Description of the Related Art Conventionally, roll cleaning apparatuses have been used in the field of cold rolling, hot-dip galvanizing and electrogalvanizing under an atmosphere in the range of 20 to 400.degree. Since the pressing method of the roll cleaning device is based on hydraulic pressure, pneumatic pressure, and motor, pressing cannot be performed in a high temperature atmosphere of 400 ° C. or higher. Therefore,
In order to clean the roll used in a high-temperature atmosphere, it is necessary to stop the equipment itself and dissipate the heat, and then polish the roll surface, which is very inefficient in terms of production efficiency. was there.

Is a plate for roll cleaning. The plate 1 is used to clean the roll by scraping off foreign substances attached to the roll. Therefore, it is the portion having the highest heat resistance and also has abrasion resistance. Reference numeral 2 denotes a weight for pressing, and the pressing pressure needs to be evenly applied in a direction perpendicular to the rotation of the roll. Therefore, the weight is evenly arranged on the roll cleaning plate. Further, during the operation of the equipment, a dish on which a weight linked to a cleaning plate is placed outside the high-temperature atmosphere furnace so that the pressure can be adjusted from outside the high-temperature atmosphere furnace to enable pressure adjustment. Reference numeral 3 denotes equipment for fixing a roll cleaning plate.

率が増加する。A roll used in a high-temperature atmosphere usually has a roll body that is not flat in order to prevent the plate being passed through from shifting in a direction perpendicular to the direction of travel of the plate.
It is in a convex state. As the roll ambient temperature increases, the degree of protrusion increases. Therefore, when the plate thickness is small, the shape of the cleaning plate can follow the roll shape due to the bending of the plate even when the degree of protrusion becomes severe. But,
As the plate becomes thicker, the rigidity increases, and the shape of the cleaning plate cannot follow the roll shape. Therefore, as the plate becomes thicker, the cleaning ability decreases, and the rejection rate due to dust adhesion increases.

Since it was 1%, it was determined that there was an improvement effect in the range of less than 0.1%, and the claimed range of the plate length was determined.

長さは５ｍｍ以上である必要がある。When the length of the plate is long, even if the degree of protrusion of the roll body becomes severe due to the rise of the roll ambient temperature,
The shape of the cleaning plate can follow the roll shape due to the deflection of the plate. However, the shorter the plate, the greater the rigidity,
The shape of the cleaning plate cannot follow the roll shape. Therefore, as the plate becomes shorter, the cleaning ability decreases, and the rejection rate due to dust adhesion increases. Therefore, the length of the plate needs to be 5 mm or more.
