Brief introduction of debinding furnace

The debinding furnace also known as the dewaxing furnace. It is widely used in the cemented carbide and powder metallurgy industries.

The debinding furnace (dewaxing furnace) uses heating to remove the binder in the cemented carbide expressed blank. Pre-sinter the expressed blank into a material with a certain mechanical processing strength for mechanical processing.

Application field

Special equipment for removing molding agents (such as rubber, polyethylene glycol, paraffin, etc.) from powder metallurgy products and pre-sintering the products. The results improve material quality, such as density, strength, durability, and hardness of hard metals, cermets, and other powder metallurgy materials.

1. Some products that need to be semi-inspected or processed before final sintering
2. Large products with long debinding time or extruded products with high molding content
3. Or to improve the utilization rate of pressure sintering furnaces.

Characteristics

1. The horizontal inner circle and the outer square structure are made of heat-resistant stainless steel circular liner. The square outer furnace shell is lined with an aluminum oxide fiber insulation layer, and the nickel-chromium resistance wire is hung on the outer side of the liner.
2. The front end of the furnace liner has a single door, it inserts the thermocouple into the furnace liner from the rear end, and the wax discharge pipe is led out from the middle and lower part of the back end.
3. It equips an external cooling fan to speed up the cooling speed.
4. Assemble the furnace system before shipment and thoroughly test all functions. Therefore, it can perform the assembly and commissioning at Buyer’s site within a very short time.

Functions of debinding furnace

1. Flow H2 positive pressure dewaxing method (unique uniform atmosphere control method);
2. H2 or inert gas pre-sintering;
3. Quick cooling;
4. Fully automatic control and friendly human-computer interface.
