The advantages of vacuum oven mainly include the following 5 points:
1) The oxidation and decarburization of the workpiece surface during heating are completely eliminated, and a clean surface can be obtained without deteriorating the layer. For those tools that only grind one side during the grinding process (such as twist drills that expose the decarburized layer on the flute surface directly on the cutting edge), this can have a large impact on cutting performance.
2) No pollution to the environment, no need to deal with the three wastes.
3) The temperature measurement and monitoring accuracy of the ambient oven is significantly improved. The indicated value of the thermocouple and the furnace temperature are up to ±1.5°C. However, the temperature difference between a large number of workpieces in the furnace is relatively large. If forced circulation of rare gas is used, the temperature difference can still be controlled within ±5°C.
4) A high degree of mechatronics. On the basis of improving temperature measurement and control accuracy, workpiece movement, air pressure adjustment, power adjustment, etc. can be programmed in advance, and quenching and tempering can be carried out step by step.
5) The energy consumption is significantly lower than that of the salt bath furnace. The modern excellent industrial vacuum oven heating chamber adopts the heat insulation wall and barrier made of good heat insulation material, which can highly concentrate the electric heating energy in the heating chamber, and the energy saving effect is remarkable.
In addition, the advantage of the vacuum oven is that it is quite safe to use, has no pollution to the environment, and does not emit any waste gas or waste water during use, so it has a good protective effect on the atmospheric environment. It can not only process and produce at a fast speed, but also improve the work efficiency, and then ensure the treatment of environmental pollution, without the need for three waste treatment, and solve the pressure of air pollution.
The degree of mechatronics of the vacuum oven is also one of the advantages of the vacuum oven. The temperature control is quite precise, so on the basis of the improved accuracy, the movement of the workpiece and the adjustment of the air pressure can be programmed in advance. When writing the program later, you can enter the implementation work step by step. After the program is realized, all working systems can work as required, which largely avoids the waste of human resources. At the same time, the vacuum oven environment detection equipment has high working efficiency, which can greatly save working resources and avoid excessive consumption and waste of energy. The high concentration of electric heating energy can make the heating efficiency higher, and the energy saving effect can be said to be quite significant. In terms of energy saving and environmental protection, it absolutely meets high standards.
