Description

Technical Field

[0001] The utility model relates to the technical field of slag removal equipment, in particular to a metal smelting slag removal tool. Background Art

[0002] During the smelting process of metals, such as molten aluminum and iron, if excessive slag is present, it not only affects the precise control of the composition and impurities of the molten aluminum and iron, leading to large fluctuations in product quality, but also increases flux consumption and prolongs smelting time, further affecting smelting efficiency. Therefore, slag removal during smelting is extremely important. Currently, the most commonly used cleaning tool is the slag rake, which is mostly composed of solid iron plates and iron bars. Its simple structure makes it difficult to use. Researchers are continuously developing this cleaning tool.

[0003] Chinese patent application number 201910099394.3 discloses a high-efficiency slag plate for molten iron slag removal, comprising a connecting portion and a working portion. By matching the slag plate's structural dimensions with those of the molten iron ladle, providing a "saddle" structure for the slag plate, and optimizing its dimensions, the patent aims to improve the overall technical and economic performance of molten iron slag removal, including increased slag removal efficiency, reduced iron loss, shortened slag removal time, reduced slag removal frequency, and extended slag plate service life. However, in practical applications, such as during aluminum alloy smelting, when oxidized slag is produced by contact between molten aluminum and air and requires prompt cleaning, the aluminum slag removed using this improved slag plate or a traditional slag rake contains a high amount of molten aluminum, making it difficult to effectively address the problem of excessive residual aluminum in the slag, resulting in material waste and urgent need for improvement.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0022] Example 1

[0023] See also Figures 1 to 3 shown.

[0024] The metal smelting slag removal tool described in the present invention includes a slag removal rod 1 and a slag removal plate 2. The slag removal plate 2 includes a connecting portion 21 and a working portion 22. In a preferred embodiment, the connecting portion 21 and the working portion 22 are integrally formed, and the thickness of the working portion 22 is 20 to 30 mm. In this embodiment, the thickness of the working portion 22 is about 25 mm, which has high strength and can well meet the needs of slag removal under high temperature conditions. The working portion 22 is a trapezoidal plate structure that is narrow at the top and narrow at the bottom. Therefore, during the slag removal process, while the slag removal range can be expanded as much as possible, most of the liquid such as molten iron or molten aluminum can pass through the top of the working portion 22 more quickly, reducing the slag removal resistance. The multiple filter holes 222 on the working portion 22 are evenly distributed, which can further filter out the liquid in the metal slag, further reduce the slag removal resistance, and reduce the liquid residue in the metal slag, thereby reducing material loss. In some preferred embodiments, such as Figure 2 and Figure 3 As shown, the multiple filter holes 222 provided on the working portion 22 are tapered hole structures, and the inner diameters of the filter holes 222 increase successively along the direction of liquid filtration. In a preferred embodiment, the inner diameter of the hole at the inlet of the filter hole 222 is 8 to 15 mm, and the inner diameter of the hole at the outlet of the filter hole 222 is 20 to 30 mm. Specifically in this embodiment, the inner diameter of the hole at the inlet of the filter hole 222 is 10 mm, and the inner diameter of the hole at the outlet of the filter hole 222 is 25 mm. By setting up the tapered hole structure, it is possible to ensure that the metal slag is fully scraped out while better ensuring that liquids such as molten iron or molten aluminum pass quickly through the working portion 22 to prevent blockage, thereby further improving the working efficiency of filtration.

[0025] The connecting portion 21 is provided on the top of the working portion 22 , and is connected to the scraper bar 1 . In this embodiment, the connecting portion 21 is vertically arranged and fixedly connected to the scraper bar 1 .

[0026] Example 2

[0027] In this embodiment, the difference from the embodiment 1 is that the connection portion 21 is connected to the scraper bar 1, and the connection angle between the connection portion 21 and the scraper bar 1 is adjustable. Figure 4As shown, the scraping bar 1 is provided with a U-shaped mounting groove 11 at one end near the scraping plate 2. A corresponding mounting block 23 is provided on the connecting portion 21 of the scraping plate 2. The mounting block 23 matches the mounting groove and is secured to the mounting groove via a bolt assembly 3. By adjusting the angle between the mounting block 23 and the mounting groove up and down and then securing the mounting block 23 with the bolt assembly 3, the scraping bar 1 can better meet the needs of scraping in different positions and corners in actual application. As a further improvement, the scraping bar 1 is a telescopic rod, which better adapts to the needs of smelting furnaces of different specifications, making it more flexible and widely applicable.
