CONTINUOUS CASTING FURNACES - FIM/CC

Converter

Our frequency conversion system allows to reach an elevated electrical yield, and consequently reduce the consumption of electrical energy, while maintaining constant the production.

The modular construction of the electrical circuit simplifies the maintenance procedures and guarantees a high level of reliability, even under the most difficult operating conditions.

Crucible and Die

Made of high-quality isostatic graphite, the die is manufactured to produce the profile needed for your production: wire, plate or tube of the desired dimensions. The furnace can be equipped to produce also special shapes.

Secondary cooling system

Made of graphite positioned below the die. This guarantee a perfect homogeneous cooling and helps prevent oxidation. The second cooling is necessary in case of use of alloy with high content of copper.

Direct water cooling by sprinkles.

The direct water on the profile guarantees an extra cooling and, at the same time, a deoxidizing treatment.

Moreover, the profile will be annealed, making it easier to be worked in the next production steps (rolling mill, etc.).

The water is recovered by a draining system.

Pulling roller

The powerful driving unit drives the profile following the programming that adjusts the speed, the pull length, the drawing length, etc.

Inert gas injectors

The inert gas injection both on the top of the crucible and on the end of the die creates an oxygen-free chamber, preventing the oxidation of the metal.

The absence of oxygen is important to guarantee a longer life of the graphite crucible and die, thus reducing the running costs.

Thermocouple for the temperature control of crucible and of the die

The crucible thermocouple acts directly upon the converter, thermo-regulating the temperature to keep it at the level selected by the operator, while the die thermocouple modifies the flow rate of the cooling water in order to guarantee the correct solidification of the metal.

Touch-screen control

To set all parameters (power, temperature, etc), to save the working recipes and to see the alarms and the operations advised to solve the problem.

 MAIN ADVANTAGES

• High efficiency due to medium frequency induction converter.
• Self-diagnostics with failure messages.
• System to prevent oxidation of the metal.
• Fast melting of the metal with perfect homogeneity, thanks to the convective currents that are generated inside the crucible.
• No metal loss.
• High malleability of the profile for an easy working without annealing
• Quick interchangeability of the crucible and die.
• Safety protection for containing accidental leaks.
