What are the advantages of a vacuum furnace?
High degree of integration of mechanical and electrical. On the basis of the improvement of temperature measurement and control accuracy, the workpiece movement, air pressure regulation, power adjustment can be programmed in advance, and quenching and tempering are carried out according to the steps.
Energy consumption is lower than salt bath furnace. Modern advanced vacuum industrial furnace heating chamber is made of high quality heat insulation material and wall, which can concentrate electric heating energy into heating chamber with remarkable energy saving effect.
The accuracy of furnace temperature measurement and monitoring is obviously improved. The indicating temperature of the thermocouple and the temperature of the furnace reach 1.5 C. But there is a large temperature difference in a large number of workpieces in different parts of the furnace. If the forced circulation of the rarefied gas is adopted, the temperature range of the temperature range of + 5 DEG C can still be controlled.
No pollution to the environment, no need for three wastes treatment.
The utility model can completely eliminate the oxidation and decarburization of the workpiece surface in the heating process, and can obtain clean surfaces without deterioration layers. For cutting tools that grind only one side of grinding (such as twist grinding, the surface of the groove surface is exposed to the blade directly), the cutting performance is greatly improved.
