Induction Furnace

Air Products’ gas blanketing systems can help prevent metal oxidation during melting, which can help you reduce alloy costs and improve melt cleanliness and quality. If you want to boost production, our oxy-fuel systems can provide supplemental heating to rapidly melt the charge. The best solution for your process depends on many factors, such as your induction furnace’s operating parameters, goals and the current market conditions. Our applications engineers can help you implement tailored systems to meet your specific needs.

Gases

Argon

Argon, an inert gas, can provide an excellent barrier to oxidation of the melt surface.

Nitrogen

Nitrogen, like argon, can provide a barrier to oxidation of the melt surface. For alloys that are not sensitive to nitrogen pick-up, nitrogen can be a very cost effective gas to blanket melt surfaces.

Oxygen

Oxygen is required for any combustion process.  By supplementing or replacing combustion air with oxygen, overall combustion can be improved through increased heat transfer, higher flame temperatures and reduced volume of flue gases.  As a result, you can achieve greater fuel efficiencies and increase production rates.

Inert Gas Blanketing Systems

Our patented vortex sprayer or swirl cone technologies can help you blanket your melt and prevent metal oxidation and gas pick-up by displacing the atmospheric oxygen and water vapour with a dry and inert argon or nitrogen atmosphere.  By reducing metal oxidation, our proprietary technologies can help you reduce alloy costs and improve melt cleanliness and quality--resulting in less rework and scrap. Also, less slag often means less damage to the furnace liner and crucible which can lower costs over time. With our blanketing technologies, you may be able to use 50% less gas than conventional molten metal blanketing techniques. Our applications engineers can determine which blanketing technology and type of inert gas should be the most effective and economical for your operation.

Oxy-fuel Systems

Our oxy-fuel systems for supplemental heating in induction furnaces can boost production by helping you rapidly melt charge material. These systems can help you increase production rates without buying a new furnace or increasing transformer capacity. Since our systems can boost melting capacity without changes to the existing induction furnace, they can also help reduce specific electricity consumption.
