The furnace for continuous casting of metals and alloys of precious metals is designed to provide the user strips of product with a definite shape (square, rectangle, round, tube, strips, other …) to be sent to subsequent machining drawing, rolling or other.

The continuous casting furnace is mainly composed of two overlapping zones, a zone of melting metals and an area of controlled solidification of the same in a definite form.

MELTING ZONE
The melting of the metal is done in a graphite crucible by electromagnetic induction . The variable magnetic field , generated by the frequency converter installed on the machine, determines the formation of eddy currents in the graphite crucible and the metal itself . The resulting Joule heat causes a temperature rising up to exceed the melting point of the metal or metal alloy .

AREA OF CONTROLLED SOLIDIFICATION
At the bottom of the crucible is coupled a die of the same material (graphite) that has a cavity with the desired shape ( square, rectangle , round, pipe, strips, other …). From this chain will be released on metal in the form chosen .
The graphite die, removable and interchangeable , is the real bottom of the crucible and once melted, the molten metal begins to penetrate into the die assuming the shape of the cavity.
Advancement of the metallic strip is provided by a towing system based on knurled rollers motorized.

• All functions are controlled by microprocessor
• Digital control of power, casting speed, crucible and die temperature
• Medium frequency converter guarantees high efficiency
• Self-diagnosis with alarm and warning messages
• Temperature control of the crucible and die via independent thermocouples
• Metal oxidation avoidance system
