High temperature vacuum tube furnace

High temperature vacuum tube furnace technical characteristics

1. This equipment introduces foreign advanced technology and independently develops and produces a new type of high-efficiency energy-saving and environmental protection electric furnace. The equipment has unique design technology, beautiful appearance, advanced and reasonable structure, simple and convenient operation, and adopts high-quality cold-rolled steel plate and precision CNC machine tool. Processing, luxury, exquisite imported epoxy powder two-color electrostatic spraying process, after processing, high temperature resistance, corrosion resistance, long-term color fastness.

2. The furnace has the advantage of uniform temperature field. The surface temperature of the double-layer heat-resistant furnace body is close to room temperature, and the temperature rise, maintenance and cooling rate can be adjusted arbitrarily. The furnace is all made of imported ultra-high temperature composite fiber materials, adopting unique numerical control technology, with heat resistance. Strong impact resistance, heat resistance, good corrosion resistance, no collapse, no crystallization, no slag, no pollution, long service life.

3. The control system adopts microcomputer intelligent regulation technology, with PID regulation, automatic control, self stabilization function, 50 section program, and can prepare various heating, constant temperature and cooling programs, with high temperature control accuracy, energy saving and high stability.

4. The protection device adopts independent protection: overheating, overvoltage, overcurrent, balance of payments, power failure, leakage, short circuit, etc.

5. It can be vacuumized and has a variety of gases. The valve is equipped with intake valve, exhaust valve and vacuum valve. Pressure reducing valve and safety valve can be filled with high-pressure gas through various gases, such as argon, nitrogen, oxygen, carbon monoxide, ammonia decomposition gas, etc. the vacuum system adopts multi-stage O-type seal, and both ends of the heat furnace tube are equipped with wear-resistant rubber pads to ensure reliable sealing, small vacuum leakage, the instrument displays the pressure in the furnace, vacuum interface conditions, fast flange connection and square Operation of the toilet.

High temperature vacuum tube furnace additional configuration

1. In addition, through the control software independently developed by our company, the electric furnace is connected with the computer, which can realize the remote control of single or multiple electric furnaces, start the electric furnace, cut off the power, set the temperature control program, store the temperature control program, view the historical curve, print the historical curve, etc

2. The mass flowmeter can accurately display the gas flow, and can be programmed to automatically control the gas flow;

3. Molecular pump, diffusion pump, roots pump and mechanical pump can meet various vacuum requirements;

4. Digital vacuum meter can display vacuum with high precision.
