Can the experimental rotary tube furnace be ventilated with gas?

The experimental rotary tube furnace can be ventilated with gas. It is usually equipped with atmosphere control function, and the sealing system adopts stainless steel flanges, furnace tubes, and high-temperature resistant silicone rubber seals. Inert gases such as nitrogen, argon, and hydrogen can be introduced to meet the atmosphere requirements under specific experimental conditions.

During the ventilation process of the experimental rotary tube furnace, attention should be paid to the type, flow rate, and pressure control of the gas. For example, when introducing inert gas as the working gas, it is necessary to first connect the working gas path, connect the gas outlet end of the furnace to the mechanical pump, then open the inlet valve, turn on the power supply of the vacuum pump, open the outlet valve, and evacuate the furnace tube and gas pipeline. When the vacuum reaches a certain value, close the outlet valve and inlet valve, then slowly open the outlet pressure reducing valve and furnace inlet valve, and closely monitor the pressure gauge to ensure that the pressure is within a safe range.

In addition, the experimental rotary tube furnace can also create a vacuum environment to meet the special requirements of different materials and processes for the atmosphere. By controlling the gas flow rate and pressure, a stable and uniform atmosphere can be created to prevent material oxidation, decarburization, or promote specific chemical reactions, thereby improving material properties.
