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 provide a hot casting repair material capable of forming a cast, without scattering, at an inclined site that needs to be repaired when thrown against the site under a situation where the operation rate is high and only a short time can be spared for repair. SOLUTION: From 5 to 30 pts.mass substance forming a carbon bond under heat and 0.1-5 pts.mass nonaqueous solvent are compounded with 100 pts.mass grain size-controlled basic refractory aggregate. The resulting composition enables moderate wetting of the basic refractory aggregate and the substance forming the carbon bond under heat by the nonaqueous solvent at compounding and kneading and results in coating of a coarse grain of the basic refractory aggregate with a fine powder. This prevents scattering of the fine powder when the composition is thrown into a furnace and crashes into a high-temperature wall furnace and enables the composition to retain the designed grain size composition and stay at the site to exert a shape retention property.

摘要： PROBLEM TO BE SOLVED: To efficiently restrain the wear of MgO-series refractory lined on a melting furnace. SOLUTION: An iron raw material for charging into the melting furnace is contained multiple oxide composed of MgO-FeO, and the melting point of this multiple oxide composed of MgO-FeO is lower compared with MgO alone. Therefore, this melting speed of MgO into slag can be made large compared with a case where MgO is added alone. Further, even in the case of directly charging the iron raw material from the upper part of the melting furnace without using a lance, the iron raw material is surely reached into the slag without flowing out to waste gas-recovering side. Therefore the wear of the MgO-series refractory lined on the melting furnace can further effectively be restrained. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：有效地抑制在熔炉上衬里的MgO系耐火材料的磨损。解决方案：用于装入熔炉的铁原料含有由MgO-FeO组成的多重氧化物，由MgO-FeO组成的多重氧化物的熔点比单独的MgO低。因此，与单独添加MgO的情况相比，可以使MgO向熔渣中的熔融速度变大。此外，即使在不使用喷枪的情况下从熔融炉的上部直接对铁原料进行充填的情况下，铁原料可靠地进入炉渣而不流出到废气回收侧。因此，能够进一步有效地抑制在熔融炉上排列的MgO系耐火材料的磨损。版权所有（C）2010，JPO＆INPIT
