摘要： PROBLEM TO BE SOLVED: To provide a monolithic refractory which is dried highly efficiently by microwave drying, has corrosion resistance inherent in an alumina-magnesia material, and hence is very effective in improving the furnace operation rate by application time shortening/lining life extension and the like, reducing standard physical units of refractory, and decreasing the number of times of repairing a lining, and so on. SOLUTION: The alumina-magnesia monolithic refractory for microwave drying is dried by the irradiation with a microwave after slip casting application and contains a refractory material mainly comprising a magnesia raw material and an alumina raw material, a binder, and a dispersant. As a coarse grain section of the alumina material, electrofused alumina containing 2-5 mass% TiO 2 in terms of a chemical component value is used. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent the decrease of ladle internal volume caused by increase of deposits (build-up), and to improve the corrosion resistance of a lining and resistance to slag permeability in the construction of a castable brick lining for molten steel ladle. SOLUTION: The side wall and bottom portions of a vessel are lined with a castable brick comprising 8-30 mass% of MgO.Al2O3-based spinel and the balance mainly alumina as a fire aggregate composition. In the case of side wall lining, the percentage of MgO.Al2O3-based spinel ultra-fine powder having mean particle diameter of below 5 μm in the whole fire aggregate composition is controlled to be 8-17 mass%, and in the case of bottom lining, zero or below 8 mass% at most. Further, the above percentage in the bottom lining is regulated to be less than that in the side wall lining by 3 mass% or more.
