機能と設備
The electrically heated N ../WAX furnaces are particularly suitable for dewaxing of ceramic molds below the flash point of the wax and subsequent firing. The electrically heated chamber furnaces have a heated outlet in the bottom of the furnace chamber, formed as a funnel with the discharge near the center of the furnace. The drain pan on the furnace bottom is covered with stainless steel grids, which provide for an even charging surface for the molds and can be removed for cleaning. The molten wax is collected in a sealed stainless steel container with a removable drawer below the furnace. After the dewaxing process is completed, the furnace continues heating to sinter the molds. Fresh air inlets in the bottom area and a motorized exhaust air flap ensure good ventilation of the furnace chamber during the process. The resulting exhaust air is discharged via the exhaust hood and further customer-provided piping.
- Tmax 850 °C
- Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
- 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.
- Chamber furnace with wide-opening swinging door
- Fresh air inlets in the bottom for continuous air exchange
- Motorized exhaust air flap in the furnace ceiling with exhaust hood for connection to customer provided ductwork
- Four side heating with freely radiating heating elements on ceramic support tubes
- Heated outlet in the furnace bottom, controlled and monitored by a separate controller with a temperature working range of min. 200 °C - max. 300 °C, to safely prevent the escaping wax from solidifying
- The furnace heating is released after a preset temperature has been reached in the drainage to protect the wax outlet from clogging
- Stainless steel floor pan with grid bottom for level loading
- Rugged self-supporting, vaulted arch construction
- Over-temperature limiter for the furnace chamber, which must be set below the flash point of the wax and prevents the wax from igniting during the melting process. The duration of the dewaxing process is specified by the customer. After this time, the over-temperature limiter is deactivated so that the furnace can continue with the sintering process.
- Controller with touch operation B500 (5 programs with each 4 segments)
- Defined application within the constraints of the operating instructions
