In manufacturing industries, the use of furnaces is indispensable for generating high levels of heat to facilitate various physical processes. To ensure the success of heat treatment procedures, it is crucial to maintain a controlled atmosphere within the furnace that contains neutral gases, devoid of any interference with the nature and outcome of these processes. Hydrogen, an essential gas, is the preferred choice for creating the desired atmosphere inside the furnace. Gaztron Engineering Pvt. Ltd offers an onsite hydrogen generator capable of providing a continuous supply of hydrogen for heat treatment furnaces.

Hydrogen Atmosphere in Heat Treatment Processes:

Industrial furnaces generate an immense amount of heat through fuel combustion within a controlled atmosphere. This heat is utilized for a range of heat treatment processes, where the presence of hydrogen is essential to prevent spontaneous reactions with oxygen in the air. The primary purpose of introducing hydrogen into a heat treatment furnace is to prevent the oxidation of iron or steel.

Here are some heat treatment processes that require a hydrogen atmosphere:

1. Bright annealing: Metals are subjected to high temperatures within a controlled hydrogen atmosphere and gradually cooled to enhance their softness. This heat treatment process can alter both the physical and chemical properties of metals.

2. Steel annealing: Steel is heated to around 700°C to eliminate impurities from the metal. This process is widely employed in industries that require modification of the ductility and hardness of steel for manufacturing purposes.

3. Sintering: In sintering, multiple solid particles are subjected to high temperature and pressure, resulting in the formation of a solid lump. This heat treatment process is commonly used to create metal objects with unique shapes.

4. Brazing: Brazing involves joining two metal or ceramic objects by pouring a compatible metal, in its molten state, over the joint. The filler metal is heated to approximately 450°C, melting and spreading through capillary action to fill the joint gap.

5. Vacuum procedures: Hydrogen can serve as the residual gas in a vacuum system, as it is less prone to absorption or diffusion into metals compared to oxygen or other gases.

The hydrogen generator supplied by Gaztron Engineering can produce hydrogen with purity levels of up to 99%, ensuring the integrity of heat treatment processes and preventing interference from other gases. The continuous supply of hydrogen for heat treatment furnaces contributes to the popularity of Gaztron Engineering's hydrogen plant.

By utilizing the hydrogen generator from Gaztron Engineering, manufacturing industries can maintain a controlled atmosphere rich in hydrogen, enabling efficient and successful heat treatment procedures without the risk of oxidation or undesirable reactions.
