APPLICATIONS
Heating non-ferrous metals, such as aluminum, copper, and titanium, involves the use of gases like argon, nitrogen, oxygen, and hydrogen to optimize the process and improve product quality. Argon is used to create an inert atmosphere, preventing oxidation and contamination during melting and casting. Nitrogen is employed similarly to argon, providing an inert environment that protects the metal from reacting with atmospheric gases. Oxygen is used in controlled amounts to remove impurities through oxidation, enhancing the purity of the final metal. Hydrogen is utilized to reduce oxides and other impurities, improving the metal’s properties. These gases are essential in ensuring the efficient heating, melting, and refining of non-ferrous metals, resulting in high-quality products.

Non-ferrous metals are metals that do not contain significant amounts of iron. Examples include aluminum, copper, zinc, lead, nickel, and titanium. These metals are valued for their properties such as low weight, higher conductivity, non-magnetic nature, and resistance to corrosion.
Heating in non-ferrous metals production involves melting, refining, and heat treating metals to achieve desired properties such as hardness, strength, ductility, and electrical conductivity. This process is essential for shaping and enhancing the performance of the final products.
Industrial gases are used to achieve high temperatures necessary for melting and refining, create controlled atmospheres to prevent oxidation, and improve the efficiency and quality of heat treating processes. They also help in alloying and degassing.
Common gases include oxygen (O₂), natural gas (methane, CH₄), nitrogen (N₂), argon (Ar), and hydrogen (H₂). These gases support combustion, create protective atmospheres, and aid in refining and degassing processes.
Oxygen is used in oxy-fuel combustion to achieve higher flame temperatures, improve fuel efficiency, and reduce emissions. It is also used in processes like oxidative refining to remove impurities from molten metals.
Natural gas is used as a fuel source for furnaces and heaters due to its high energy content and efficiency. It is commonly used in conjunction with oxygen to achieve the required temperatures for melting and refining.
Yes, nitrogen is used to create inert atmospheres during melting and heat treating processes to prevent oxidation and contamination of the metal surface. It is also used in annealing and solution treatment processes.
Industries such as aerospace, automotive, electronics, construction, and manufacturing commonly use gas-assisted heating for producing high-quality non-ferrous metal products.
