いる。Asbestos rolls utilize the excellent heat resistance, durability, and recovery properties of asbestos fibers, and have appropriate cushioning properties and abrasion resistance for heated materials, and can withstand temperatures of 1000° like stainless steel sheets. Although it is often used as a hearth roll even at high temperatures that reach temperatures of over 1,200 degrees Celsius, it cannot withstand use in high-temperature areas that reach temperatures of over 1,200 degrees Celsius, and due to recent asbestos pollution problems, asbestos fibers are the main raw material. Asbestos rolls require careful attention when manufacturing and using them.
High-performance heat-resistant rolls made of asbestos substitutes are being developed.

A roll made of an asbestos substitute obtained by laminating sheet materials made of the material described in No. 99062 and punched into doughnut-shaped disks, inserting an iron core, and compression molding has good durability. It has abrasion resistance, does not cause cracks, and does not cause damage to heated materials, and can be used for various purposes.
Although it can be suitably used as a transport roll for a continuous heat treatment furnace, it is difficult to provide performance comparable to asbestos rolls in terms of compression resistance and impact resistance.

It consists of installing the parts. That is, when inserting the heat-resistant sheet material into the iron core, reinforcing members are interposed between the heat-resistant sheet materials at a predetermined interval, and then the reinforcing members are inserted into the iron core and compressed using the same method as the conventional method. It is shaped into a roll.

The heat-resistant sheet material may be punched into a donut-shaped disk of predetermined dimensions using a conventional method.
なお、耐熱シート材の厚さは通常２〜１Ｏ１ＩＩ−であ

At this time, a fixing flange (2) is installed at a predetermined position from one end of the iron core. Insert one heat-resistant sheet material into the iron core to which the fixing flange (2) is fixed, then insert one reinforcing member (4), and insert the predetermined number of heat-resistant sheet materials and reinforcing members. do. The last or outer one should be a heat-resistant sheet material, and the fixing flange (2)

得ることができる。When the obtained laminate is compression molded by a conventional method, the hn strong circular member (4) is immersed in the heat-resistant sheet material (3) as shown in FIG. The hearth roll type heating furnace conveyor roll of the present invention is similar to a roll, but has dramatically improved compression resistance and impact resistance.
Obtainable.

ート材と補強用部材とを交互に設置しているが、補強用
部材の設π間隔は任意のものであり、材質、用途等を考
慮して２枚毎、３枚毎等種々の間隔で設置することがで
きることは言うまでもない。In the embodiments shown in FIGS. 1 and 2, heat-resistant sheet materials and reinforcing members are installed alternately, but the spacing between the reinforcing members is arbitrary, and may vary depending on the material, purpose, etc. It goes without saying that the sheets can be installed at various intervals, such as every two sheets or every third sheet, taking this into consideration.
補強用部材はドーナツ状円板であり、その寸法は耐熱シ
ート材の半径の１／４以上であることが好ましく、上限
は積層体を圧縮成形した後に耐性シート材に完全に没入
し、ロール表面に補強用部材が露出しないような大きさ
でなければならない。The reinforcing member is a donut-shaped disk, and its size is preferably 1/4 or more of the radius of the heat-resistant sheet material, and the upper limit is such that the reinforcing member is completely immersed in the heat-resistant sheet material after compression molding the laminate, and the roll surface The size shall be such that the reinforcing members are not exposed.
この理由は補強用部材の寸法が耐熱シート材の寸法の１
／４未満であると、ロールの耐圧縮性、耐衝撃性の向上
が不充分であり、また、ロール表面に補強用部材が露出
すると被熱材がちの熱により補強用部材の損傷が生じ、
これに伴ってロールの損傷等が起こるためである。なお
、補強用部材の厚さは０．０２〜０．５ｍｍ程度が好ま
しく、補強用部材の寸法の上限は補強用部材の厚さ、圧
縮成形条件等により異なることを理解されたい。The reason for this is that the dimensions of the reinforcing member are one of the dimensions of the heat-resistant sheet material.
If it is less than /4, the compression resistance and impact resistance of the roll will be insufficiently improved, and if the reinforcing member is exposed on the roll surface, the reinforcing member will be damaged by the heat of the heated material.
This is because damage to the rolls occurs as a result. Note that the thickness of the reinforcing member is preferably about 0.02 to 0.5 mm, and it should be understood that the upper limit of the dimension of the reinforcing member varies depending on the thickness of the reinforcing member, compression molding conditions, etc.
補強用部材の材質は金属、金属繊維、ガラス繊維、アル
ミナ繊維または炭素繊維等であり、これらからなるシー

シート（金属板）としては鉄板、ＳＵＳ薄板等を使用す
ることができる。The material of the reinforcing member is metal, metal fiber, glass fiber, alumina fiber, carbon fiber, etc., and a sheet or net-like member made of these can be used. Note that as the metal sheet (metal plate), an iron plate, an SUS thin plate, etc. can be used.
