Combi-High-Temperature Furnaces for Debinding and Sintering in One Process

For combined debinding and sintering processes with sintering temperatures up to 1750 °C, the high-temperature furnaces will be equipped with a passive safety system which ensures a safe operation by monitoring all functions relevant during debinding . In addition, fresh air is supplied to the furnace chamber in a controlled way to reliably prevent a combustible atmosphere forming inside the furnace by diluting the binder gases.

The smaller furnace models can be equipped with the DB50 laboratory debinding package, which is designed for small binder amounts and low vaporization rates. In the basic design, the DB100 debinding package is available for larger furnaces. With this debinding package, preheated fresh air is introduced so that the furnace is operated with overpressure during the debinding phase.

The DB200 debinding package is the ideal solution for high-temperature furnaces used in production processes. With this safety system, the furnace has a fresh air preheater and the preheated air is blown into the furnace horizontally 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 furnaces HT, however:

• Stainless steel exhaust hood as interface to the customer's extraction system (DB200 option: separate removal of exhaust gases during debinding)
• Controller with touch operation P570 (50 programs each with 40 segments) for models HT 16.. - HT 40..
• From model HT 64..: HiProSystems H1700, including Siemens PLC control system and 7" touchpanel as operating interface 

Debinding Package DB50
