PURPOSE:To provide a disk roll having excellent heat resistance and wear resistance as well as a proper magnitude frictional coefficient by forming a sheet by heating and compressing a mixture composition where rubber chemicals, etc., are added in particular inorganic fibers, etc., and forming a disk raw material by blanking the sheet. CONSTITUTION:In a roll for a bridle roll, a fired disk 1 is fitted to a shaft 2 having a cooling water hole 2 and a rock nut 4 is tightened through a retainer ring 3. In this case, a disk raw material of the disk roll is formed by blanking a sheet which is yielded by heating and compressing inorganic fibers having no shaft excepting asbestos fibers or 20-80wt.% of the foregoing inorganic fibers and organic fibers and a mixture composition of rubber chemicals and a filler into 10-30wt.% rubber. Upon manufacture, the sheet blanked into the foregoing disk is fired at about 200 deg.C, and the fired disk 1 is inserted and fitted to many sheet shafts and it is after compressed and fixed, surface-polished. |
