Fabrication of CaO–MgO–Al2O3 materials from metallurgical waste industrial residue and their potential usage in MgO–C refractories
Source abstract
Abstract
Abstract In this study, CaO–MgO–Al2O3 materials were fabricated from metallurgical industrial waste residue and industrial alumina as raw materials via solid sintering method, and their effects on the properties of low carbon MgO–C refractories were investigated. The fabricated CaO–MgO–Al2O3 materials are mainly composed of MA, CA2 and CA6 phases. The CA2-MA materials can potentially be used in low carbon MgO–C refractories. Despite a slight increase in slag corrosion and a minor reduction in the high-temperature modulus of rupture due to their low thermal expansion coefficient, the introduction of CA2-MA materials leads to improved volume stability, higher cold crushing strength, superior oxidation resistance, a lower thermal expansion coefficient and significantly enhanced thermal shock resistance.
