Graphite products have been increasingly widely used in vacuum furnaces, not only to manufacture heating elements and heat insulation screens of vacuum furnaces, but also to manufacture force-bearing structural parts such as brackets, material trays, guide rails, bolts, bearings, fan blades, etc. The application of graphite in vacuum furnaces greatly simplifies the design and manufacture of vacuum furnaces, reduces the consumption of metals such as tungsten, molybdenum, tantalum, stainless steel, etc., reduces costs, improves certain properties of vacuum furnaces and expands the scope of use of vacuum furnaces.

Graphite has good vacuum performance, thermal conductivity, small thermal expansion coefficient, increased strength with temperature increase, good processing technology, etc., coupled with low cost, so it is a high-quality and inexpensive material.
