Disk roll and base material for disk roll

Abstract

The present invention provides a base material for disk rolls which is a platy molded article for obtaining ring-shaped disks for use in a disk roll comprising a rotating shaft and ring-shaped disks fitted thereon by insertion, whereby the peripheral surface of the disks serves as a conveying surface, the base material comprising inorganic fibers having a crystallization temperature of 800-900° C., a filler, and a clay. Also disclosed is a disk roll which comprises disks cut out of the base material.

Claims

1. A base material for disk rolls which is a platy molded article for obtaining ring-shaped disks' for use in a disk roll comprising a rotating shaft and ring-shaped disks fitted thereon by insertion, whereby the peripheral surface of the disks serves as a conveying surface, the base material comprising inorganic fibers having a crystallization temperature of 800-900° C., a filler, and a clay.

2. The base material for disk rolls of claim 1, wherein the inorganic fibers are biosoluble fibers.

3. The base material for disk rolls of claim 2, wherein the biosoluble fibers are coated with a phosphoric acid salt, a molybdenum compound, a zinc compound, a polyamidine compound, or an ethyleneimine compound.

4. The base material for disk rolls of claim 2, wherein the content of the inorganic fibers is 5-40% by mass based on the whole amount of the base material.

5. A disk roll which comprises a rotating shaft and, fitted thereon by insertion, ring-shaped disks cut out of the base material for disk rolls of claim 1, whereby the peripheral surface of the disks serves as a conveying surface.

6. The disk roll of claim 5, which has a compression deformation of 0.05-0.3 mm when a load of 10 kgf/cm is imposed on the roll surface at 800° C.

7. The disk roll of claim 6, wherein the inorganic fibers are biosoluble fibers.

8. The disk roll of claim 7, wherein the biosoluble fibers are coated with a phosphoric acid salt, a molybdenum compound, a zinc compound, a polyamidine compound, or an ethyleneimine compound.

9. The disk roll of claim 7, wherein the content of the inorganic fibers is 5-40% by mass based on the whole amount of the base material.
