Dewaxing & Sintering Integrated Furnace introduction:

The dewaxing & sintering integrated furnace refers to the process of dewaxing, pre-sintering, high-temperature vacuum/atmosphere sintering, and rapid cooling of the furnace body in the same furnace.

Application:

The pressed alloy powder is always heated to a certain temperature (sintering temperature) in the sintering furnace and kept for a certain time (holding time). Then, cool down to obtain the desired properties of the alloy material.

Material application:

Cemented carbide
Hard metals
Cermets
PM-special alloys
Technical ceramics

Dewaxing & Sintering Integrated Furnace function:

Dewaxing/ debinding for all conventional binders: Vacuum dewaxing, Negative (Ar gas) differential pressure dewaxing, H2 gas micro-positive pressure dewaxing (with flowing H2 burn-off system)

Sintering: Under vacuum sintering, with inert and reactive gases sintering (atmosphere sintering)

Features of the Integrated Furnace:

• Efficient dewaxing and wax collection system, the dewaxing rate is over 95%.
  The system directs the forming agent (paraffin) removed from the workpiece out of the furnace. And collect the forming agent as much as possible to avoid the pollution of the forming agent to the furnace and vacuum system.
• Uniform temperature control
  It uses three independently and reasonably distributed heaters to ensure temperature uniformity in the heating zone. Equipped with a heater circuit insulation resistance detection system to detect heating system failures in time.
• Precise Control and Measurement
  Adopt high-precision measurement and control technology to control pressure, temperature, and flow parameters precisely. It has a perfect and comprehensive data record backup function. It can realize remote control, remote fault diagnosis, and system maintenance operation.
• Rapid cooling, shortening the production cycle
  To improve the cooling efficiency of the furnace, a special heat exchanger and a special cooling fan are installed on the rear door.
