Description

Technical Field

[0001] The utility model belongs to the technical field of accessories of continuous casting equipment, and in particular relates to a centering device for a water outlet of a tundish of a continuous casting machine. Background Art

[0002] During the production process of the continuous casting machine, the centering operation of the tundish water outlet and the crystallizer is one of the key steps to ensure the stability of the continuous casting process and improve the quality of the ingot. The traditional method of centering the tundish water outlet of the continuous casting machine mainly relies on the arc surface of the lower water outlet and the arc surface of the upper water outlet in the tundish to achieve positioning. However, under the influence of the complex and changeable flow field of the molten steel in the crystallizer, this fixing method is often difficult to ensure long-term stable alignment and is prone to deviation. Once the water outlet deviates from the center position of the crystallizer, it will not only increase the risk of bonding and steel leakage, but also affect the surface quality and internal structure of the ingot, and in severe cases may even lead to production interruption.

[0003] In addition, the existing centering operation process is cumbersome and inefficient. Before each tundish is started, at least two people are required to work together to complete the centering of the water outlet. One person is responsible for fine-tuning the tundish mechanism, while the other needs to stand at the top of the crystallizer and make fine adjustments by observation and experience. This operation method is not only time-consuming (usually 2-4 minutes), resulting in the loss of temperature in the inner cavity of the tundish, affecting the startup efficiency and the quality of the ingot, but also unreasonable manpower occupation, low operating efficiency, and increased production costs.

[0004] Therefore, in view of the above problems existing in the prior art, technicians in this field urgently need to develop a more efficient and accurate device for centering the water outlet of the tundish of a continuous casting machine to simplify the centering operation process, improve the operating efficiency, and ensure the accurate centering of the water outlet and the crystallizer, reduce the risks of bonding and steel leakage, and improve the quality of the casting and the overall operating efficiency of the continuous casting machine. In this context, the utility model proposes a device for centering the water outlet of the tundish of a continuous casting machine, which aims to solve the deficiencies in the prior art through innovative design and promote the further development of continuous casting technology.
