What is Graphite heater / graphite heating element?

Graphite heater / graphite heating elements are used frequently in high-temperature vacuum sintering furnaces and are also widely used. In high temperature furnaces, graphite parts can be used in vacuum sintering furnaces, graphitization furnaces, vacuum brazing furnaces, intermediate frequency vacuum induction furnaces, high temperature heat treatment furnaces, etc.

The graphite heating element is the core part of the high-temperature vacuum sintering furnace, and its quality directly affects the performance and operating cost of the high-temperature vacuum sintering furnace. The design of the thermal field of graphite heating element is varied, which specific design choice is mainly based on the specific analysis of the process flow. The graphite heating element of most high-temperature vacuum sintering furnaces includes four main components: heaters and their connecting parts, heat insulation parts (or reflection screens), thermal field supporting parts, and workpiece carrying hearth. These accessories often need to be replaced regularly due to material problems or time problems.


Graphite products are divided into five categories:

1, graphite heating parts ------ graphite heating parts
2, graphitel insulation parts ------- furnace bottom graphite plate, graphite chamber, graphite pipe, graphite disc
