capacity like 20gram,100g,300g,1kg,3kg,5kg,
10kg,20kg,and 50kgs and with different Melting temperature 2000~3100℃, meanwhile, we combine the Induction Cold Crucible Levitation Melting process with the Centrifugal pouring to produce variable titanium precision castings. That super high quality casting can meet the aerospace industry, nuclear industry, etc.

The Induction Cold Crucible LEVITATION Melting furnace is also suitable for melting,refining,alloying for other high reactive metals,refractory metals,etc

What are Technology metal?

What are Technology metal?

Here can we say that the technology metals are those generally-rare metals that are essential for the production of 'high tech' devices and engineered systems, such as:

• The mass production of miniaturized electronics and associated devices;
• Advanced weapons systems and platforms for national defense;
• The generation of electricity using 'alternative' sources such as solar panels and wind turbines;
• The storage of electricity using cells and batteries.

There are of course numerous other uses and applications of these metals.


In the table below we list those metals that we define as ‘rare’, by defining rare as ‘produced annually in a quantity of 25,000 metric tonnes or less.’ Only the most obscure of these rare metals, such as the rare earths holmium, ytterbium, and lutetium, can still be defined as minor metals, because even today they only have minor uses since they are and will remain too rare ever to be available in sufficient quantity for mass production of a technology.

The technology metals are almost all rare metals, and they are almost all produced as byproducts of base or common metals.
The problem with the technology metals is that our supply of them, or more specifically our maximum rates of production of them, is critically dependent mostly upon our production of base metals. In the case of the rare earth metals, mined as a group, the key supply issue is the complex metallurgy of the separation of the individual rare earths from each other; for the case of lithium, a key issue is the length of time that primary concentration takes. The rare earths as a group are actually not rare, based on the admittedly arbitrary definition above, though individual rare earths certainly are.
The rare earths and lithium are today the subject of much discussion, because they have become the most visible technology metals.  The definition of a rare metal is somewhat fluid; a few of today’s rare metals may not always be so. Lithium, for example, is on the cusp of being struck from the list of rare metals, because of its use in electrical storage. But it has turned out that once a minor metal becomes a technology metal, it will never again be a minor metal.
 
Shenzhen Summit Levitation Metallurgical S&T Co., Ltd is focus on research and develop levitation induction melting. Our Levitation Induction Melting Equipment is ideal for those technology metals refining,alloying,casting.

Principle of The Levitation Melting

 

Levitation Metallurgical Equipment(Induction Cold Crucible Levitation Melting Furance)uses a Water Cooled Crucible(Cold Crucible) that does not react with the melt under vacuum or inert atmosphere in an induction coils, the electromagnetic field will levitate the liquid metal pool during melting,therefore no crucible contamination,no chemical cross contamination, also eliminate gas contamination. It is an ideal melting,refining,alloying and casting equipment for reactive metals and alloys, refractory metals and alloys, ultrapure metals, precious metals and alloys, and other metals.  

Principle: 

The Electromagnetic field produced by the induction coil, that passes through the cold crucible which is made up of water-cooled segments to produce the induced eddy current, the eddy current produce heat and melt the metal, meanwhile, the eddy interact with magnetic line of force so that produce their vertical electromagnetic force which support and levitate the molten metal pool.

What is Levitation Metallurgy?

Levitation Metallurgy refers to the material production and processing technology which uses the levitation melting as core technology and combined with casting, directional solidification, zone refining,distillation, etc,it is an ideal technology which levitates the liquid metal pool during melt under the vacuum or inert atmosphere,no crucible contamination.

Levitation Metallurgy has a wide application as follows:

1. Reactive Metals and Alloys production
e.g RE metals and alloys,Ti & Ti alloys,Uranium-earth,Alkaline-earth metals and alloys

2. Ultrapure Metals and Alloys production
e.g.ultrapure sputtering target and coating materials,Solar polycrystalline silicon, Ultrapure metal 6N~8N;

3. High Grade Alloys and Intermetallic compound production
e.g.Intermetallic compound production,GMM,Functional material,Mirco-alloy materials;

4. Refractory Metals and Alloys production
e.g.The melting point between 2000℃~3000℃ like Cr、Zr、Hf、V、Nb、Mo、Ta、Pt、Rh、Ir,and alloys,etc

5. Material Research
Except to produce the higher grade material with high purity,precise and homogenized composition,no contamination or other elements interference,also create the better production condition for alloys and intermetallic compounds.
