The machine include:

The vacuum furnace is of horizontal and single chamber structure, with double-layer water cooling and front door structure.

It consists of furnace body, heating chamber, vacuum system, water cooling system, electric control and power supply system.

1. Furnace body: The overall structure of the furnace is composed of furnace shell, furnace door and lock mechanism. The furnace shell and furnace door are double jacket cold wall structure. The furnace body is composed of furnace barrel and furnace door, which are made of carbon steel. The furnace door is a front door structure, which is welded by double elliptical head and circular flange, and the flange is equipped with O-ring. The workpiece can be loaded and taken out by opening the front furnace door, and the main body of the heating chamber, the electrode and the air extraction port of the main vacuum pump are set in the middle.

2. Heating Chamber: The heating system adopts silicon carbide rod and high purity alumina polycrystalline fiber as insulation furnace, which can avoid short circuit to the greatest extent; The insulation between the circuit and the furnace body is good, which is convenient for disassembly, cleaning and replacement.

3. Vacuum system: Rotary vane pump + roots pump + diffusion pump unit, high vacuum pneumatic flapper valve, vacuum gauge, vacuum pressure gauge, vacuum vent valve, vacuum pipeline, etc., with air filling interface. In order to reduce the vibration of the furnace, the high vacuum corrugated pipe is used to connect the vacuum pipe with the pump, and the vacuum is measured by the digital display composite vacuum gauge. Limit vacuum: 6.7 * 10-4Pa (empty furnace, cold state)

4. Electrical Power control system

A. It is composed of programmable touch screen temperature control meter, voltmeter and ammeter, indicator light, knob, button, etc. to realize the functions of power supply, control, alarm and protection.

B. The programmable controller can control the temperature accurately. The whole process can be carried out automatically with manual operation system.

C. K type Thermocouple

D. Ruibao digital display vacuum gauge is used for vacuum measurement, which is integrated into the control panel. It has the safety protection functions of over temperature, water cut-off and power-off. The furnace body is equipped with a safety valve device.

E. The heating power supply adopts single-phase thyristor power supply with low voltage and high current

5. Water Cooling system: Cooling water is needed for vacuum furnace body, furnace door and vacuum unit. The system is distributed from the main water supply pipe to each cooling part, adopts closed water circulation system, and is equipped with automatic water chiller system. The inlet and return water pipes are all stainless pipes.

6. Safety: The safety system includes water cut-off, over temperature and heating over-current
