Abstract
PURPOSE:To develop a high heat resistant roll for conveying billets in a heating furnace by laminating, fitting and fixing doughnut-shaped sheets consisting of crystalline alumina fibers, sepiolite, org. fibers, inorg. binder and org. binder around a metallic pipe. CONSTITUTION:Water is added to 5-50wt.% sepiolite having >=20 aspect ratio and the mixture is subjected to a beating treatment to prepare a slurry. The crystalline alumina fibers are added at 50-90wt.% thereto and the org. fibers of 0.5-1 denier such as natural pulp and polypropylene are added thereto, then the mixture is stirred. 2-5wt.% org. binder such as polyacrylamide and 5-40wt.% inorg. binder such as mullite are added into this slurry and the slurry is stirred. This slurry is made into a thin sheet of 1,000g/m<2> weight. Plural sheets of such thin sheets are laminated and pressed to form a plate having >=0.5g/cm<3> density. The plate is blanked to a doughnut shape and dried. Many sheets of the sheets 2 are laminated and fitted onto the metallic pipe 1 and are fixed by means of washers 3 and nuts 4. The conveying roll having the excellent heat resistance for the heating furnace is thus produced.
