摘要： PROBLEM TO BE SOLVED: To provide a molded product made of inorganic fibers, having excellent resistance to spalling and not causing surface exfoliation. SOLUTION: This molded product has the two layers cosisting of an inner layer and an outer layer. The inner layer is made of a blanket made of inorganic fiber in which fiber entanglements (or fiber loops) due to needling exist at least on the surface side of the molded product or a blanket made of inorganic fiber and produced by sewing inorganic filamentous fibers. The outer layer is made of a mixture comprising inorganic fibers, a binder and, if needed, fireproof powder.

摘要： PROBLEM TO BE SOLVED: To improve joining property in a simple constitution and simple work by disposing a laminated body of low heat-resistance fibers on the outside of a furnace of a block, disposing a laminated body of high heat-resistant fibers on the inside of the furnace, and disposing a blanket having high heat resistance and recovering property in the center part of the block and on both side faces. SOLUTION: A laminated body 1 comprising low heat-resistant fibers such as ceramic fibers is disposed on the outside of the furnace of the block. A laminated body 2 comprising high heat-resistant fibers such as alumina fibers is disposed on the inside of the furnace of the block. Further, blankets 3, 4 or mats comprising high heat-resistant fibers such as alumina fibers are disposed in the center part and both side faces of the block. Since the outside of the furnace of the block is not exposed directly to high temp., a material having rather low heat resistance is used to decrease the material cost. The high heat- resistant fiber disposed in the center and both sides of the block absorbs thermal expansion and contraction in a hot process of the low heat-resistant fiber to prevent cracks on the base, and further protects the low heat-resistant fiber on the outside of the furnace of the block from high temp.

Water is mixed with alumina silica fiber and/or alumina fiber, a binder constituted of an inorganic binder and optionally an organic binder and refractory powder to give a slurry. Then the inorganic blanket is placed on the surface of a molded equipped with a mesh and wetted with water. The mold is immersed in the slurry, the interior of the mold is sucked by a vacuum pump and an outer layer 3 is formed on the outer periphery of the mold and heat-treated at 800-1,600 deg.C.

摘要： PURPOSE: To enable a sufficient tensile strength to be attained irrespective of a simple configuration of a supporting structure by a method wherein a first supporting means made of non-organic long fiber cloth supports a non- organic fiber brancket and further a second supporting means supports an upper part of the first supporting means. CONSTITUTION: A single element 1 is comprised of four non-organic fiber branckets 2 having a substantial similar shape overlapped to each other and a cloth of non-organic long fiber is sawn with a thread as a first supporting means 3 being held and compressed between the two adjoining non-organic fiber branckets 2 positioned inside. An upper part of the first supporting means 3 is supported by the second supporting means 4. The second supporting means 4 is a rod-like supporting member made of heat-resistant metal or ceramics and this means may pass through the cloth 3 of non-organic long fiber to support it. With such an arrangement as above, its tensile strength is increased and a dangerous condition in which the partition wall is damaged is eliminated.

摘要： PROBLEM TO BE SOLVED: To provide blanket, mat block made of inorganic fiber having excellent heat resistance that can be simply and inexpensively produced and is used vertically as furnace walls and provide a furnace that is safe and has excellent heat resistance. SOLUTION: The inorganic fiber blankets or inorganic fiber mats have the same density in the vertical direction but has different densities in the transverse direction. The difference in the densities is >=0.01 g/cm3. Such inorganic fiber blankets or inorganic fiber mats are laminated to give the objective inorganic fiber blocks. In the blocks, the difference of the density is >=0.02 g/cm3. The objective furnace is formed by lining the inner walls of the furnace with a plurality of these inorganic fiber blocks.

摘要： PROBLEM TO BE SOLVED: To provide an inorg. fibered molded body uniformly hardened up to the interior and having strong thermal shock resistance and to provide the production method. SOLUTION: The inorg. fibered molded body consists of the combination of inorg. fibers, colloidal silica, a polymer flocuulant at need and refractory powder at need. The entire surfaces of the inorg. fibers are coated with the colloidal silica. The inorg. fibered molded body is produced by mixing the inorg. fibers, the colloidal silica, the polymer flocculant at need and the refractory powder at need with water to make slurry, molding and drying the resultant slurry. After the inorg. fibers are charged in the water, colloidal silica having positive surface charges is charged in the water and then colloidal silica having negative surface changes is charged.

摘要： PURPOSE:To provide refractory thermal insulating block and its working method which obviates charging of the refractory thermal insulating block after its fixing work, and can improve the safety and workability in working operation. CONSTITUTION:A refractory thermal insulating block is made such that non- organic fibers are piled up to make a laminated structure. a fixing base plate 4 having a through-pass hole 5 is arranged at a specified surface of the laminated structure. A tool hole 8 having a tubular member 1 inside of it is formed at the laminated structure and then the tool hole 8 communicates with the through-pass hole 5, the laminated structure is compressed and the compressed state of the laminated structure is maintained by a holding member 2 which can be removed. In the case that the work is to be carried out, the refractory thermal insulating block is fixed to a furnace shell and then the tubular member 1 and the holding member 2 are removed so that the tool hole 8 is substantially eliminated.

摘要： PURPOSE:To lower a shrinkage rate by adding >=1 kinds of specific additives before depositing amorphous aluminosilicate fibers to a laminally stacked body right after the formation of the fibers. CONSTITUTION:Raw materials are molten and made into fibers, by which the amorphous aluminosilicate fibers (hereafter AS fibers) having about 2 to 3mm average diameter and about 50mm length are formed. The crystalline inorg. short fibers, such as Al2O3, having 10mum to 10mm length are then uniformly mixed as the additives at 0.5 to 60wt.% of the total weight of the AS fibers and the additives with the AS fibers previously added with an antifriction material. The greater part of the short fibers are withdrawn into the laminally stacked body and the balance form the fibers 14 oriented in parallel in the traces of the needles and the fibers 15 oriented perpendicularly to the lamination direction. The fibers are uniformly dispersed in the case of small lumps 16 of a spherical shape, etc., having 1 to 5mm diameter and are oriented and dispersed in the same manner as in the respective independent addition in the case of both of the short fibers and the small lumps. Then, the shrinkage rate is lowered by the orientation of the short fibers with the laminally stacked body consisting of the mixture composed of the AS fibers and the short fibers.
