The advantages of vacuum furnace

The advantages of vacuum furnace

1, completely eliminates the oxidation and decarburization on the surface of the workpiece during the process of heating, clean surface without metamorphic layer can be obtained. That only when grinding mill side of cutting tools (such as after twist drill grinding groove on the surface of the decarburization layer directly exposed to improve the performance of blade, cutting relationship greatly.
2, on the environment pollution-free, "three wastes" treatment is not required.
3, obviously improve the temperature measurement, the monitoring precision. Indicated value of thermocouple temperature and furnace temperature reached plus or minus 1.5 ° c. But in different parts of a large number of artifacts in the furnace temperature difference is bigger, if USES the rarefied gas forced circulation, can still be controlled within + / - 5 ° c temperature difference.
4, high degree of mechanical and electrical integration. Increase in the temperature measurement and control accuracy, on the basis of the workpiece moving, pressure adjustment, power adjustment, etc all can set programming in advance, according to the steps to implement the quenching and tempering.
5, significantly below the salt bath furnace energy consumption. Modern advanced vacuum furnace heating chamber is made of high quality insulation material of insulation walls and barriers, electric energy can be highly focused on indoor heating, energy saving effect is remarkable.
