Description

Technical Field

[0001] The utility model relates to the technical field of stopper rods for continuous casting tundishes, in particular to a stopper rod supporting structure for continuous casting tundishes. Background Art

[0002] The continuous casting tundish is a packaging material used to protect the molten metal during the casting process. It is usually made of ceramic material and has the characteristics of high temperature resistance and corrosion resistance. During the continuous casting process, the molten metal needs to be transmitted and protected by the continuous casting tundish. The continuous casting tundish helps to keep the temperature of the molten metal stable and prevent the invasion of oxygen and other impurities. In addition, the continuous casting tundish can also help control the speed and direction of metal flow to ensure the quality and shape of the casting. The stopper rod is an auxiliary tool used to seal the continuous casting tundish during the continuous casting process. It is usually made of ceramic material or metal and is shaped like a rod. The function of the stopper rod is to seal the molten metal in the continuous casting tundish to prevent metal loss or the entry of external impurities. The continuous casting tundish and the stopper rod are indispensable auxiliary materials and tools in the continuous casting process. They can protect the molten metal and ensure the quality of the casting.

[0003] In the prior art, the stopper rod at the tundish is generally directly suspended and lifted. Once disconnected, the stopper rod will fall directly into the tundish, making it difficult to clean up later. Based on this problem, we propose a stopper rod support structure for a continuous casting tundish. Utility Model Content
