って焼或されていた。A firing process up to 800 to 1400''C is essential for manufacturing building materials such as roof tiles, ceramics, and porcelain, and the dried bodies of these products are fired in shuttle kilns, tunnel furnaces, roller hearth kilns, and the like.
しかしながら、この種焼或炉のうち、殊にローラハース

したりして歩留まりが悪く、かつ高価なロールの寿命も
短いものであった。However, the rolls of this type of kiln, especially the roller hearth kiln, are continuously exposed to high heat of about 1400°C, which causes the rolls to deform, especially to curve downwards, and to make the baked bottoms look like normal ones. In addition to shrinkage, deformation, and distortion, the rolls are further distorted and deformed, resulting in poor yields and short lifespans of the expensive rolls.
〔課題を解決するための手段］

補強層主と表皮層６とから一体に形成したものである。EMBODIMENT OF THE INVENTION Below, one Example of the roller for high temperature conditions based on this invention is described in detail using drawing. That is, FIG. 1 is a perspective view showing a roller according to the present invention, and the upper one is a roller for high temperature use, and the hollow body is a cylindrical body with a length L of about 1000 to 3000 mm, and is continuously heated to a high temperature of about 1400°C. It has the strength to withstand. Its diameter D is 20 to 100
mm, and the wall thickness t is approximately 3 to 10 mm. To explain further, the roller soil for use under high heat is integrally formed from a core material 2, a main reinforcing layer, and a skin layer 6.

必要により焼威して一体化し、筒体としたものである。That is, the core material 2 is a ceramic cylinder, such as an alumina cylinder, a mullite cylinder, or a ceramic cylinder, as shown in the cross section of FIG.
It is made of one or more types of porcelain cylinders, carbon cylinders, etc., and is cast or extruded and then burnt if necessary. The reinforcing layer mainly consists of carbon fibers 4 made into a net shape or wound (in a twilled shape, a helical shape, or any other known winding method) and laminated to a thickness of about 0.5 to 3 mm. The carbon fibers 4 are long fibers, and if necessary, a carbonized adhesive 5, such as phenol resin, isocyanurate resin, melanin resin, etc., is used between the fibers to prevent the fibers from shifting or shifting during manufacturing. It functions as a heat insulating layer under high heat. The skin layer 6 is formed integrally by adhering and fixing raw materials such as alumina or mullite, and then, if necessary, is burnt and integrated to form a cylindrical body.
上述したように、本発明に係る高熱下用ローラによれば
、■高熱下に曝されてもロール自体が補強層のため殆ど
撓わまない。■ロールを３層としたため耐久性が増し、
寿命が従前に比べ２倍以上となり、高価なロールのコス
トダウンが図れる。As mentioned above, according to the roller for use under high heat according to the present invention, (1) Even when exposed to high heat, the roll itself hardly bends due to the reinforcing layer. ■Durability increases because the roll is made of 3 layers,
The lifespan is more than double compared to the previous model, and the cost of expensive rolls can be reduced.
■炭素繊維からなる補強層を芯材の外周に一体に設けた
ため、従前の９００ｎｗｎが最長であったのを３０００
ｍｍの長尺のロールを製造できるようにし、広幅焼或炉
が形或できる。■製造が容易である。等の特徴、効果が
ある。■Since a reinforcing layer made of carbon fiber is integrated around the outer periphery of the core material, the longest length of the previous model was 900nwn, but now the longest length is 3000nwn.
It is possible to manufacture rolls as long as mm, and a wide baking furnace can be formed. ■Easy to manufacture. It has the following characteristics and effects.
