vacuum furnace advantages

Vacuum furnace, that is to say, the vacuum system (assembled by vacuum pump, vacuum measuring device, vacuum valve and other elements) is used in the specific space of the furnace cavity to discharge some substances in the furnace cavity, so that the pressure in the furnace cavity is less than a standard atmospheric pressure, and the space in the furnace cavity can realize the vacuum state. This is the vacuum furnace. Let’s talk about the advantages of SIMUWU vacuum furnace.

1. There is no pollution to the environment and there is no need for three wastes treatment.

2. Completely eliminate the oxidation and decarburization of the workpiece surface in the heating process, and a clean surface without deterioration layer can be obtained. This is of great importance to the improvement of cutting performance of tools that only grind one side (such as the decarburized layer on the groove surface directly exposed to the cutting edge after grinding by twist drill).

3. 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 pre programmed, and quenching and tempering can be carried out step by step.

4. The accuracy of furnace temperature measurement and monitoring is significantly improved. The indicated value of thermocouple and temperature of furnace reach ± 1.5 ° C. However, the temperature difference in different parts of a large number of workpieces in the furnace is large. If the thin gas is used for forced circulation, the temperature difference can still be controlled within ± 5 ° C.

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

The vacuum furnace is generally composed of the main engine, furnace, electric heating device, sealed furnace shell, vacuum system, power supply system, temperature control system and external transport vehicle. The sealing furnace shell is welded with carbon steel or stainless steel, and the joint surface of detachable parts is sealed with vacuum sealing material. In order to prevent the shell from deforming and the sealing material from deteriorating after heating, the shell is usually cooled by water or air cooling. The above is to introduce the advantages of SIMUWU vacuum furnace, hoping to help you.
