[0002] The refining and purification of metallic silicon is a crucial link in the production process of metallic silicon. Its main purpose is to remove impurity elements in metallic silicon and improve the purity and quality of the product. When refining and purifying metallic silicon, it is necessary to store and transport its ladles. Among them, the "hanging ladles for refining and purifying high-quality metallic silicon" disclosed in the publication number "CN218168646U" has solved the technical disadvantages of different molten iron amounts and inconvenience in turning over during the casting process. However, in actual use, ladles with similar structures still have many defects. For example, the ladles need to be preheated before use to avoid the temperature difference stress generated when the ladles come into contact with high-temperature molten iron. Most of the existing preheating methods use oven heating for preheating treatment. The oven preheats the ladles at a slow speed and requires a long time to bake them to reach the preheating temperature. In addition, the oven has a large power when preheating the ladles, which leads to a high cost when preheating the ladles. For this reason, we have designed a hanging ladles for refining and purifying metallic silicon to solve the above problems. Utility Model Content

With the help of the adjustment mechanism 2, the molten iron stored in the iron ladle can be poured out. Specifically, during the working process, the main ladle 101 can store the molten iron liquid, and the two sets of hanging plates 301 are movably installed respectively. On the mounting ring plate 401 of the outer wall of the main body 101, the top plate 302 and the suspension rod 304 between the two sets of suspension plates 301 facilitate the suspension support of the overhead crane and the ladle, so that the molten iron inside the ladle can be moved.
