High temperature graphite vacuum furnace detailed introduction:
Advantages of high temperature graphite vacuum furnace
1) Completely eliminates oxidation and decarburization of the workpiece surface during heating, and obtains a clean surface without a metamorphic layer. This has a great impact on the improvement of cutting performance of tools that only grind one side during sharpening (such as twist drills that expose the decarburization layer on the groove surface directly to the cutting edge after grinding).
2) No pollution to the environment, no need for three wastes treatment.
3) The accuracy of furnace temperature measurement and monitoring is significantly improved. The indicated value of the thermocouple is ±1.5°C with the furnace temperature. However, the temperature difference between different parts of a large number of workpieces in the furnace is large. If rarefied gas forced circulation is used, it can still be controlled within the temperature difference range of ±5°C.
Structure of high temperature graphite vacuum furnace
Generally composed of main machine, furnace, electric heating device, sealed furnace shell, vacuum system, power supply system, temperature control system and furnace transport vehicle. The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surface of the detachable parts is sealed with vacuum sealing material. In order to prevent the furnace shell from deforming after heating and the sealing material from deteriorating after heating, the furnace shell is generally cooled by water or air. The furnace is located in the sealed furnace shell. According to the purpose of the furnace, different types of heating elements are installed inside the furnace, such as resistors, induction coils, electrodes and electron guns. The vacuum furnace for melting metal is equipped with a crucible in the furnace, and some are also equipped with automatic pouring devices and manipulators for loading and unloading materials. The vacuum system is mainly composed of vacuum pumps, vacuum valves and vacuum gauges.
Application of high-temperature graphite vacuum furnace
It appeared around the 1930s. In 1927, the United States made a vacuum annealing furnace for electrical materials, and in 1953, the vacuum consumable arc furnace was used in industry.
