Abstract
Description
Technical Field
[0001] The present application relates to the technical field of aluminum rod production, and in particular to a device for plugging aluminum leakage from a crystallizer. Background Art
[0002] In the metallurgical industry, a mold is often used for casting molten aluminum. A mold receives the molten aluminum and solidifies it into an aluminum ingot with a specified cross-sectional shape. The most commonly used is an oil-gas lubricated round rod mold. The aluminum rod forming process begins by melting the molten metal in a smelting furnace and quickly transferring it to a diverter trough. Once the temperature reaches the pouring temperature, the molten metal flows into the mold. The molten metal contacts the bottom starter head and the graphite rings on the mold's inner wall, forming a solidified shell. Due to solidification shrinkage, the metal gradually separates from the graphite rings on the mold's inner wall, forming a void. As the starter head moves downward at a constant speed, the ingot comes into contact with cooling water sprayed from the lower end of the mold. This secondary cooling effect causes the entire ingot to gradually solidify.
[0003] Crystallizer in related art, such as Figure 1 and Figure 2 As shown, it generally includes a cooling water pool 1 and a horizontal plate 2 bolted to the top of the cooling water pool 1. The top of the horizontal plate 2 is provided with multiple molten aluminum channels 21. Multiple tapered openings 22 are provided on both sides of the molten aluminum channels 21. A perforation 23 is provided at the bottom of each tapered opening 22. The bottom of the perforation 23 is connected to the cooling water pool 1. Below the perforation 23, an annular cooling water pipe 24 is installed at the bottom of the horizontal plate 2. The inner circumference of the cooling water pipe 24 is provided with multiple injection holes 241 in sequence along its circumference. The outer circumference of the cooling water pipe 24 is connected to a high-pressure liquid supply pipe 25. The working principle is as follows: molten aluminum is first injected into the molten aluminum channel 21. The molten aluminum in the molten aluminum channel 21 then flows through the perforations 23 toward the cooling water pool 1. As the molten aluminum flows from the perforations 23 to the bottom, condensate is sprayed from the injection holes 241, slowly solidifying the liquid aluminum from the outside. This forms the initial aluminum rod. The initially formed aluminum rod then enters the cooling water pool 1 for cooling and forming.
[0004] When the aluminum liquid flows downward through the tapered opening 22, if there is a problem with the condensate sprayed from the injection hole 241, or other problems cause the aluminum rod to leak during the initial solidification process (not solidified well), then because it is a tooling, the aluminum liquid in the aluminum liquid channel 21 will continue to flow from the damaged part of the initially formed aluminum rod into the condensate. Since a large amount of aluminum liquid flows in, it is easy to cause an explosion. However, when the above-mentioned crystallizer leaks, it is inconvenient to plug the tapered opening 22.
