How to Recycle Tungsten Carbide

Tungsten powder is blended with carbon (lampblack) and converted to tungsten carbide usually in induction furnaces at temperatures from 1300 to 1500° C (2400 to 2800° F). The sintering operations can be conducted in either resistance or induction type furnaces of stainless steel construction and water cooled.

CREMER Thermoprozessanlagen

Pusher furnaces – aka skillet furnaces – are represented in many processes. We at CREMER have specialised in processes under inert or reduced atmosphere. Thus, we use pusher furnace technology for reducing, sintering, carburisation, and calcination. In this process, the parts lying on charge carriers are pushed through the furnace.

Sintering in Hydrogen Atmosphere: It Punishes Refractory

Alumina formulations that work perfectly adequately in air firings – even at higher temperatures – may perform disastrously in the punishing hydrogen-atmosphere cycles of high-temperature PM sintering furnaces. Conclusion Hydrogen-atmosphere furnaces, especially those operated above about 1350°C (2462°F), are very useful for sintering many high-end alloys and ceramic/metallic compositions, but the demands placed on refractory are formidable.
