Description
El deagglomerated vacuum oven is used primarily for debinding tungsten heavy alloy, molybdenum alloy and cemented carbide materials. It can remove the binders as polyethylene glycol (PEG), paraffin and rubber. The vacuum tube furnace debinding process also applies to the bar extrusion and parts presión.
Technical characteristics
1. The oven has a special structure and design thermal zone of thermal elements, which are characterized by uniformity temperatura.
2. The special design of the muffle debinding is adopted with a good seal and complete removal of the binder, thus avoiding contamination of the inner components.
3. The vacuum oven deagglomerated has functions slow vacuum, vacuum presintered, deagglomerated under negative pressure, deagglomerated TOWAC and deagglomerated under pressure positiva.
4. The oven structure and adopts advanced refractory materials, characterized by good performance of insulation and heat absorption baja.
5. It is operable via touch screen central control and PLC (Programmable Logic Control), which makes operation simple and confiable.
6. The oven has the fault alarm functions overtemperature and pressure, automatic pressure mechanical protection and blocking, thus forming a highly secure oven.
7. The vacuum furnace debinding operation has the remote control, remote diagnostics and remote malfunction program update functions.
