Heat treatment involves controlling numerous parameters in order to achieve specific metallurgical properties in a given material. We offer technologies and in-depth know-how to enable precision control of some of the most critical parameters within the various heat treatment processes. In addition, we provide the full range of gases to form furnace atmospheres.

Annealing

Our CARBOFLEX® nitrogen-endogas solution offers a nitrogen-based atmosphere system in combination with an external endogas generator. This solution proves that nitrogen-based atmosphere systems and endogas make a great combination. CARBOFLEX can be used to create furnace atmosphere zones with varying compositions to meet the requirement of specific alloys being treated.

Highlights:

• Avoids decarburisation through carbon-neutral atmosphere
• Enables high surface quality (bright surface, no carbon deposits)
• Achieves high level of safety by using a minimum volume of flammable   gases and a nitrogen-based safety purge function
• Reduces costs by minimising total gas consumption, scrap and reworking

Furnace Brazing

Improving the quality of brazed joints while reducing total atmosphere costs in furnace brazing

Furnace brazing requires atmospheres to facilitate excellent braze joints and better surface quality in mass production. Our technologies enable companies to control and optimise furnace conditions to achieve higher productivity and increased surface quality. In addition, optimised atmosphere compositions reduce total costs.

CARBOTHAN® is a nitrogen/methanol-based atmosphere system, which generates a very flexible, high-quality atmosphere for carburising, neutral hardening, annealing and sintering of steel. The CARBOTHAN atmosphere system includes methanol storage and supply, flow control, injection and distribution to the furnace.

Highlights:

• Reduced energy consumption and floor space requirements
• Shorter conditioning and shut-down times
• Easy reduction of gas consumption during idle times
• No resources needed for supervision and maintenance
• Safe gas supply and distribution system
