Striking the right balance between profitability and competitiveness is no easy task for steel manufacturers. It calls for vigilant control over fuel consumption, resource management, efficiency, productivity and quality. We can help you meet these challenges through innovative industrial gas applications.
We offer dedicated applications for all steps in the steel mill process chain, extending from iron making and steel making through metalworking to heat treatment. Regardless of whether your production is based on ore or scrap, our solutions deliver proven efficiency gains.
Iron making
Our customized blast furnace solutions for oxygen enrichment of hot blast, Oxycoal or LNG injection or Stove Oxygen Enrichment and purging can help you increase production capacity, decrease coke consumption, use lower-cost fuels and reduce fuel consumption.
Smoke from hot metal may be reduced by CO2 or nitrogen shrouding in runners and during tapping.
Steel making
If you operate an electric arc furnace (EAF), you can rely on our cost-saving Oxyfuel solutions to produce liquid steel to your specifications. These are delivered through our partner MORE, which supplies a wide range of EAF steel making packages, including burners and injection equipment. In addition, our Oxyfuel system delivers proven efficiency gains during vessel preheating (eg: ladles, converters, tundishes or torpedos). And at the refining stage, we supply gases such as argon and nitrogen to remove hydrogen, non-metallic inclusions and unwanted trace elements.
Metalworking (rolling and forging)
Oxyfuel and High Level Lancing technologies under our REBOX® oxyfuel solutions in reheating can increase your throughput, cut energy costs and reduce emissions in the reheat and annealing furnaces.
We have perfected a wide range of heat treatment processes, all dedicated to helping you achieve the microstructure, physical properties and surface properties you need.
Annealing in a protective nitrogen atmosphere to reduce oxidation and discoloration
Carburising & carbonitriding to achieve the desired surface hardness
Galvanizing to increase strength, formability, corrosion resistance, etc. through zinc coating
Hardening, tempering and austempering to make the steel stronger and more resistant to wear
Nitriding & nitrocarburising to improve wear resistance through low-temperature treatments
Quenching and cooling to ensure the right hardness and microstructure
- Sub-zero treatments to remove retained austenite from quenched components and tools and to increase the wear resistance of tools and stabilize components.
