Horizontal vacuum furnace
horizontal vacuum furnace are main uses:
Horizontal vacuum furnace is a heat treatment equipment combined with vacuum technology and electric furnace heating technology. It is applied to metallurgy, machinery, aerospace, electronics, light industry and other industries. For example: semiconductor chip sintering and annealing treatment, permanent magnet alloy manufacturing, vacuum brazing, vacuum degassing, metal materials, such as non-oxidizing bright heat treatment process. Because the equipment can provide a clean and impurity-free high vacuum state, the heating temperature is average and can be accurately controlled, so the process premise is superior, can improve the quality of the workpiece and yield.
Technical features of horizontal vacuum furnace:
A number of thermocouples are set up in the working hot zone, and the temperature distribution in the hot zone is displayed and recorded by a function recorder, a temperature controller and a computer.
High-precision, multi-functional inlet temperature controller, can automatically adjust and modify PID parameters, can store 9 temperature control curves, can be modified online.
It can carry out two-way communication monitoring, and display relevant contents in menu, chart, curve, dynamic interface and so on.
The limit vacuum degree is high, the vacuum degree of the furnace body can be better than 5 *10-4Pa in cold state, and it can be maintained in 10-3Pa order in hot state.
The full station dynamic simulation shows that the operation is intuitive and clear.
horizontal vacuum furnace
Vacuum furnace is a vacuum system (made of vacuum pump, vacuum measuring device, vacuum valve and other components, etc.) in the chamber of this particular space to discharge some of the material inside the chamber, so that the pressure in the chamber is less than a standard atmospheric pressure, the chamber space to achieve a vacuum state, this is the vacuum furnace. It is usually connected to a high vacuum pump system in a metal or quartz glass sealed furnace. The furnace vacuum can reach 133 x (10-2-10-4) Pa. The heating system in the furnace can be directly heated by electric resistance wire (such as tungsten wire) by ohmic heating or high frequency induction heating. The maximum temperature can reach 3000 degrees Celsius. Mainly used in ceramic firing, vacuum smelting, electrical vacuum parts degassing, annealing, brazing metal parts, as well as ceramic-metal sealing. The existing vacuum furnace workpiece is inconvenient to join, often need more people to cooperate to complete, waste of human resources, cooling speed is slow, labor efficiency is low.
