Product Description

1800C vacuum unidirectional hot pressing furnace (20t) used for high temperature sintering of ceramic material silicon carbide


Introduction of 1800 ºC vacuum unidirectional hot pressing furnace (20t):
The vacuum hot pressing sintering furnace is a combination of vacuum / atmosphere, hot pressing and high temperature sintering, which is suitable for the high temperature hot forming of new materials such as powder metallurgy and functional ceramics, such as the true air sintering of transparent ceramics, industrial ceramics and other metals as well as alloy materials composed of refractory metals, and the high temperature sintering of silicon carbide and silicon nitride.
It can also be used for the heat treatment of powder or compact at a temperature lower than the melting point of main components, with the purpose of improving its strength by metallurgical bonding between particles.

Functions and features of 1800 ºC vacuum unidirectional hot pressing furnace (20t):
The structure design of the equipment is advanced and reasonable, the furnace body is made of all stainless steel, the surface is brushed, beautiful and generous;
The electrical components are of famous brands at home and abroad, fully automatic program control. The control system software is developed by our company. The human-machine interface operation system is friendly, simple to operate, fast to respond, and can monitor the working conditions in the furnace in real time. The system is stable and reliable

Main structure of 1800 ºC vacuum unidirectional hot pressing furnace (20t):
Vacuum hot pressing furnace is mainly composed of furnace body, furnace door, heating and heat preservation and temperature measurement system, vacuum system, air charging system, water cooling system, control system, hydraulic system, etc.
1. Furnace body: double-layer 304 stainless steel water-cooled structure, precision polishing, which is conducive to shortening the air extraction time and easy to clean;
2. Furnace cover: double-layer water-cooled structure, with 304 inner and outer walls and precision polishing treatment, and cooling water in the middle.
3. Heating, heat preservation and temperature measurement system: the heating system adopts graphite tube heater, which ensures the best temperature uniformity and uniform heating of workpiece, and is convenient for the maintenance and replacement of heating body. The side and bottom thermal insulation screens are made of composite thermal insulation layer composed of hard felt and soft felt, which are processed into a whole thermal insulation system. The temperature is controlled by thyristor, equipped with PID function instrument, digital display meter, with overtemperature sound light alarm function, PLC touch screen can also be used for automatic control, and historical data can be retained for easy analysis of sintering process.
4. Vacuum system: it is composed of oil diffusion pump, roots pump, mechanical pump distribution magnetic differential pressure valve (to prevent sudden power failure and mechanical pump oil backflow), air release valve, vacuum butterfly valve, vacuum pressure gauge (± PA) bellows, vacuum pipeline and bracket, etc.
5. Inflation system: it is composed of various pipes and valves, and equipped with electromagnetic vent valve and pressure sensor. When the pressure in the furnace is higher than the safety value, it will automatically deflate. The inflation pipe is equipped with needle valve, which can control the inflation amount, and is used for the atmosphere requirements of argon and nitrogen charging required by sintering process;
6. Water cooling system: it is composed of various valve and pipeline related devices and is equipped with water cut-off sound and light alarm to automatically cut off the heating source or function.
7. Gas filling device: mainly composed of gas filling valve, flowmeter, gas filling pipeline, etc., which is used for the atmosphere requirements of argon and nitrogen filling required by smelting process;
8. Control system: it is composed of PLC, temperature controller, vacuum gauge, voltage ammeter, DC regulated power supply, air switch, contactor, relay, button, indicator light, etc. to realize power supply, control, record, monitoring, alarm protection functions.
9. Hydraulic system: adopt electric input mode. The hydraulic station is equipped with imported proportional valve, pressure sensor, displacement display, grating ruler (ranging accuracy 0.02mm), hydraulic cylinder and other related hydraulic devices. The pressure regulation is semi-automatic and can be manually adjusted. The instrument can be set to automatically adjust the pressure, and can realize stable and pressure maintaining.
