Machine overview
This vacuum quenching furnace is a horizontal single-door industrial equipment. It is heated on all six sides and has multiple layers of stainless steel plates as insulation layers. The furnace body has built-in cooling water channels and inert gas channels.
The wall material of the furnace body is 316L stainless steel with a thickness of 10mm, which has good heat resistance. The heating element is made of graphite or nickel alloy to ensure heating speed and uniformity
This vacuum furnace equipment is composition of a furnace body, a vacuum pump, a built-in water cooling device, a pneumatic control system, an intelligent control system, a heating system, and an electric forklift outside the furnace.
It is suitable for heat treatment such as quenching and annealing of metals in a vacuum environment, and is widely useing in modern industrial manufacturing and heat treatment of rare metals

Advantages of the vacuum quenching furnace
- The interior of the furnace body adopts a multi-layer stainless steel reflection screen, the thickness decreases from 0.5-0 mm, and the design of the folding edge, which not only reduces the loss of thermal efficiency, but also improves the heat insulation, thereby reducing the power consumption.
- Vacuum pumps come from Chinese brands. They have the function of automatic control. If there is an emergency, such as a power outage, the vacuum valve will automatically close to ensure that the furnace still maintains a high-pressure vacuum state. This is the most advanced vacuum pump system currently available.
- Fully automatic control system, using programmed control methods, no matter how complex the vacuum process is, engineers follow the process steps from the touch screen input, it will automatically form a perfect automatic program, and then operate independently without the involvement of workers.
- This vacuum quenching furnace includes a water-cooled automatic distribution system, an automatic cooling furnace body, a furnace door, a vacuum pump, and other parts that require forced cooling. Each pipe has pressure gauges, thermometers, flow meters, and other parts. Engineers can use touch screens to observe the running status of the water-cooled system.
- Fully intelligent safety system, during the heat treatment process of the vacuum furnace, whether the vacuum pump is overloaded, the cooling water temperature is too high, the furnace door is not locked, there is no cooling water, etc., it will issue an alarm sound, and the touch screen will also display the cause of the failure, allowing engineers to quickly solve the problem.
Heat treatment process of the vacuum furnace
- Place the metal parts that need to be heat treated in the vacuum furnace, then close the furnace door and lock it, which is a very important step
- According to the process requirements of heat treatment, edit the heat treatment process of the vacuum furnace. If the program has been saved before, you can select that program and click Confirm.
- Check whether the cooling water and inert gas of the gas quenching vacuum furnace are sufficient, and whether each sensor is operating normally.
- The vacuum furnace will heat up according to the set steps. When the temperature and vacuum pressure reach the set requirements, keep it for 30-120 minutes in this case. This is determined according to the size of the part. The main purpose is to heat the entire metal part very evenly
- In the case of high temperature, the interior of the vacuum furnace is filled with nitrogen, allowing the internal temperature to be rapidly cooled to 250-300 °C for a certain period of time, allowing the metal parts to be fully cooled to produce a chemical reaction
- The metal after quenching is relatively fragile. In order to avoid defects such as cracking, it needs to be tempering at this time, and the temperature needs to be reheat to 500-600 °C. The properties of the metal are different, and the temperature may be different. Then keep it for 1-2 hours.
- Some metal parts need to be tempering 2-3 times to fully eliminate the stress inside the metal parts, so that they can maintain sufficient toughness. Then turn off the heating, let the temperature naturally cool to below 200 °C, open the furnace door, take out the metal parts, and the whole quenching process is over here
Vacuum pump features
This gas-quenching vacuum furnace has multiple vacuum pumps involved in the work, such as roots pumps, maintenance pumps, diffusion pumps, mechanical pumps, etc., as well as many valves with different functions,
which are distributed in a very scientific manner at the desired location
Each vacuum furnace is equipped with an isolation valve and can be started or stopped independently; even in the case of misoperation by engineers, they will not have any malfunction
During the operation of the diffusion pump and the maintenance pump, the oil temperature will be automatically show. When the oil temperature exceeds the set value, the vacuum furnace will automatically alarm and display the cause of the failure on the touch screen
Usually, our vacuum pumps have capacity reserves, which can ensure the efficiency of vacuuming and will not delay the process due to insufficient vacuum pressure
