When processing cemented carbide, there are a few considerations you need to understand to use the proper sintering equipment. One of the biggest factors is the actual material; what is the colbalt content level of the processed material?
In this best of the web article, walk through the steps of dewaxing, sintering for appropriate densification, and the processing temperatures that are required for sintering cemented carbide.
An Excerpt:
“Other than mechanical stresses due to the differential pressure between inside and ambient pressure outside the furnace, operating at relatively high temperatures with high pressure of gas would lead to significant dissipations of heat to the external environment. This is not only anti-economic from an efficiency point of view, but could also compromise the structural integrity of the water-cooled steel vessel of the furnace by overheating it.”
