功能与设备
The electrically heated bale-out furnaces of the TC product lines are characterized by a higher maximal temperature than achievable with wire heated melting furnaces. This allows for processing of demanding copper alloys such as aluminum bronze. These furnaces are designed for permanent operation at working temperatures.
- Melt temperatures up to 1320 °C
- Symmetrical heating via powerful SiC rods
- Simple exchange of individual heating elements
- Heat operation by thyistors in phase-angle mode with performance control:
- The resistance of the SiC rods changes with temperature and age. Performance control ensures constant power of heating irrespective to the condition of the heating elements.
- Multi-layer insulation for optimum energy efficiency and low external wall temperatures
- Emergency outlet for safe draining of the melt in case of crucible breakage
- Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
- Over-temperature limiter in furnace chamber for protection against overheating. The limiter switches the heating off when the set limit temperature is reached, and only switches it back on after the temperature has fallen again.
- Low-maintenance furnace chamber control with temperature measurement behind the crucible
- Defined application within the constraints of the operating instructions
