The intermediate ladle of the continuous casting machine refers to the cladding that solidifies the cast steel into the crystallizer of the continuous casting machine during the continuous casting process. The intermediate ladle plays multiple functions in the continuous casting process.
Firstly, the intermediate package can play a role in insulation and heat preservation. In the continuous casting process, the cast steel needs to solidify at high temperatures, and the intermediate ladle can play a certain insulation effect to prevent the temperature of the cast steel from dropping too quickly and ensure the solidification quality of the billet.
Secondly, the intermediate package can also play a role in filtering impurities. In the process of casting steel, the molten iron may contain some impurities, such as oxides, sulfides, etc., which can have adverse effects on the quality of the casting billet. The filtering material in the intermediate package can effectively filter out these impurities and improve the purity of the cast steel.
In addition, the intermediate package can also play a role in preventing secondary oxidation. During the continuous casting process, molten iron needs to pass through a long distance before being injected into the crystallizer, which can easily come into contact with air and cause secondary oxidation. And the intermediate ladle can effectively isolate the molten iron from the air, prevent the occurrence of secondary oxidation, and ensure the quality of the cast steel.
In addition, the intermediate ladle can also play a role in slowing down the flow rate of molten steel. In the continuous casting process, it takes a certain amount of time for the molten iron to solidify from pouring to the crystallizer, and the intermediate ladle can slow down the flow rate of the molten steel, allowing the molten iron to fully solidify and avoiding defects in the billet.
Finally, the intermediate ladle can also play a role in evenly distributing molten iron. The shape of the crystallizer in the continuous casting machine is relatively complex, and the intermediate ladle can evenly distribute the molten iron in various areas when it flows through the crystallizer, ensuring the solidification quality of the molten iron in the crystallizer.
In summary, the intermediate ladle plays multiple functions in the continuous casting process, including insulation, filtering impurities, preventing secondary oxidation, slowing down the flow rate of molten steel, and evenly distributing molten iron. The use of intermediate ladle can improve the quality of cast steel, reduce the occurrence of defects, and improve production efficiency, which is an indispensable part of the continuous casting process.
