TUNNEL FURNACE FOR GOLD AND SILVER BARS PRODUCTION - T-BARMASTER

This system achieves high efficiency levels and reduces metal losses.

Using the proper furnace model, it is possible to obtain more formats - from 1 ounce to 1000 Ag ounces - with special graphite crucibles designed on specific customer request.

How does it work?

In the T-Barmaster™ furnace, the ingot mold is inserted into the melting area by a mechanical pusher. Due to induction heating, metal melts and turns from solid state (grains) into liquid state (molten metal).

Melting occurs according to the parameters set by operators, as well as the metal type and the furnace version which is being used. Thanks to the user interface, operators can easily control the process and reach the desired quality.

Once the time set for melting expires, the ingot mold containing molten metal is pushed on a solidification plate with circulating cooling water: during this step no mechanical lifts or chemical additives are used. The solidification step is essential to obtain ingots with perfect finishing; thanks to an optical pyrometer, it can be handled by operators with great accuracy.

Now the ingot is pushed towards the cooling tunnel and through the outlet Pinch™ Valve.

KEY FEATURES

• The patented technology called Pinch Valves™, placed at both ends of the tunnel, ensures a perfect sealing: as a matter of fact, this system with pneumatic valves keeps oxygen outside the tunnel, maintaining an inert atmosphere and drastically reducing gas -usually nitrogen - consumption. Graphite consumables last longer and do not deteriorate due to oxidation.
• This furnace needs to be connected to a duly sized water refrigeration installation (T-Chiller).
• No explosive gases or open flames, therefore operators work in a safer and controlled area in ideal environmental conditions
• Metal does not undergo significant loss, that means that the ingot has the same weight as the grains put in each ingot mold
• No emission of harmful fumes or electromagnetic fields: an important advantage for operators' health and significant cost savings
• According to the chosen automation degree, operators act as simple processing supervisors and do not necessarily need to be always present.

ADVANTAGES

• high productivity
• high product quality
• safety for the operator
