Vacuum Hot Press Furnace

A brief description:

The vacuum hot pressing furnace produced by our company adopts imported graphene materials, advanced technology, high quality, and perfect after-sales service. It is highly praised and praised by users. It can be designed according to user requirements and provide perfect after-sales service.

The main purpose of vacuum hot pressing furnace equipment:

Vacuum hot pressing sintering furnace is a combination of vacuum/atmosphere, hot pressing forming and high temperature sintering. It is suitable for high temperature hot forming of new materials such as powder metallurgy and functional ceramics. Vacuum sintering of alloy materials composed of metals and high-temperature sintering of ceramic materials silicon carbide and silicon nitride can also be used for heat treatment of powder or compact at a temperature lower than the melting point of the main component, the purpose is to achieve metallurgical bonding between particles increase its strength.

Vacuum hot pressing furnace is mainly composed of furnace body, furnace door, heating and heat preservation and temperature measurement system, vacuum system, inflation system, water cooling system, control system, hydraulic system and so on.

1. Furnace body:

Double-layer 304 stainless steel water-cooled structure, precision polishing, which is conducive to shortening the pumping time and is easy to clean;

2. Furnace cover: double-layer water-cooled structure, the inner and outer walls are 304 and have been precision polished, and cooling water is passed through the middle.

3. Heating, heat preservation and temperature measuring system: The heating system adopts graphite cylindrical heater, which ensures the best temperature uniformity and uniform heating of the workpiece, and is convenient for maintenance and replacement of the heating element. The heat insulation screens on the side and bottom are made of a composite insulation layer composed of hard felt and soft felt, which is processed into an integral heat insulation system. It adopts thyristor temperature control, equipped with PID function instrument, digital display meter, has over-temperature sound and light alarm function, and can also choose PLC touch screen automatic control, and keep the history

Historical data is convenient for analyzing the sintering process.

4. Vacuum system: oil diffusion pump, Roots pump, mechanical pump with electromagnetic differential pressure valve (to prevent sudden power failure, mechanical pump oil backfill), inflation valve, air release valve, vacuum butterfly valve, vacuum pressure gauge (±Pa) ripple Tubes, vacuum lines and brackets.

5. Inflating system: It is composed of various pipelines and valves, and is equipped with an electromagnetic deflation valve and a pressure sensor. When the pressure in the furnace is higher than the safe value, it will automatically deflate. There is a needle valve on the inflation pipeline to control the amount of inflation. , for the atmosphere requirements of argon and nitrogen required for the sintering process;

6. Water-cooling system: It is composed of various valves and pipe-related devices and is equipped with sound and light alarm for water cut-off to automatically cut off the heating source or function.

7. Inflatable device: mainly composed of inflatable valve, flow meter, inflatable pipeline, etc., used for the atmosphere requirements of argon and nitrogen in the smelting process;

8. Control system: It is composed of programmable logic controller PLC, temperature controller, vacuum gauge, voltage ammeter, DC stabilized power supply, air switch, contactor, relay, button, indicator light, etc., to realize power supply, control, recording, Monitoring, alarm protection function.

9. Hydraulic system: Electric input mode is adopted. The hydraulic station is equipped with imported proportional valves, pressure sensors, displacement monitors using grating rulers (ranging accuracy 0.02mm), hydraulic cylinders and other related hydraulic devices. The pressure adjustment is semi-automatic and can be adjusted manually. The instrument can be set to automatically adjust the pressure, and can realize pressure stabilization and pressure maintenance.
