In the production process of vacuum furnace, graphite components are loved by the manufacturers. Graphite material has won the broad application market with its unique properties. Graphite is often used in vacuum furnace as: thermal insulation carbon felt, heating rod, hearth guide rail, guide nozzle, conductive rod, connector, support column, hearth support, graphite screw, nut and other products.
Heating rod: according to the different working conditions, select the most appropriate graphite material to process graphite heating rod, comprehensively consider the use effect, service life, production cost and other factors, so as to achieve the best cost performance of graphite heating rod. The graphite heating rod can also be selectively treated with anti-oxidation to improve the use effect and prolong the service life.
The advantages of graphite furnace bed guide: maintenance free, low maintenance, no need to lubricate the pipeline system and equipment; Long service life, long-term automatic maintenance of rail surface lubrication film protection; Greatly reduce the cost of lubricating oil; Easy to maintain machine cleaning, no waste oil leakage, environmental pollution; High quality, preferential price.
Advantages of graphite element:
The results are as follows: 1. The strength of graphite at high temperature is better than that of metal at room temperature, but with the increase of temperature, the strength of graphite will gradually increase, which will exceed that of all oxides and metals;
2. Graphite is easy to make and cheaper than metal
3、Graphite has some properties of metal and ceramic. It has good conductivity, thermal conductivity, porosity and small coefficient of thermal expansion. Therefore, graphite has become one of the most heat-resistant materials
4、Graphite has small temperature coefficient of resistance and low thermal inertia, and can be heated and cooled rapidly. There is no special requirement in the process of workpiece treatment, so it is more suitable for the application of vacuum furnace heater.
5、It has 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 the voltage and reduce the current. Thus, the heat loss is saved.
