<p><P>PROBLEM TO BE SOLVED: To provide a refractory heat insulation material durable against long periods of combustion. <P>SOLUTION: The refractory heat insulation material contains a bundled vegetable fiber, porous refractory fine grains and an inorganic agglutination material which are to be mixed uniformly at least in a planned fixed weight percentage. The refractory heat insulation material is manufactured by adding water to the components, forming a shape under high pressure and drying. The inorganic agglutination material and the refractory fine grains are uniformly infiltrated between the vegetable fibers to cover the surface of the vegetable fibers. The heat insulation ability of the inorganic agglutination material and the vegetable fibers themselves is effectively enhanced by utilizing the refractory heat insulating performance of the porous refractory grain itself. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
