Metallurgical Nitrogen Membrane Applications

Electronics / Soldering / Laser Cutting / Cuttings / Welding / Brazing

Products
Nitrogen Membranes and Nitroswing PSA's and Nitroswing PSA's

Typical applications of GENERON® nitrogen systems for the metallurgical industry are:


  • Annealing, Carbonizing, Hardening, Sintering
  • Mining Operations
  • Laser Cutting – High purity is required to prevent oxidation of the metal being cut. High pressure versions of this system allow for the cutting of metal over 2 inches thick.
  • Wave soldering

Nitrogen Generator Systems

Frequently, nitrogen is used to purge heat treat furnaces and reflow solder baths, preventing oxidation of the metal surface and minimizing dross generation. In addition, furnaces are often blanketed to eliminate oxygen because of oxygen's tendency to react with certain metals at high temperature. Other metallurgical applications requiring oxygen-free conditions/nitrogen blanketing include:


  • neutral hardening
  • carbonizing
  • carbon nitriding
  • tempering

Many industrial lasers need nitrogen as an assist gas to help in the processing of materials. The laser cutting process uses a laser beam to melt or chemically alter the material being cut. The assist gases are used at the point where the laser interacts with the material and is used to remove the molten material and/or to chemically react with the material to produce additional thermal energy.

Depending on the process and material being cut, it is important that the assist gas is at the appropriate quality, not only to keep lasers operating reliably, but also to ensure the highest process productivity. For instance, stainless steel cutting requires some of the highest purity nitrogen - levels above 99.9%...but well within the capability of our NITROSWING® systems.

NITROSWING® PSA systems generate on-site high-purity gaseous nitrogen that provides a convenient and cost-effective solution for overall protection against impurities and oxidation for electronics and semiconductors. Typical applications include:


  • Controlling metal oxidation for electrical assembly
  • "Dry box" storage of electronic components
  • Electronic furnace, burn-in oven applications to control temperature

Oxygen Generators

Oxygen enrichment of combustion feed stream leads to...


  • Increased capacities up to 40%
  • Energy savings up to 30%
  • Reduction of flue gas and environmental impact
