摘要： PROBLEM TO BE SOLVED: To provide a prepared unshaped refractory having excellent adhesiveness, capable of applying for any repairing method such as spray repairing, vibration trowel repairing, capable of efficiently executing repairing work in a short time and having effect of prolonging service life. SOLUTION: The prepared unshaped refractory for repairing contains one or >=2 kinds of superfine particles selected from among silicon carbide, spinel and alumina, which has 10-0.01μm particle size, and 0.8-3wt.% alumina cement expressed in terms of CaO and is used to form a closely packed structure. When whole particles are classified into 3 particle size groups of 10-5μm, 5-1μm and 1-0.01μm size, each of the particle size construction ratio of the particles in the 3 groups to the whole particles is in the range of 20-45wt.%. The content ratio of the particles having =40wt.% SiO2 or a clay is not contained in the particle size group of

摘要： PROBLEM TO BE SOLVED: To obtain a nonslumping, high-density, low-moisture and castable composition capable of improving mechanical characteristics at high temperatures such as corrosion resistance and hot strength without basically requiring a cement as a binder or requiring a large amount thereof and to provide a method for execution thereof. SOLUTION: This nonslumping castable composition comprises the first component prepared by kneading 100 wt.% solid component comprising 0.5-5 wt.% colloidal particles of an inorganic oxide, 1-20 wt.% fluid assistant, 0.01-0.5 wt.% peptizer and the balance comprising a refractory aggregate and a refractory fine powder with water in an amount sufficient to achieve the pumpable consistency and a flocculant which is the second component added to the first component at the time of execution. Furthermore, a calcium aluminate cement in an amount so that the amount of contained calcia may be

摘要： PURPOSE:To accurately measure the atmospheric pressure generated in a construction, by inserting the leading end part of an elongated pipe whose internal space is filled with a high b.p. liquid in the construction along with a temp. detection part and connecting the rear end part thereof to a pressure detector. CONSTITUTION:The leading end part of a metallic elongated pipe 3 filled with a high b.p. liquid such as silicone oil or liquid paraffin is embedded in the cast frame 17 formed in a porous construction 15 composed of amorphous refractory or heat resistant concrete along with a thermometer composed of a thermocouple 10. The construction 15 is dried by heating the same from a surface 16. A plurality of the pipes 3 and a plurality of the thermocouples 10 are inserted according to the shape of the construction 15. The rear end parts of the pipes 3 are connected to a pressure detector 1 and the output thereof is inputted to a recorder 19. The rear ends of the thermocouples 10 are connected to a recorder 18 to continuously record pressure and temp., and the pressure and temp. generated in the execution body 15 are accurately detected. By this method, the explosion of the construction due to a rise in the pressure thereof is prevented.

摘要： Basic monolithic refractories of which the chemical composition consists essentially of, in oxide equivalence, 65%-96% by weight of MgO, 2.6%-20% by weight of ZrO2, 1.3-10% by weight of SiO2, 2% or less by weight of CaO, 0.5% or less by weight of Fe2O3 and 1% or less by weight of Al2O3, and with a mineral composition containing periclase as the main component and cubic zirconia and forsterite as sub-components, and with apparent porosity of 7% or less and bulk density of 3.2 g/cm3 or more. Basic monolithic refractories under this invention possess excellent slaking resistance, slag erosion resistance, slag penetration resistance and spalling resistance. They exhibit an excellent service life, especially as lining material for steel-making furnaces.
