Acier et sidérurgie
L'acier est l'un des matériaux de fabrication les plus répandus sur terre. Dans les quatre grandes catégories d'acier - acier allié, acier au carbone, acier inoxydable et acier à outils - il existe plus de 3,500 XNUMX nuances distinctes, chacune avec des propriétés thermodynamiques et chimiques fondamentalement différentes. Ceux-ci servent ensuite une gamme d'applications presque illimitée. L'industrie sidérurgique est donc un moteur majeur de la croissance économique ; rendant inestimables les processus sidérurgiques optimaux.
Chez Saint-Gobain Performance Ceramics & Refractories, nous proposons des solutions hautes performances conçues pour améliorer les indicateurs de performance clés critiques tout au long de la chaîne de fabrication de l'acier. Nous nous engageons dans le développement durable de produits réfractaires de pointe qui ajoutent une valeur multiforme aux aciéries du monde entier. Ceci est au cœur d'une feuille de route proactive vers une fabrication d'acier rentable et à faible émission de carbone.
Solutions de four : EAF et plus
La production d'acier plus écologique est un objectif permanent pour les entreprises sidérurgiques du monde entier, et cette initiative commence généralement par l'optimisation des hauts fourneaux. Nous produisons une suite de solutions de fours de précision conçues pour une résistance élevée à la corrosion et à l'oxydation à des températures extrêmes.
Nous développons actuellement des solutions pour les demandes plus élevées de réfractaires EAF qui sont attendues avec la transition vers l'acier vert. Le fours à arc électrique (EAF) a être plus flexible, recevant différentes combinaisons et quantités de ferraille, de DRI et de fer qui modifieront la composition du laitier et donc la demande en réfractaires.

Adapted Solutions
We offer tailored refractory technologies that integrate seamlessly into the demanding environments of iron and steelmaking. At Saint-Gobain Performance Ceramics & Refractories, a comprehensive range of refractory products and furnace solutions is available for iron and steelmaking equipment. Our engineered materials combine chemical stability, mechanical strength, and thermal efficiency to ensure consistency throughout every stage of production, while our high-performance refractories for DRI shaft furnaces deliver exceptional wear resistance and hydrogen corrosion protection under high-temperature reducing atmospheres. As low-carbon iron and steelmaking continues to evolve, we remain committed to innovating refractory technologies that enable producers to achieve cleaner, more sustainable operations.
Electric Arc Furnace (EAF)
EAFs are central to current steelmaking practices, where scrap and Direct Reduced Iron (DRI) produced in upstream ironmaking are melted under extreme thermal and chemical conditions. Refractory materials must remain dimensionally stable and chemically resistant in such settings, and our formulations are engineered to do exactly that. Our high-performance refractory systems support furnace stability, energy efficiency, and extended campaign life, helping bridge the transition between ironmaking and steelmaking in more sustainable production processes.
The following iron and steelmaking solutions can be applied to EAFs:
- MgO-C bricks and working linings: Dense refractory blocks made from magnesia and carbon that can be used in high-wear furnace zones such as sidewalls and slag lines to resist slag attack and thermal shock.
- Monolithic castables and repair mixes: Unshaped refractories that are applied to EAF walls and tapholes for quick gunning, shotcreting, and relining maintenance.
- Insulating and backfill systems: Lightweight refractory layers installed behind the working lining to limit heat loss and protect the furnace shell.
- Recycling technologies: Including collection, crushing, and reprocessing systems that recover spent refractories for use in new linings or slag conditioners, helping to reduce raw material waste and CO2 emissions.
Reheating Furnace
Reheating furnaces heat billets, blooms, and slabs to rolling temperatures exceeding 1200°C during iron and steelmaking. As these furnaces operate continuously at extreme heat, they require refractory linings that deliver strong insulation, uniform heat transfer, and reliable structural integrity over long service cycles. We have developed advanced refractory materials that are used in furnace linings and can deliver thermal efficiency, durability, and consistent performance throughout iron and steelmaking operations. These include Magmalox® and alumina-based refractories, fused-cast and sintered materials that offer outstanding corrosion resistance and thermal stability during cyclic heating. Magmalox®, in particular, enables steelmakers to refine control across all areas within the furnace, leading to significant improvement in furnace campaign life.
