Description

Technical Field

[0001] This invention belongs to the field of metallurgical continuous casting equipment; in particular, it relates to a crystallizer cooling water optimization system with a distribution ring flow equalization structure. Background Technology

[0002] In continuous casting, the crystallizer, as a crucial initial stage in billet formation, directly impacts billet quality and production efficiency through its cooling effect. Traditional crystallizer cooling systems often employ a single inlet for direct water supply, a design with several insurmountable drawbacks. Firstly, the high-speed influx of water into the crystallizer from a single inlet creates a strong impact near the inlet, resulting in varying water flow velocities in the copper tubes. This uneven cooling of the copper tubes accelerates wear, shortens the crystallizer's lifespan, and increases maintenance costs and downtime. Secondly, uneven cooling of the copper tubes further leads to uneven internal stress in the billet, causing defects such as cracks. It also results in inconsistent solidification rates in different parts of the billet, affecting overall dimensional accuracy and the uniformity of its internal structure.

[0003] With the steel industry's increasingly stringent requirements for billet quality and its urgent need to improve production efficiency, there is an urgent practical need to develop a crystallizer cooling inlet and outlet water optimization system that can effectively solve the shortcomings of traditional cooling systems and achieve uniform distribution and precise control of cooling water flow. Summary of the Invention

[0004] This invention aims to design a cooling water optimization system for a crystallizer with a distribution ring flow equalization structure. Through an innovative water inlet distribution structure control mechanism, it effectively solves the problems of large water inlet flow impact and uneven cooling in traditional cooling systems, achieves uniform cooling intensity in all areas inside the crystallizer, effectively improves the internal cooling effect of the crystallizer, significantly improves the quality of the cast billet, extends the service life of the crystallizer, and improves the stability and economy of continuous casting production.

[0005] This invention is achieved through the following technical solution:

[0006] This invention relates to a crystallizer cooling water optimization system with a distribution ring flow equalization structure, comprising: a crystallizer body 1, a water guide groove 2, a water flow distribution ring 3, a crystallizer body shell 4, a crystallizer water inlet 5, a crystallizer water return hole 6, a crystallizer foot roller water inlet 7, and a crystallizer shell opening 8.

[0007] in,

[0008] Water guide channel 2 is connected to the water inlet 5 of the crystallizer;

[0009] The water distribution ring 3 is set on the outer wall of the crystallizer body shell 4 and is connected to the water guide channel 2;

[0010] Cooling water enters the water guide channel 2 through the crystallizer inlet 5. Under the guidance of the water guide channel 2, the water flow is directed to the water distribution ring 3.

[0011] Inside the water distribution ring 3, the water flow forms a circulating motion, effectively reducing the velocity gradient of the water flow through centrifugal force, thereby achieving uniform flow velocity. This design cleverly disperses the originally concentrated water flow into multiple uniform water flows while keeping the total water volume constant. This not only effectively reduces the local impact intensity but also avoids differences in cooling effect caused by uneven impact force.

[0012] Preferably, at least four openings are provided at the connection between the water flow distribution ring 3 and the outer wall of the crystallizer body shell 4; the total area of ​​the water passage holes provided on the shell is designed to be no less than 1.5 times the total inlet cross-sectional area, which effectively reduces flow rate loss and significantly improves the cooling effect, thereby ensuring the operating efficiency and stability of the entire system.

[0013] Preferably, the opening communicates with the cooling copper pipe. The opening is designed to ensure that the cooling water entering the water distribution ring 3 can evenly enter the cooling copper pipe inside the housing.

[0014] Preferably, the spacing between the openings is equal to achieve uniform flow distribution.

[0015] Preferably, the outer diameter of the water flow distribution ring 3 is smaller than the inner diameter of the crystallizer vibration frame, which ensures the compatibility and ease of installation of the equipment while fully considering the installation requirements of the crystallizer.

[0016] Preferably, both the water distribution ring 3 and the crystallizer body shell 4 are made of stainless steel, which is compatible with the electromagnetic stirring environment of the crystallizer and can effectively extend the service life of the crystallizer.

[0017] The present invention has the following advantages:

[0018] (1) The present invention adds a water guide channel and a water flow distribution ring. Through the synergistic effect of the water guide channel and the water flow distribution ring, the uniform distribution and flow rate regulation of the cooling water flow are realized, which effectively solves the problems of uneven flow rate and excessive local impact in the cooling process of traditional crystallizers; and provides a reliable technical guarantee for improving the solidification quality of metal and extending the service life of equipment.
