High Quality Industrial Vacuum Furnace Graphite electrode vacuum furnace China wholesale​

Product description

Graphite electrode vacuum furnace that is in the furnace cavity this specific space using vacuum system (by vacuum pump, vacuum measuring device, vacuum valve and other components after careful assembly) will be part of the material in the furnace cavity discharge, so that the pressure in the furnace cavity is less than a standard atmospheric pressure, the space in the furnace cavity so as to achieve a vacuum state, which is the vacuum furnace.

Graphite electrode vacuum furnace vacuum environment for heating equipment. The furnace chamber is sealed in a metal or quartz glass enclosure and is connected to a high vacuum pump system by piping. The vacuum of the furnace chamber can reach 133×(10~10)Pa. The heating system in the furnace can be directly heated by electric resistance wire (such as tungsten wire) or by high frequency induction heating. The highest temperature can reach about 3000℃. It is mainly used for ceramic firing, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing, etc.

Graphite electrode vacuum furnace advantages

1. Oxidation and decarburization of the workpiece surface during the heating process are completely eliminated, and a clean surface without deterioration layer can be obtained. This is more relevant to the improvement of cutting performance of those tools that are only ground on one side during sharpening (such as twist drill grinding so that the decarburized layer on the groove surface is directly exposed to the edge).

2.No pollution to the environment, no need for three waste treatment.

3. The accuracy of furnace temperature measurement and monitoring is significantly improved. The indication value of the thermocouple and furnace temperature to ± 1.5 ° c. But a large number of different parts of the furnace workpiece temperature difference, if the use of thin gas forced circulation, can still be controlled within the ± 5 ° c temperature difference.

4. High degree of electromechanical integration. On the basis of improved precision in temperature measurement and control, workpiece movement, air pressure adjustment, power adjustment, etc. can be pre-programmed to set the steps to implement quenching and tempering.

5.Energy consumption is significantly lower than that of salt bath furnace. Modern advanced vacuum furnace heating chamber using excellent insulation materials made of heat insulation wall and barrier, can be highly concentrated in the heating chamber of electric energy, energy-saving effect is significant.
