After punching a plate-shaped body with a thickness of 6 mm using ceramic fiber as the main material into a disk shape, inserting a predetermined number of this into a steel rotary shaft, and then compressing this in the axial direction to obtain a dense structure. The one whose surface is ground by a lathe or the like and finished into a roll is used. Further, the present inventors have previously proposed a disk roll using a plate-shaped body whose main material is ceramic fiber and sepiolite fiber.

高のため経済的に実用困難なものとなる。However, the above-mentioned glass disk roll has the following drawbacks. When ceramic fibers are used as the main material fiber raw material, the shot (granular) content formed in the fiberizing step of the ceramic fibers is about 50%, and if this is used as it is, the following problems occur. When a plate-shaped body is formed by using ceramic fibers having a high shot content, shots easily flow out, and thus the papermaking yield is generally low. In addition, if the obtained plate-shaped body has a large shot content, delamination is likely to occur, resulting in poor handling. Further, in a disc roll using this papermaking plate as a disc material, the shot on the surface is hard, so that there is a problem that the plate glass or the like is damaged. In order to solve the above-mentioned problem of shots, the shot content may be reduced to 5% or less by the shattering treatment, but in addition to the high cost of the ceramic fiber itself, the high cost of the shattering treatment makes it economically unpractical Will be things.

In addition, the obtained plate-shaped body has a problem that warpage occurs during drying and cracks or breaks occur during punching of the disk material.

It is a main object to provide a disk roll for glass, which has a good shot quality, a small shot content, a low cost, and a high productivity.

The gist of the present invention is to use a thin plate-shaped molded product made from a papermaking material, which is composed of 1 to 5% by weight of the agent, as a disk material.

ディスクロールの耐スポーリング性が悪くなる。The rock wool used in the present invention does not cause damage to the glass plate, and a shotless product (shot content of 5% or less) is economically preferable. Since it does not cause damage to the glass plate, it is economically practical to use 5% or less. On the other hand, the fiber diameter of rock wool is about 4-6μ
Since m is larger than about 2.5 μm of the ceramic fiber, the fiber length is preferably in the range of 80 to 300 μm. If the fiber length is 300 μm or more and is too long, delamination occurs during papermaking, and a 6 mm-thick plate cannot be produced. Also, 80μ
If it is less than m and is too short, there is no problem in papermaking, but the spalling resistance of the obtained disk roll becomes poor.

る。Mica particles, which is one of the constituent materials of the disc roll of the present invention, are mixed in an amount of 20 to 50% by weight. Mica is known to have high elasticity, slipperiness, wear resistance, heat resistance and the like, and is a material that has been industrially used for a long time in various fields. Normally, white mica K 2 Al 4 (Si 3 Al) 2 O 20 (OH) 4 is industrially used.
And gold mica K 2 Mg 6 (SiAl) 2 O 20 (OH) 4 , white mica releases crystal water from about 600 ° C., and gold mica releases crystal water from about 900 ° C. Is also 1 to 4%, less than asbestos. Since the maximum use temperature of the glass disk roll is about 650 ° C., both white mica and gold mica can be used in the present invention. Further, in the mica particles used in the present invention, 60% by weight or more has a particle size of 1
Those having a thickness of 0 to 1000 μm are preferable because they are effective in preventing the generation of wrinkles in the plate-like body. When the particle size is 1000 μm or more,
The smoothness of the surface of the bonded disc roll is deteriorated, and if the particle size is less than 10 μm and too small, the heat shrinkage of the obtained disc roll becomes large, which is not good. Since the mica particles are oriented in the manufactured plate-like body, they are oriented in the radial direction in the disc roll. Therefore, this orientation and the characteristic of high elasticity and slipperiness peculiar to mica act synergistically to form a soft and wear-resistant roll surface.

And the strength of the plate-shaped body decreases, which is not preferable.

It is possible to prevent the occurrence of peeling at the time of papermaking by blending a proper amount of.

It is limited to 5% by weight or less, which does not impair the heat resistance of.
