Magneco/Metrel is a privately-owned refractory manufacturer. The company produces ceramic shapes, pumpables, gun mixes and castables for applications throughout the ironmaking, steelmaking, continuous casting and heat-treating process. Its patented no-cement castables use a unique bond system that allows for material properties relative to cement and hydratable alumina products. Magneco/Metrel has developed products that can withstand very corrosive environments. Low cement and conventional cement products are aggressively attacked by acid environments and may be destroyed in a matter of days, even at low temperatures when exposed to hydrochloric or sulfuric acid. Magneco/Metrel no-cement castables with chemistries ranging from high silica to high alumina have been developed with outstanding resistance to acid attack. Headquartered in Addison, Ill., Magneco/Metrel employs nearly 200 people.
