る。2. Description of the Related Art In a high-temperature continuous heat treatment furnace having a hearth roll in a furnace for passing steel sheets, such as a continuous siliconizing furnace for manufacturing a high silicon steel strip, a lower surface of the steel strip and a hearth are used. Oxidation scale of steel strip adheres and accumulates on the surface of the hearth roll due to contact with the roll, or refractories in the furnace fall off and scatter, and products in the furnace adhere and accumulate on the surface of the hearth roll. In addition, there is a problem that these deposits cause press flaws in the steel strip heated to a high temperature.

はない。Therefore, it is conceivable to attach a scraper to the hearth roll for scraping off such deposits from the roll surface. However, the inside of a furnace such as a continuous siliconizing furnace has a very high temperature. Since it is below, it is extremely difficult to install mechanical means such as pressing the scraper against the roll surface in the furnace in terms of heat resistance and durability. Therefore, in order to remove the deposits on the surface of the hearth roll, the hearth roll is rotated with the steel strip threading stopped, and the deposits on the roller surface are removed by slipping the hearth roll against the steel strip. The only effective method is to scrape or open the furnace to clean the hearth roll surface.

It is necessary to keep the temperature low, and a great loss in productivity is inevitable. Therefore, an object of the present invention is to appropriately scrape off the deposits attached to a roll used at a high temperature, such as a hearth roll in a continuous heat treatment furnace, and have a very simple structure for a long time at a high temperature. An object of the present invention is to provide a scraper that can be used without impairing the function.

ール間に堆積しない。 In the scraper, the scraper in contact with the roll surface scrapes off the deposits on the roll surface as the roll rotates, and removes it. The scraper of the present invention has only a scraper body and a claw portion protruding from the scraper body, and has a simple structure in which the scraper is only leaned against a roll.
Since there are no mechanical moving parts or complicated mechanical parts whose functions are degraded by the influence of heat when used at high temperatures around 1200 ° C, long-term operation at high temperatures by selecting appropriate materials Can be used without loss. Further, in terms of material, the scraper of the present invention has an extremely simple structure as described above, and thus has excellent heat resistance, corrosion resistance, etc., and has mechanical properties in terms of workability and strength. It can be made of a material that cannot be used at all as a material constituting a complicated moving part or a complicated mechanism part. Therefore, for example, even in a severe furnace environment such as extremely high temperature and containing corrosive gas, the furnace It can be applied as a scraper for the inner hearth roll. Also,
The scraper is located on the rear side in the roll rotation direction
Therefore, the scraper is stabilized in relation to the rotation direction of the roll.

Are configured to be larger than the width of the hearth roll surface that makes contact. Note that the material of the claw portion 2 is preferably a material having a hardness lower than that of the roll surface in order to prevent scratches on the contacting roll surface. Such a scraper A is leaned obliquely against the hearth roll B such that the claw portion 2 is in contact with the roll surface on the rear side in the roll rotation direction as shown in the figure. The reason why the scraper A is arranged on the rear side in the roll rotation direction in this manner is that this arrangement stabilizes the scraper A in relation to the rotation direction of the roll, and the scraped-off attachments This is because it does not accumulate between the hearth rolls B.

にスクレーパ本体１の下端を差し込む構造を採用した。Test Example As shown in FIG. 5, a high silicon steel strip is manufactured in a continuous siliconizing furnace having a heating zone 8, a siliconizing zone 9, a diffusion zone 10 and a cooling zone 11 from the inlet side. In this case, SiCl 4 supplied to the siliconizing zone 9 reacts with trace amounts of oxygen and moisture in the furnace atmosphere to generate silica (SiO 2 ), which adheres to the hearth roll in the furnace after the siliconizing zone. There is a problem in that the high silicon steel strip is deposited to cause a press flaw. Therefore, the state of the occurrence of press flaws in the steel strip was examined when the scraper of the present invention was installed on the hearth roll in the furnace in the treatment zone after the siliconized treatment zone and when the scraper was not installed at all. The scraper of the present invention has a structure shown in FIG. 2 and a structure shown in FIG. 3, and each of the scrapers has a structure in which the lower end of the scraper main body 1 is inserted into a groove provided on the floor as shown in FIG. Adopted.

効果が得られていることが判る。FIG. 6 shows the result. When the scraper of the present invention is installed, the adhesion and deposits on the roll surface are effectively scraped off. It can be seen that the generation of flaws is significantly reduced. Further, it can be seen that the scraper of the present invention having the structure of FIG. 3 in which the auxiliary plate is provided has a more excellent scraping effect.

積しないという利点もある。 According to the scraper of the present invention described above, it is possible to appropriately scrape off the deposits adhered to a roll used at a high temperature such as a hearth roll in a continuous heat treatment furnace, and it is extremely simple. With a simple structure, it can be used for a long time at a high temperature without impairing its function.
In particular, the scraper of the present invention consists only掻爪portions which are scraper body and projecting thereto, which has a simple structure only leaned to the roll, at a high temperature of about 1200 ° C.
Since there are no mechanical moving parts or complicated mechanical parts whose functions are degraded by the influence of heat even when used in the environment, by selecting an appropriate material, the function will not be impaired for a long time at high temperatures. Can be used. In addition, since the scraper of the present invention has an extremely simple structure as described above, it has excellent heat resistance and corrosion resistance, but has mechanical movable parts and complicated mechanical parts in terms of workability and strength. It can be made of materials that cannot be used as a constituent material at all, so it can be applied as a scraper for hearth rolls in furnaces even in severe furnace environments where extremely high temperatures and corrosive gases are contained. It is. Also, scraper
Is located on the rear side in the roll rotation direction.
The scraper stabilizes in relation to the rotation direction of the
At the same time, the scraped off deposits collect between the claw and the hearth roll.
There is also the advantage of not stacking.
