摘要： PROBLEM TO BE SOLVED: To provide a microwave drying method capable of obtaining a uniform refractory tissue by rapidly discharging vaporized water vapor to the outside of a system, and restricting delivery of heat on a block surface and heat of the atmosphere in a drying furnace while maintaining high heating efficiency. SOLUTION: A microwave drying method is adapted such that a monolithic refractory with a construction water amount of 3.5 to 8% by mass is casted previously into a predetermined configuration to obtain a precasted block 3 that has already been constructed, grown, and frame demounting from a frame. Thereafter, the precast block is placed in a metal surrounding of a heating furnace 1, and the surface of the precast block is brought into contact and is covered with a heat insulating material 6. As a result, dielectric heating with microwaves radiated from a microwave apparatus 7 is achieved with a space in the surrounding used as a cavity resonator while supplying hot air at a temperature of 100 deg.C or higher from a hot air generator apparatus 10.

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
