Vertical Vacuum Furnace

Construction of Vertical Vacuum Furnace
Vertical vacuum furnace is generally composed of furnace, electrothermal device, sealed shell, vacuum system, power supply system and temperature control system. Sealing furnace shell is welded with carbon steel or stainless steel, and the joint surface of removable parts is sealed with vacuum sealing material. This equipment is used for annealing, degassing and removing surface oxides of glass-molybdenum alloys and various electro-vacuum devices in vacuum.

Usage Characteristics of Vertical Vacuum Furnace:
(1) The furnace is a vacuum heat treatment equipment for long rod workpieces and heavy workpieces. It is also one of the modern vacuum furnaces in recent years.
(2) Heavy, large and long workpieces can be used for vacuum heat treatment, vacuum brazing, vacuum sintering and other processes.
(3) The treated parts are charged and discharged from bottom to top of the furnace.
(4) Automation and intellectualization of operation processes such as feeding and discharging.

The difference between vertical and horizontal vacuum furnaces:
If we say the difference between vertical vacuum furnace and horizontal vacuum furnace, simply say that the internal layout is different, vertical is "vertical" layout, horizontal is lying. Vertical type usually contains lifting mechanism to take and place the workpiece. Horizontal vacuum furnace takes and places the workpiece by opening side door.

Characteristics of vertical vacuum furnaces:
1. Temperature categories are: 1000 1200 1400 1600 C.
2. Type of water cooling system: circulating water cooling (with energy-saving water source).
3. Temperature control accuracy: +1 C furnace temperature uniformity: +7.5 C.
4. Energy-saving, good stability, fast heating, high accuracy, good insulation.
5. It can draw up multi-stage heating, holding and cooling curves, fully automatic heating, holding and cooling, over-temperature protection and semi-automatic control, and can set up program to stop automatically at the end of operation without sending people on duty.
6. Furnace is all insulated by metal, cooling time is fast, the furnace body is relatively clean, pollution-free and so on.
7. Furnace body temperature is close to room temperature and can pass various gases (oxygen, nitrogen, argon, hydrogen, etc.).
