 High vacuum die casting - Patent 6070643
The melting crucible 54 may be a conventional induction skull crucible comprising copper segements in which a charge of solid metal or alloy to be die cast is charged via vacuum port 40b and melted by energization of induction coils 56 disposed about the crucible in conventional manner in the chamber 40.
The crucible 54 can be tilted by rotation about crucible trunnions T using a conventional hydraulic, electrical or other actuator (not shown) disposed outside the vacuum chamber 40 and connected to the crucible by a suitable vacuum sealed linkage extending from the actuator to the crucible.
The crucible is tilted to pour the molten metal or alloy charge into the melt-receving vessel 52, which is communicated to the shot sleeve 24 via opening 58 in the shot sleeve wall.

 THE MAKING OF A BRONZE SCULPTURE:
"OLD WARRIOR"
As the bronze is heating, the ceramic shells are replaced in the kiln and heated/dried prior to the pour.
Once the bronze is brought up to the right temperature, the crucible, containing the molten bronze, is removed with a large pair of tongs, operated by two people.
Using a torch to heat the bronze and chemical colouring agents, the skull is given a patina or colour.

During a sacred ceremony, the elaborately decorated lid was removed and the skull – perhaps lined in gold – became a crucible.
Inside, symbols of ordinary life were placed, heated, and transformed as part of an elaborate ritual enacted to help the initiates visualize the conversion of ordinary life and death into the path of enlightenment.
This skull, given the elaborate mount of costly materials, undoubtedly belonged to a high-ranking lama, whose spiritual status lent special importance to this ritual object.

In a conventional one piece copper crucible the magnetic field generated by the field current in the heating coil is cancelled out by the magnetic field associated with the induced current in the crucible.
While the conventional VAR process demands the use of a custom made electrode, sized to fit the crucible, the Taramm process is able to use forged or rolled premium quality off cut, material which is a fraction of the cost of the VAR electrode.
A new crucible, redesigned to generate full levitation of the charge and with an innovative `pour' capability, has been developed and is awaiting a patent.

 Cubic Zirconia - Background, Raw Materials, The Manufacturing, Quality Control
A seed crystal is attached to one end of a rotating rod, the rod is lowered into the crucible until the seed just touches the melt, and then the rod is slowly withdrawn.
Because water cools the walls of the skull, the powdered materials next to the walls do not melt, and the molten material is contained within a shell of unmelted material.
In the skull melt method to grow cubic zirconia, a hollow-walled copper cup is filled with powdered ingredients and heated by radio frequency induction until the powders melt.

 Cold crucible induction furnace with eddy current damping patent invention   (Site not responding. Last check: 2007-10-13)
After removal of the liquid metal product from the crucible, the skull can be left in place for a subsequent melt, or removed from the crucible, as desired.
Further the skull may be reduced in overall volume, so that parts of the liquid melt formerly contained within the skull can come into contact with the wall of the crucible, which greatly increases the heat loss from the liquid metal.
By reducing the metal flow velocity, such damping reduces the turbulence in the liquid metal near the bottom of the cold crucible, thereby reducing the heat convectively transferred from the liquid metal into the skull; thereby permitting significantly increased superheat for a given power input.

 Melting and Pouring of the Reactive Metals
A titanium charge is placed in the crucible with granular calcium fluoride added to act as an electrical insulator between the titanium and the crucible to prevent arcing and crucible damage.
Here is where the segmented crucible becomes important, because if it weren’t nearly all the field generated by the induction coil would dissipate before it could melt the charge.
Named for the "skull" of material that lines the crucible after each pour, ISM is purported to offer several advantages over other reactive metal melting and casting techniques.

The crucible is filled with the powdered chemicals necessary to grow a specific crystal and is lowered slowly through a furnace.
The small, pointed end of the cone cools first because it is the first part of the crucible that moves from the hottest part of the furnace into cooler regions and it is the first part to emerge from the furnace.
As the crucible cools, the molten materials solidify, hopefully in a single crystal, in the point of the crucible.

Cubic zirconia is made using a radio-frequency "skull crucible" system, a specialized melt process.
Skull melting is a type of super-hot melt process used to produce the most widely accepted diamond imitation: cubic zirconia (CZ).
Zirconium oxide, the main component in cubic zirconia has a extremely high melting point (approximately 4980'F), Conventional melt crucibles (which have lower melting points) cannot be used.

Under these extreme temperatures, conventional melting vessels or crucible, do not withstand the heat and a ‘skull crucible’ system is employed whereby the melting zirconia powder actually creates its own melting vessel during its manufacture.
This ‘skull crucible’ is an apparatus rather like a cup-shaped circle of copper fingers filled with water and kept cool by internal plumbing.
During this shell-making process, the zirconia and stabilizing oxide is added to the ‘skull’ to the desired level.

(Nassau, 1981) This requires such high heat that a special radio frequency "skull crucible" must be used to melt the zirconia powder.
