1. The equipment consists of heating system, furnace body lifting system, furnace tube rotation system, vacuum system and gas inlet and outlet system.

2. The furnace body lifting system is mainly used for material loading and the furnace body can tilt a large Angle after the material is fired to facilitate the material pouring out; The furnace body is provided with a dip sensor, we can set any allowed range of Angle according to the need, and then the push rod will push the furnace body automatically to reach the Angle we set, more convenient and quick to use;

3. The furnace tube rotation system is the concrete way to realize the rotation of the furnace tube driven by the stepper motor synchronous belt drive. By default, as long as the heating starts, the furnace tube rotation will automatically open, so as to better protect the furnace tube.

4. The vacuum system is connected to the furnace tube by a mechanical pump through the vacuum bellows and flapper valves. The vacuum pressure gauge can visually display the changes in the pressure inside the furnace tube;

5. The inlet and outlet gas system is controlled by two mass flowmeters, and enters the furnace tube after mixing through the gas mixing tank;

6. High precision pressure sensor monitors the pressure in the tube to ensure the stability of the whole system and the safety of the experiment.
