- FIG. 2 is a schematic view of the roll scraper of FIG. 1 as viewed in the direction of arrow I.
- FIG. FIGS. 3 (a) and 3 (b) are schematic views showing one embodiment of the shape of the hole provided in the scraper body.
- FIG. 4 is a schematic view showing an inclination angle of the scraper body.
- FIG. 5 is a schematic view showing a continuous siliconizing treatment line.
- FIG. 6 is a graph showing the relationship between the usage period of the scraper and the blade length.
- FIG. 7 is a graph showing the relationship between the siliconizing treatment time and the number of occurrence of pressed soot.
- FIG. 1 is a schematic view showing an embodiment of a roll scraper of the present invention.
- A is a scraper according to the present invention
- B is a hearth roll
- S is a steel strip to be passed (the arrow indicates the direction of passing of the steel strip S).
- the scraper A includes a plate-like scraper main body 1 supported on the floor, and a scratching portion 2 protruding from an upper end position of one side of the scraper main body 1.
- the scratching portion 2 is provided in a protruding manner along the upper width direction of the scraper body 1.
- the material of the scratching portion 2 is preferably made of a material having a hardness lower than that of the surface of the roll in order to prevent the roll surface in contact with the surface from being wrinkled.
- FIG. 2 is a schematic view of the scraper for a roll of the present invention of FIG. 1 as viewed in the direction of arrow I (lateral).
- a groove 4 is provided in the floor 3, and the scraper A is supported against the hearth roll B in a state where the lower end of the scraper body 1 is inserted into the groove 4.
- the scraper A supported on the rotating hearth roll B is stably supported on the floor 3 and the displacement of the scraper A causes an uneven pressing of the scratching portion 2 against the roll surface. And falling off will be prevented.
- the scratching portion 2 is held against the hearth roll B so as to be in contact with the surface of the hearth roll B. Therefore, the scratching portion 2 in contact with the roll surface scrapes the deposit on the roll surface as the roll rotates, and as a result, the deposit on the roll surface is removed.
- Such a scraper A is diagonally supported on the hearth roll B such that the scratching portion 2 is in contact with the roll surface on the rear side in the roll rotational direction as shown in FIGS.
- the disposition of the scraper A on the rear side in the roll rotation direction is because the disposition of the scraper A is stable in relation to the rotation direction of the roll, and the scraped off matter is the scraping portion 2 It is because it does not deposit between hearth rolls B.
- the scraper body 1 is provided with the opening 5.
- the weight of the scraper body 1 can be reduced.
- the load between the scraper A and the hearth roll B can be easily adjusted by changing the size of the opening appropriately. Therefore, the load between the scraper A and the hearth roll B can be made the minimum load necessary for removing the deposit, and the life of the scraper A can be extended.
- FIGS. 3A and 3B show an example of the opening 5 provided in the scraper body 1.
- the shape of the opening 5 is not particularly limited, and a plurality of openings may be provided, or one opening may be provided.
- the ratio of the opening 5 in the scraper body is preferably 19 to 40%. If the ratio is less than 19%, since the load of the scraper A is large, a load more than necessary for scraping the attached matter is applied between the scraper A and the hearth roll B, and thus the life extension of the scraper A can not be expected. On the other hand, if the ratio exceeds 40%, the load on the scraper A is small, so the attached matter can not be sufficiently scraped off.
- the plate thickness is preferably 20 to 30 mm. If the plate thickness is less than 20 mm, there is a fear that the main body may be damaged due to insufficient strength. On the other hand, if the plate thickness exceeds 30 mm, there is a possibility that the scraped nail portion 2 may be shortened in life due to an increase in weight. In addition, it is difficult to install in a narrow area, which makes installation work difficult and increases the cost.
- the inclination angle ⁇ (the inclination angle ⁇ is an angle with respect to the vertical direction of the scraper body 1; see FIG. 4) of the scraper body 1 is preferably 15 to 40 degrees. If the inclination angle ⁇ is less than 15 degrees, the load on the hearth roll B is small, and the deposit can not be sufficiently scraped off. If the inclination angle ⁇ is more than 40 degrees, the load on the hearth roll B is large, and the life extension of the scraper A can not be expected. Further, in the present invention, when the installation site of the scraper A is narrow, the inclination angle of the scraper body 1 can be changed according to the structure of the installation site.
- the ratio of the openings is reduced. If the inclination angle is large, the load is large, the ratio of the openings is large.
- the ratio of can be suitably controlled. Therefore, the design of the optimal scraper according to an installation location is possible.
- the load on the hearth roll B to 23 to 30 N and the surface pressure to 2 to 3 kPa from the viewpoint of the scraping effect of the deposit and the reduction of the wear amount of the scratching portion 2.
- the scraper by providing the opening portion in the scraper body, the scraper can be reduced in weight and the scraper can be extended in life.
- the load between the scraper and the hearth roll can be easily adjusted by changing the size of the opening appropriately.
- the scraper of the present invention one having the structure shown in FIG. 3 (a) (proportion of the opening: 21%) and one having the structure shown in FIG. 3 (b) (proportion of the opening: 36%) are used. It was. Further, in the scraper of the present invention, the inclination angle ⁇ was 17 degrees in FIG. 3 (a) and 25 degrees in FIG. 3 (b). The load on the hearth roll B is 28 N, and the surface pressure is 2.8 kPa.
- FIG. 6 is a graph showing the relationship between the usage period of the scraper A and the blade length.
- the scraper of the present invention although the blade length is about 25 mm and the amount of abrasion of the scraping portion 2 is small even after 3 months of use period, the use period of 3 months has elapsed for the conventional scraper. At this point, the blade length was 0 mm. Therefore, it can be said that the scraper of the present invention has a smaller amount of wear of the scratching portion 2 and a longer life as compared with the conventional scraper.
- the scraper of the present invention is installed in the hearth roll in the furnace of the treatment zone after the silicon treatment zone 7, the scraper of the patent document 1 (conventional scraper) is installed, and the scraper is not installed.
- the situation of occurrence of steel plate push rod was examined.
- the scraper of the present invention the one having the structure shown in FIG. 3A (the ratio of the opening portion: 21%, the inclination angle ⁇ : 17 degrees) was used (load on hearth roll B: 28 N, surface pressure : 2.8 kPa.).
- the area of the 10 m area (10 m ⁇ plate width) of each of the front end, middle and tail end in the rolling direction of the steel plate coil is visually inspected to count the number of the pressing area.
- the number of round punches was calculated, and the calculated values of the tip, middle, and tail end were averaged and evaluated.
- FIG. 7 is a graph showing the relationship between the siliconizing treatment time (h) and the number of occurrence of pressed soot (number / m 2 ). It can be said that the scraper of the present invention in which the scraper main body 1 is reduced in weight has a scraping effect of the deposit on the hearth roll equivalent to that of the conventional scraper. Therefore, weight reduction can be said to be a very effective means in prolonging the life of the scraper.
