background
[2]
A grain-oriented electrical steel sheet with magnetic properties with low iron loss and high magnetic flux density is required in order to reduce power loss and improve efficiency of electrical devices such as transformers. A magnetic domain refining process is needed to improve iron loss by creating grooves by applying a high-power continuous wave laser beam that can form grooves on the surface of grain-oriented electrical steel sheet.
[3]
However, in this method for permanent magnetic domain refining, grooves must be formed on the surface of the steel sheet, and in this case, various types of foreign substances such as particles, chips, spatter, and fume are formed on the surface of the steel sheet. .
[4]
These foreign substances must be removed immediately after they occur, and if they are not removed immediately after they are generated, there is a problem of contaminating surrounding facilities and worsening the working environment.
[5]
In particular, the spatter is approximately spherical in shape, has a size ranging from several hundred nm to several tens of um in diameter, and consists of Fe, Si, C, and O. If the optical system is contaminated, the performance is rapidly deteriorated, and there is a problem in that it is impossible to secure the grooving quality and productivity.
[6]
In addition, after these spatters are fused to the surrounding equipment, grow and form a lump, they fall on the surface of the steel plate, causing plate breakage, and causing defects on the surface of the steel plate by being caught between the rollers of the rear end equipment.
[7]
Therefore, there is a need for research on a foreign material removal device capable of improving the above-described problems or limitations and an electrical steel sheet manufacturing facility including the same.

[63]
That is, while disposing the rod member 211 as far as possible from the slit hole 111 formed in the cooling block member 110 of the hood unit 100, which is the laser (L) irradiation area where the spatter is intensively formed. The rod member 211 is disposed far from the slit hole 111 so that the scraping operation by the scraper 220 is performed in a wider area of ​​the cooling block member 110 of the hood unit 100 . In order for the scraper part 220 to be uniformly disposed on the cooling block member 110 , the scraper part 220 is disposed to be biased toward the rod member 211 .

Since they are coupled, in order for the scraper body 221 to be evenly disposed between the slit hole 111 and any one of both ends of the cooling block member 110, the rod member ( 211) must be biased.
[76]
For example, when the expansion and contraction actuator 210 is coupled to the cooling block member 110 to be biased to the left, the scraper body 221 is coupled to the rod member 211 of the expansion and contraction driving part 210 to be biased to the right. will become

Furthermore, the scrub member 216 is formed to correspond to the diameter of the rod member 211 so that only the other end is in contact with the outer surface of the rod member 211, and is in the form of a trumpet whose diameter increases toward one end. There is an advantage in that only foreign substances such as spatters attached to the rod member 211 can be removed by scraping without affecting the reciprocating movement of the rod member 211 .
