Combi-High-Temperature Top Hat Furnaces or Bottom Loading Furnaces for Debinding and Sintering in One Process
In the basic design, the DB100 debinding package is available for the top hat and bottom loading furnaces.
Function and equipment
The combi high-temperature top hat and bottom loading furnaces are designed for debinding and sintering in one process with sintering temperatures up to 1750 °C. Equipped with a passive safety system, all functions relevant for debinding processes are monitored to ensure safe operation of the furnace. Also as part of the safety package, the furnace atmosphere is diluted with fresh air to prevent forming of a combustible atmosphere by the exhaust gases evaporating from the charge during debinding.
In the basic design, the DB100 debinding package is available for the top hat and bottom loading furnaces. With this debinding package, preheated fresh air is blown in and the furnace is operated with overpressure during the debinding phase.
The DB200 debinding package is recommended as a solution for production. With this safety system, the furnace has a fresh air preheater and the preheated air is blown into the furnace through perforated air inlet tubes. During debinding, the exhaust gases are discharged from the furnace via a separate outlet with exhaust gas fan. The volume flows of fresh air and exhaust gas are controlled so that a slight negative pressure is always maintained in the furnace chamber during debinding.
Like high-temperature top hat and bottom loading furnaces HT .. LB/LT, however:
- Motor-driven exhaust air flap in the furnace roof
- Stainless steel exhaust hood as interface to the customer's extraction system (DB200 option: separate removal of exhaust gases during debinding)
- HiProSystems H1700, including Siemens PLC control system and 7" touchpanel as operating interface
Debinding Package DB100
- Basic model for safe debinding with small amounts of binder
- Fresh air fan and fresh air preheater
- Exhaust gas and exhaust air discharged via one outlet with a motor-driven flap in an exhaust hood
- Performance of the debinding package customized to the process requirements
Debinding Package DB200
- Professional solution for large amounts of binder and changing debinding processes in everyday production
- Fresh air fan, fresh air preheater and monitoring of fresh air and exhaust gas flow rates
- Separate discharge of exhaust gases during debinding and exhaust air during cooling via separate outlets with motor-driven flaps
- Extendable with catalytic or thermal post combustion for a single furnace or alternating operation with two furnaces
- Performance of the debinding package customized to the process requirements
