The electrically heated tilting furnaces of the KC 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
SiC-Crucible
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
Electro-hydraulic tilting device with safe two-hand operation on the furnace
Uniform and precise pouring due to optimum pivot point
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

Equipaggiamento aggiuntivo

Additional heating transformers provide for significant reduction of the connected load
Safety fence
Work platform for simplified loading
Process control and documentation via Nabertherm Control Center (NCC) for monitoring, documentation and control
