TCC – Vacuum Continuous Casting Machines
TCC Vacuum Continuous Casting machines have been design with the most up-to-date technologies to give you semi-finished products with the best quality and in the shortest time.
With only one machine, you will be able to obtain the semi-finished product you desire, such as wires, sheets or tubes.
TCC machines are equipped with Gas Wash Purge procedure which removes oxygen with the vacuum pump and fills back the melting chamber with inert gas, preventing the oxidation of the alloy in a very fast and efficient way.
Medium frequency induction heating stirs the melted alloy and leads to a perfect homogeneity, while the temperature is constantly monitored by two independent temperature controls.
As on option, it is possible to have an additional vacuum loading chamber, positioned on top of the cover with automatic crucible feeding mechanism, for continuous production.
During drawing, the temperature of the die is constantly monitored to obtain always the best density and quality in the semi-finished products. In addition, there are two independent temperature controls for preventing liquid metal leakage, one of them with an optical pyrometer aiming directly on the bar coming out from the die.
The drawing unit can also be equipped with an extra induction generator, which allows to restart the cycle after the production shutdown.
Pulling unit is equipped with devices for automatic detection of slippage phenomena between the roller and the semi-finished product. Another specific device will also detects the end of the cycle, when the bar reaches its end.
To reduce the risk of oxidation during drawing, the semi-finished products are under a constant inert gas flushing as they come out of the die.
In addition, when a quicker cooling is required, semi-finished products can be cooled down by a direct water sprinkle aiming on their profile.
Hydraulic cutting on the run is available on request, with automatic and programmable measurement of the profile length.
