Vacuum heat treatment furnace

Vacuum heat treatment furnace is a fast developing heat treatment technology in recent years. It has many advantages, such as good quality, good energy saving effect and no pollution. It has been widely used in industrial production process.

Vacuum heat treatment technology is the combination of vacuum technology and heat treatment technology, which can effectively improve the quality of metal materials and promote the continuous improvement of industrial production technology in China. When metal is heated in an air furnace, it reacts with oxides such as oxygen, water vapor and carbon dioxide in the air. The substances generated will seriously affect the quality of metal materials, resulting in the reduction of the quality of metal materials. Vacuum heat treatment furnace can solve this problem very well. In the process of metal heating, the metal is in a completely vacuum environment, and the heat treatment process is completed under different external environment contacts, thus effectively avoiding impurities and improving the quality of metal materials.

Vacuum Heat Treatment Furnace Characteristics
Unique Water Cooling Device Settings
Because the vacuum heat treatment furnace needs to carry out effective heat treatment of metal materials in vacuum state, the vacuum heat treatment furnace needs to effectively cool all parts of the furnace in the use process to ensure the safety of the equipment and the normal operation of the equipment. At present, most vacuum heat treatment furnaces in our country use water-cooled devices to reduce the temperature of their parts, so that the vacuum sealing ring of vacuum heat treatment furnaces will not be overheated or burned, ensuring the normal operation of vacuum heat treatment furnaces, and improving the service life of vacuum heat treatment furnaces.

Good Sealability
Good sealing is the main feature of vacuum heat treatment furnace, and only by ensuring the sealing of the furnace, can the contact between metal materials and external oxides be reduced, thus effectively improving the quality of metal materials. In the design process, in order to ensure the vacuum performance of vacuum heat treatment furnace, vacuum heat treatment furnace often undergoes strict processing procedures, such as gas-tight welding of furnace body, try not to open holes on vacuum heat treatment furnace body, so as to reduce the chance of air mixing. At the same time, other parts of the vacuum heat treatment furnace body should be strictly sealed to improve the overall sealing of the vacuum heat treatment furnace.

High Efficiency Thermal Insulation Materials and Heating Materials
Because the internal operating environment of vacuum heat treatment furnace will not be mixed with oxygen and other oxidizing gases, it can effectively improve the heating efficiency and overall quality of metal materials. It is also based on this problem that vacuum heat treatment furnace can choose heating and insulation materials without fear of oxidation, and more attention can be paid to materials. The heating efficiency and insulation efficiency of the material. Generally speaking, the insulating materials and heating materials used in vacuum heat treatment furnace are tantalum, tungsten, molybdenum and graphite. Although these materials are easy to oxidize in atmosphere, because of the characteristics of vacuum heat treatment furnace, these insulating materials and heating materials can play a good role in the actual production process.

Automated Operation
During the operation of the vacuum heat treatment furnace, dozens of actions are needed to complete the heat treatment of metal materials. Under the manual operation, it is easy to make operational errors, resulting in confusion in the production process and the decline in the quality of metal materials. Thus, it is necessary to ensure the continuity and existence of the vacuum heat treatment furnace. As a result, another feature of vacuum heat treatment furnace is its efficient automatic production mode. The degree of automation of vacuum heat treatment furnace is very high. Through the operation of relevant programs, all the actions in the process of vacuum heating furnace can be guaranteed to be completed in less than 15 seconds without any omissions. Thus, the overall operation efficiency of vacuum heating furnace can be effectively guaranteed and the quality of heating material can be guaranteed.

Unique Low Voltage and High Current Design
Generally speaking, there is no gas in the environment of the vacuum heat treatment furnace. If the voltage inside the container is too high, it is very easy for the electrified conductor to cause damage to the relevant electrothermal components during the discharge process, thus making the equipment unusable. In order to solve this problem, vacuum heat treatment furnaces are designed with low voltage and high current to avoid the equipment impact caused by the discharge process. At the same time, the structure of electrothermal components will take some preventive measures to avoid glow discharge or arc discharge.
