High temperature pressure sintering degreasing integrated furnace
The high temperature pressure sintering and degreasing integrated furnace combines the positive and negative pressure degreasing, atmosphere sintering, vacuum sintering and pressure sintering processes. It is used for the sintering treatment of cemented carbide, cermet and other products. It can work in the vacuum, AR / H2 / CH4 gas environment, the temperature as high as 1700 ℃ and the pressure as high as 100bar. Uniform heat field, advanced gas field distribution and precise temperature control curve ensure the high quality and qualified rate of products. Up to 98% of the dewaxing collection rate (Paraffin), to ensure full recovery of paraffin, and significantly reduce the pollution of vacuum pump oil, effectively extend the maintenance cycle of vacuum pump.
