During operation, tube furnaces typically require the introduction of different types of gases to meet specific heat treatment processes and requirements. Let's take a detailed look at which gases can be supplied to a supervised furnace!

Oxygen: The main function of oxygen in a tube furnace is to provide oxygen supply agent, promote combustion process, accelerate heating speed, and improve process efficiency. Meanwhile, it can also promote redox reactions, which is beneficial for improving the heat treatment effect.
Nitrogen: Nitrogen is an inert gas commonly used to protect the surface of heat-treated parts from oxidation. In addition, nitrogen can also be used in conjunction with other ventilation gases to improve the heat treatment effect.
Air: In some processes, tube furnaces can use air as the ventilation gas. Air can act as an oxidizing agent under appropriate conditions, thereby improving the effectiveness of heat treatment.
Hydrogen: Hydrogen, as another important gas for ventilation, plays a major role in accelerating the heating process and improving the effectiveness of heat treatment in tubular furnaces.
Inert gases, such as argon, are commonly used to provide inert gas environmental protection to prevent oxidation or contamination of heat-treated components at high temperatures.
In addition, according to specific heat treatment processes and experimental requirements, other types of gases such as ammonia and hydrocarbons can also be introduced. The selection of the types and proportions of these gases depends on specific process requirements to achieve better heat treatment results.

It should be noted that when using a tube furnace for heat treatment, operating procedures and safety regulations should be strictly followed. During the ventilation process, close attention should be paid to the flow rate and pressure of the gas to ensure that it can be evenly and stably introduced into the furnace. Meanwhile, during the process of heating, insulation, and cooling, it is necessary to closely monitor the changes in temperature and pressure inside the furnace to prevent any abnormal situations.Click to learn more tube furnaces!
