Meeting the challenges of tomorrow, today
Reducing production costs while improving quality, productivity and efficiency through optimization of critical resources, are just some of the challenges facing today’s metals industry. Producers must reduce the environmental impact of their operations under stringent regulations. The industry requires oxygen, nitrogen, and argon, for applications from oxygen enrichment for blast furnaces to surface protection and degasification.
Air Liquide supplies industrial gases in massive volumes via pipelines or on-site production units as well as storage infrastructure, monitoring and maintenance. We leverage our skills and innovative technologies to provide safe, reliable, and competitive gas-supply solutions for diverse needs. If your operations require medium or small volumes of industrial gases, we can deliver them to your facility in bulk or in cylinders. We are your partner for the long haul.
Air Liquide supplies industrial oxygen gas, related equipment and services to support steel making processes that utilise Electric Arc Furnaces (EAF's).
Air Liquide supplies industrial oxygen gas related to the smelting of non-ferrous metals such as aluminum, lead, brass and copper.
Air Liquide provides gases and services for reheating furnaces and heat treatment applications to create protective atmospheres for galvanizing and annealing. We serve manufacturers of products such as powder metals, wire, ingots, strip, slab, shot and other metallurgical products.
Air Liquide supplies argon and nitrogen for the ladle metallurgy furnace to stir and refine the melted steel.
Our SPAL technology helps producers of steel products to melt cleaner metals to produce castings with fewer defects, enhanced mechanical properties and lower amounts of rejects. The technology uses liquid cryogenics (argon or nitrogen), to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen, water vapor and carbon dioxide during air melting operations.
Air Liquide supplies oxy-fuel combustion solutions to maximize productivity of electric arc furnaces (EAF's) at steel mills. Oxygen is supplied for blowing down the metal in an EAF.
Air Liquide’s oxy-combustion expertise includes oxy-fuel burners, oxygen lances, low velocity oxygen injection technologies and related equipment.
Air Liquide’s oxygen, related equipment and services, support combustion applications such as ladle heating and billet/slab reheating.
We supply leading oxy-fuel burners and flue gas for the steel industry.
Air Liquide will conduct a furnace audit (flue gas analysis) as part of our gas package.
Air Liquide’s oxy-fuel and air oxy-fuel combustion units are available as rotary or reverberatory furnaces for non-ferrous metals.
We offer oxy-fuel and air oxy-fuel combustion applications along with related services such as flue gas analysis.
Developed for the metals industry, Air Liquide’s BOOSTAL™ offers oxygen supply, patented burners, and expert support for the implementation of oxy-combustion technologies for all steps in the manufacturing process.
Air Liquide’s patented Expanding Gas Air Liquide (EGAL) process, derived from SPAL technology, uses liquid cryogenics (argon or nitrogen), to reduce interactions between molten metal and atmospheric gases such as oxygen, nitrogen, water vapor and carbon dioxide during air melting operations. Our SPAL technology helps producers of non-ferrous products melt cleaner metals to produce castings with fewer defects, enhanced mechanical properties and lower amounts of rejects.
High oxygen levels are used for primary smelting. Reducing the nitrogen content of the off-gas reduces the heat losses while increasing the reaction temperature and reaction rate.
Production of non-ferrous metals (Copper, Nickel and Gold) relies on 2 main routes: Pyro-metallurgy (thermal treatment) and hydrometallurgy (chemical treatment through aqueous leaching). The choice of the relevant technology depends on numerous factors and the present share between both routes is very different from one to another metals. Nevertheless, there are signs of significant development for the hydro route compared to the conventional pyro one, which are motivated by the possibility to treat a larger range of ores (especially low grade ores) and even to re-treat dumps, the lower CAPEX, the emergence of new processes/technologies enabling higher productivity and metal recovery.
Customers in gold industry, especially when located “in the middle of nowhere” are asking for cost effective and not sophisticated processes/equipments. They also expect a global solution from their oxygen supplier in terms of injection means and monitoring, in order to optimize their process and their costs. This has been achieved within our ALDOC offer developed for partnerships with engineering companies.
Engineering Groups facilitates the promotion of our ALDOC offer. In addition, such partnerships are also opportunities to be associated to new “attractive” processes.
Gas-Liquid Mass Transfer
We supply industrial gases for casting applications such as tundish inerting and caster shrouding. Air Liquide’s patented Expanding Gas Air Liquide (EGAL) process uses liquid cryogenics, argon, or nitrogen, to reduce interactions between molten metal and atmospheric gases such as oxygen, water vapor, and carbon dioxide during air melting operations. Our SPAL technology allows foundries to melt a cleaner metal for producing castings with fewer defects, enhanced mechanical properties, and lower rejects.
We use aluminum extrusion to reduce oxygen concentration at die to control deposit reaction. In addition to nitrogen supply, we provide atmosphere analysis services for this application.
