The SY2 series vacuum furnace is a kind of equipment for heating in a vacuum environment. It is connected with a high vacuum pump system by a pipe in a furnace chamber sealed by a metal cover or a quartz glass cover. The vacuum degree of furnace chamber can reach 133×(10-2~10-6)Pa. The heating system in the furnace can be directly heated by resistance furnace wires (such as tungsten wires), or can be heated by high-frequency induction heating. The highest temperature can reach around 3000ºC. Mainly used for ceramic firing, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing, etc.
Product Structure
The vacuum furnace is generally composed of a host, a furnace chamber, an electric heating device, a sealed furnace shell, a vacuum system, a power supply system, a temperature control system, and a transport vehicle outside the furnace.
The sealed furnace shell is welded with carbon steel or stainless steel, and the joint surface of the detachable part is sealed with a vacuum sealing material. In order to prevent the furnace shell from being deformed after heating and the sealing material is heated and deteriorated, the furnace shell is generally cooled by water cooling or air cooling. The furnace chamber is located in the sealed furnace shell. According to the purpose of the furnace, different types of heating elements are installed inside the furnace chamber, such as resistors, induction coils, electrodes, and electron guns. There are crucibles in the chamber of the vacuum furnace for smelting metals, and some are equipped with automatic pouring devices and manipulators for loading and unloading materials. The vacuum system is mainly composed of vacuum pump, vacuum valve and vacuum gauge.

NOTE:Vacuum furnaces are non-standard customized products, and the product structure can be designed according to customer requirements.
Product Advantages
1. The oxidation and decarburization of the surface of the workpiece during the heating process are completely eliminated, and a clean surface without deterioration layer can be obtained.
2. No pollution to the environment, and no need to deal with the three wastes.
3. The accuracy of furnace temperature measurement and monitoring is obviously improved. The indicating value of the thermocouple and the temperature of furnace reach ±1.5ºC. However, the temperature difference between a large number of workpieces in the furnace is relatively large, if the forced circulation of rare gas is adopted, the temperature difference can still be controlled within the range of ±5ºC.
4. High degree of mechatronics. On the basis of improving the accuracy of temperature measurement and control, workpiece movement, air pressure adjustment, power adjustment, etc. can be pre-programmed and set, and quenching and tempering can be implemented step by step.
5. Significant energy saving. Modern advanced vacuum furnace heating chamber adopts thermal insulation walls and barriers made of high-quality thermal insulation materials, which can highly concentrate the electric heating energy in the heating chamber, and the energy-saving effect is significant.
6. The heat preservation material in the furnace adopts alumina ceramic fiber, which has good heat preservation and energy saving effect. The outer closed vacuum tank is equipped with a double-layer water cooling system. The whole machine has a novel structure and is easy to operate.
7. The size, vacuum degree and operating temperature of furnace chamber can be customized according to customer needs. The highest vacuum degree can reach 10-6Pa.
