Abstract

A base material for a disk roll, the base material including:
5 to 9 wt % of ceramic fibers, 20 to 40 wt % of kibushi clay, 2 to 20 wt % of bentonite and 40 to 60 wt % of mica.

First claim

The invention claimed is:

1. A base material for a disk roll, the base material comprising:
5 to 9 wt % of ceramic fibers, 20 to 40 wt % of kibushi clay, 2 to 20 wt % of bentonite and 40 to 60 wt % of mica,
wherein the amount of shots having a diameter of 45 μm or more in the ceramic fibers is 5 wt % or less.

2. The base material for a disk roll according to claim 1 , wherein the ceramic fibers comprise 30 wt % or more and less than 70 wt % of alumina and more than 30 wt % and 70 wt % or less of silica.

3. The base material for a disk roll according to claim 1 , which further comprises pulp and starch.

4. A method for producing a base material for a disk roll, the method comprising:
providing ceramic fibers comprising 30 wt % or more and less than 70 wt % of alumina, more than 30 wt % and 70 wt % or less of silica, and 5 wt % or less of shots having a diameter of 45 μm or more;
mixing water, the ceramic fibers, kibushi clay, bentonite and mica to produce an aqueous slurry comprising, in solid content, 5 to 9 wt % of the ceramic fibers, 20 to 40 wt % of the kibushi clay, 2 to 20 wt % of the bentonite, and 40 to 60 wt % of the mica; and
flowing the aqueous slurry in a forming chamber or a forming mold, followed by water filtration to produce a sheet.

5. A disk roll which comprises ring-like disk materials obtained from the base material according to claim 1 .

6. A method for producing a disk roll, the method comprising:
providing a base material according to claim 1 ;
punching out a plurality of ring-like disk materials from the base material according to claim 1 ; and
fitting by insertion the plurality of ring-like disk materials into a shaft, followed by compression to obtain a roll-like laminate.

7. A method for producing glass comprising conveying a glass melt by means of the disk roll according to claim 5 , and cooling the glass melt.

8. The base material for a disk roll according to claim 2 , which further comprises pulp and starch.

9. The base material for a disk roll according to claim 1 , which further comprises pulp and starch.

10. The base material for a disk roll according to claim 2 , which further comprises pulp and starch.

11. A disk material for a disk roll, the disk material comprising:
5 to 9 wt % of ceramic fibers, 20 to 40 wt % of kibushi clay, 2 to 20 wt % of bentonite and 40 to 60 wt % of mica,
wherein the amount of shots having a diameter of 45 μm or more in the ceramic fibers is 5 wt % or less.

12. A method for producing a disk material for a disk roll, the method comprising:
providing a base material according to claim 1 ; and
punching out a ring-like disk material from the base material according to claim 1 .

13. The base material for a disk roll according to claim 1 , wherein the base material comprises 6 to 8 wt % of the ceramic fibers, 28 to 38 wt % of the kibushi clay, 5 to 14 wt % of the bentonite, and 40 to 54 wt % of the mica, and
wherein a total amount of the ceramic fibers, kibushi clay, bentonite and mica is 90 wt % or more.

14. The base material for a disk roll according to claim 1 , wherein the base material comprises 6 to 8 wt % of the ceramic fibers, 28 to 38 wt % of the kibushi clay, 5 to 14 wt % of the bentonite, 40 to 54 wt % of the mica, 2 to 10 wt % of pulp, and 1 to 10 wt % of starch, and
wherein a total amount of the ceramic fibers, kibushi clay, bentonite and mica is 90 wt % or more.

15. The base material for a disk roll according to claim 1 , wherein the base material comprises 6 to 8 wt % of the ceramic fibers, 28 to 38 wt % of the kibushi clay, 5 to 14 wt % of the bentonite, 44 to 54 wt % of the mica, 2 to 10 wt % of pulp, and 1 to 10 wt % of starch, and
wherein a total amount of the ceramic fibers, kibushi clay, bentonite and mica is 90 wt % or more.

16. The base material for a disk roll according to claim 1 , wherein the base material comprises 6 to 8 wt % of the ceramic fibers, 28 to 38 wt % of the kibushi clay, 5 to 14 wt % of the bentonite, 44 to 54 wt % of the mica, 5 to 10 wt % of pulp, and 1 to 4 wt % of starch, and
wherein a total amount of the ceramic fibers, kibushi clay, bentonite and mica is 90 wt % or more.

17. The base material for a disk roll according to claim 2 , wherein the base material comprises 6 to 8 wt % of the ceramic fibers, 28 to 38 wt % of the kibushi clay, 5 to 14 wt % of the bentonite, and 40 to 54 wt % of the mica, and
wherein a total amount of the ceramic fibers, kibushi clay, bentonite and mica is 90 wt % or more.

18. The base material for a disk roll according to claim 2 , wherein the base material comprises 6 to 8 wt % of the ceramic fibers, 28 to 38 wt % of the kibushi clay, 5 to 14 wt % of the bentonite, 44 to 54 wt % of the mica, 5 to 10 wt % of pulp, and 1 to 4 wt % of starch, and
wherein a total amount of the ceramic fibers, kibushi clay, bentonite and mica is 90 wt % or more.
