Vacuum Industrial Furnace Advantages

1. The oxidation and decarbonization of the workpiece surface during heating can be eliminated completely, and the clean surface without deterioration can be obtained. This is of great importance to the improvement of the cutting performance of tools that only grind one side when grinding, such as twist drill grinding, which directly exposes the decarburized layer on the groove surface to the edge.

2. It does not pollute the environment and does not need to dispose of the three wastes.

3. The accuracy of furnace temperature measurement and monitoring has been greatly improved. The indication value of thermocouple and furnace temperature reach (+1.5) C. However, the temperature difference in different parts of a large number of workpieces in the furnace is large. If the forced circulation of rarefied gas is adopted, the temperature difference can still be controlled within the range of (+5) C.

4. High degree of mechatronics. On the basis of improving the accuracy of temperature measurement and control, workpiece movement, air pressure regulation and power regulation can be programmed in advance, and quenching and tempering can be carried out step by step.

5. Energy consumption is significantly lower than that of salt bath furnace. The heating chamber of modern advanced vacuum industrial furnace adopts insulation wall and barrier made of high quality thermal insulation material, which can highly concentrate the electric heat energy in the heating chamber, and the energy saving effect is remarkable.
