Graphite Parts for High temperature vacuum furnace

Vacuum furnace graphite parts have been widely used in vacuum furnaces, not only for manufacturing heating elements and heat shields of vacuum furnaces, but also for manufacturing mechanical structures such as brackets, pallets, guides, bolts, bearings, and wind blades. The application of graphite in vacuum furnace greatly simplifies the design and manufacture of vacuum furnace, reduces the consumption of tungsten, molybdenum, tantalum, stainless steel and other metals, reduces the cost, improves the performance of vacuum furnace, and expands the application range of vacuum furnace.

Description

Vacuum furnace graphite parts have been widely used in vacuum furnaces, not only for manufacturing heating elements and heat shields of vacuum furnaces, but also for manufacturing mechanical structures such as brackets, pallets, guides, bolts, bearings, and wind blades. The application of graphite in vacuum furnace greatly simplifies the design and manufacture of vacuum furnace, reduces the consumption of tungsten, molybdenum, tantalum, stainless steel and other metals, reduces the cost, improves the performance of vacuum furnace, and expands the application range of vacuum furnace.

 

Graphite heat field, graphite heater is mainly used for high temperature heating of various industrial kilns, melting furnaces, etc. As graphite materials are widely used, people have higher and higher performance requirements on it, so the graphite heaters we produce are also designed and produced according to the needs of users.

 

1.Graphite resistance temperature coefficient is low, thermal inertia is small, heating and cooling speed is fast, no special requirements in the process of workpiece processing, more suitable for the application of vacuum furnace heater.

2. It is a good heater for vacuum furnace, with the advantages of high temperature resistance, no deformation, impact resistance, large radiation area, good flexibility, easy processing and installation. Electrically, it is easy to make larger heating elements, which can increase voltage and reduce current. Thus saving heat loss.

3. Graphite high temperature strength. At room temperature, the strength of graphite is far less than that of metal, but as the temperature increases, its strength gradually increases and will exceed all oxides and metals.

4. Graphite is easy to obtain and cheaper than metal.

5. Graphite has some properties of metals and ceramics, good electrical and thermal conductivity, porosity and small coefficient of thermal expansion, so graphite has become one of the better thermal shock resistance materials.
