あつた。Problems to be Solved by the Invention However, in the conventional scouring machine equipped with the above-mentioned scraping plate 1, since the scraping plate 1 is flat, it is difficult to remove oxides such as grime and slag floating on the hot water surface. When scraping out,
The oxides broke loose and escaped from both blades, resulting in poor scraping efficiency. In addition, dirt, slag, etc. tend to adhere to the reinforcing ribs that protrude from the back side of the scraping plate, and maintenance to remove the deposits is time-consuming and the service life is short.

ている。Means for Solving the Problems As a means for solving the above problems, the scraping machine of this invention has a scraping plate attached to the tip of the arm that is placed at the level of the hot metal in the metal melting furnace or molten metal container. In a scraping machine that scrapes oxides on the hot water surface to the outside by moving the scraping plate, the scraping plate has a scraping plate on both sides in the width direction of the main surface that is substantially orthogonal to the scraping direction. The scraping plate has a configuration in which a guide surface is formed that slopes at a predetermined angle forward in the scraping direction, and furthermore, the scraping plate is provided with a reinforcing rib on the rear side in the scraping direction, and the outside of the reinforcing rib is covered with a cover plate without protrusions. It is characterized by being attached.

物や溶湯の付着凝固のおそれが少ない。Function As mentioned above, the scraping plate of the scraping machine has a structure in which both sides in the width direction form guide surfaces that are inclined at a predetermined angle forward in the scraping direction with respect to the main surface.
When scraping out oxides such as dirt and slag, the action of both guide surfaces of the scraping plate prevents the oxides from escaping and the scraping operation is carried out efficiently. Furthermore, although a large force is applied to the scraping plate at high temperatures, the reinforcement ribs prevent deformation and wear. In this case, if the reinforcing ribs are exposed from the scraping plate, oxides on the surface of the molten metal and molten metal will adhere to and solidify on the uneven parts caused by the reinforcing ribs, reducing the scraping ability. (maintenance) is also troublesome. However, in the case of this invention, since the outside of the reinforcing rib is covered with a cover plate without protrusions and has a smooth surface, there is little risk of adhesion and solidification of oxides and molten metal.

After passing above the molten metal 19 and reaching the innermost part, the arm 12 is lowered and fixed almost horizontally at a height such that the lower side of the scraping plate 13 slightly sinks into the surface layer of the molten metal 19. Next,
This is done by shortening the arm 12 or retracting the scraper 11. and molten metal 1
The oxides S such as dirt, slag, and slag floating on the surface of the scraper 9 are scraped toward the scraping opening 18a.
At this time, guide surfaces 15 and 1 are provided on both wings of the scraping plate 13.
5, the oxides S such as dirt and slag are efficiently scraped up without escaping from both sides, scraped out from the scraping port 18a, and removed from the scraping port 1.
They are collected in a container 20 placed outside the furnace 8a.
