Heat treatment furnaces play a crucial role in various manufacturing industries, providing a substantial amount of heat for diverse physical processes. To ensure optimal outcomes, it is essential to maintain a neutral atmosphere inside the furnace, free from gases that may interfere with the nature and results of the heat treatment processes. Hydrogen, a vital gas for creating a controlled atmosphere, is highly preferred in heat treatment furnaces. Gaztron Engineering Pvt. Ltd offers an exceptional on-site hydrogen generator that ensures a continuous supply of hydrogen for heat treatment furnaces.

Applications of hydrogen in heat treatment processes

Industrial furnaces generate a significant amount of heat through controlled combustion of fuel in a controlled atmosphere. Hydrogen is indispensable for various heat treatment processes, primarily to prevent spontaneous reactions of oxygen present in the air. The main objective of introducing hydrogen into a heat treatment furnace is to inhibit the oxidation of iron or steel.

• Bright annealing: By subjecting metals to high temperatures in a controlled hydrogen atmosphere, followed by slow cooling, bright annealing can be achieved. This heat treatment process can alter both the physical and chemical properties of metals.

• Steel annealing: Steel is heated to approximately 700°C to eliminate impurities and enhance its ductility and hardness. This process finds applications in industries where steel properties need to be modified for manufacturing purposes.

• Sintering: Sintering involves subjecting solid particles to high temperature and pressure to create solid lumps. This heat treatment process is employed to shape metal objects in unique forms.

• Brazing: Brazing involves joining two metal or ceramic objects by pouring molten compatible metal over the joint. The filler metal is heated to around 450°C to melt and evenly spread through capillary action.

• Vacuum processes: Hydrogen can serve as a residual gas in vacuum systems, as it is less prone to absorption or diffusion into metals compared to oxygen or other gases.

Gaztron Engineering's hydrogen generator produces hydrogen that can reach up to 99% purity while remaining dry. This high purity ensures the protection of heat treatment processes and prevents the interference of other gases. The continuous supply of hydrogen for heat treatment furnaces has contributed to the hydrogen plant's popularity from Gaztron Engineering.
