摘要： PROBLEM TO BE SOLVED: To provide a heat insulating monolithic refractory which suppresses the propagation and growth of crack occurring in use at from a room temperature to a high temperature of ≥1,000°C without using granular or cotton-like ceramic fiber or using porous insulating aggregate and can be used for a long period of time without being exfoliated.
SOLUTION: The heat insulating monolithic refractory is obtained by preparing refractory slurry obtained by kneading a refractory composition comprising 60-90 mass% refractory fine powder having ≤300 μm particle diameter and 10-40 mass% binder, a foaming agent and a kneading liquid having 5-220 mPa s viscosity in an amount of 25-40 pts.mass per 100 pts.mass refractory composition, jetting air into the refractory slurry in an amount of 0.3-1.2 L per 1 L refractory slurry and stirring. A construction body is formed having 70-85% apparent porosity and a pore diameter distribution in which cumulative 80% diameter is ≤500 μm.

摘要： PROBLEM TO BE SOLVED: To provide a heat insulating castable refractory for pump pressure feeding which is formed into a worked body having excellent heat insulation and fire resistance without causing clogging trouble of a pipe line by the separation of aggregate from a matrix in the pump pressure feeding with respect to a heat insulating castable refractory containing the lightweight refractory aggregate, and a wet spray working method capable of remarkably reducing the construction period without necessitating a complicated step such as a form laying work by using the heat insulating castable refractory for pump pressure feeding. SOLUTION: The heat insulating castable refractory for pump pressure feeding is prepared by kneading a refractory composition comprising lightweight refractory aggregate having bulk density of ≤1.0, refractory fine powder having ≤75 μm average particle diameter and alumina cement and a separation preventing agent with water. The blending ratio of the volume of the lightweight refractory aggregate to the volume in total of the refractory fine powder and the alumina cement is 0.65-0.85. The wet spray working method is carried out by pressure-feeding the insulating castable refractory by the pump while adding a quick setting agent. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PURPOSE:To prevent a wear lining of a ladle, which is formed of monolithic refractory, from falling off by a method wherein protruding or recessed parts are formed on the inner circumferential surface of a permanent lining and the outer surface of the wear lining is fitted on the protruding parts or in the recessed parts. CONSTITUTION:A ladle where molten metal such as molten steel is accommodated consists of an iron skin 1 as an outer shell, a permanent lining 2 built of refractory bricks on the inner surface of the iron skin 1 and a wear lining 3 formed of unshaped refractory on the inner surface of the permanent lining 2. When the permanent lining 2 is built, two or more protruding parts 4 are arranged on the bottom and side wall. The protruding parts 4 are formed of thicker refractory bricks than the refractory bricks composing the permanent lining 2. With the permanent lining 2 serving as a frame, a core is placed in the ladle and monolithic refractory is pored into the ladle while the ladle is vibrated, so that the wear lining 3 is formed with the protruding parts 4 remaining in cast-in state.

摘要： PURPOSE:To shorten drying time remarkably by evacuating a vapor extracting hole, provided on the iron skin of a refractory lining retaining vessel, upon heating and drying the refractory of the refractory lining retaining vessel. CONSTITUTION:A refractory lining retaining vessel 1 is constituted of an outer profile of iron skin 2 while a lining layer 3 is applied on the inner surface of the iron skin 2. The moisture content of the lining layer 3 is different depending on employing refractory and applying method of the same, however, a combustion burner 4 is faced to the surface of the lining layer 3 of the vessel 1 to heat and dry by flame upon heating and drying the moisture contained in the lining layer 3. Upon heating and drying the refractory of the refractory lining retaining vessel, a vapor extracting hole 5, provided on the iron skin 2 of the vessel 1, is evacuated whereby a pressure is maintained at a value lower than atmospheric pressure, moisture or water vapor, stagnated in the lining layer 3, is accelerated to move into the side of the iron skin 2 and the outflow of the moisture to the outside of the lining layer 3 is forced.
