Vacuum 1600 ℃ hot bench，This electric furnace is a desktop high temperature vacuum heating table. It is used for sintering treatment of small samples of functional ceramics, optical materials, carbon composite materials, cemented carbide, powder metallurgy, etc. under high temperature conditions, and can also be used for electrical signal testing of samples in high temperature vacuum environment.

　　一： Structure description

1. Vacuum chamber: The main material is 304 stainless steel, and the external forced air pressure is used to dissipate heat.

2. Vacuum interface: vacuum interface KF25. air inlet 6mm quick screw, air outlet 8mm pagoda

3. Heating and heat insulation: heating element, tungsten sheet heating, external alumina insulation material, molybdenum foil and stainless steel heat shield

4. Furnace door: stainless steel double layer water cooling.

5. temperature control box: ordinary carbon steel surface spray treatment.

6.The insulated cover can reduce the heat to the minimum at any time and the heating time is the shortest. The gap between the sealing cover and the hot plate is kept at 26mm to ensure high temperature accuracy and high-intensity heating of smooth parts. The whole shell is made of stainless steel.

7.The temperature controller is connected by two plug-in cables.

8.The programmable controller can carry out the control of a specific program, including the heating stage, the holding stage and the cooling stage.

9.The input adopts a digital calibration system with accurate and stable measurement, supports a variety of thermocouple and thermal resistance specifications, and the highest resolution is 0.01 ℃.

10.Adopt advanced AI artificial intelligence PID adjustment algorithm, no overshoot, with auto-tuning (AT) function.

11.It adopts advanced modular structure and provides abundant output specifications, which can widely meet the needs of various applications, with fast delivery and easy maintenance.

12.Up to 30 sections of programs can be set up and can run in cycles. The user-friendly design of the operation method is easy to learn and use.

Allows self-editing operation authority and interface to form “customized” own instrument.

13.Universal 100-240VAC input range switching power supply or 24VDC power supply, and has a variety of panels and appearance sizes for selection.
