Description

Technical Field

[0001] The present application relates to the field of metal smelting, and in particular to a water-cooled base for an electroslag remelting furnace. Background Art

[0002] The electroslag remelting furnace is an advanced smelting equipment, which is mainly used to remelt metals through the heat energy generated by electric current and high-resistance molten slag. One of the core components of the furnace is the water-cooled base, which is configured at the bottom of the electroslag remelting furnace crystallizer and forms a sealed space together with the closed crystallizer. At the beginning of the smelting process, the bottom of the ingot is located on this base, and the base needs to withstand a huge heat load.

[0003] Depending on the ingot manufacturing method, the smelting current may partially or completely pass through this base, which further increases the requirements for the base design. In order to cope with the challenges of high temperature and high current, the upper part of the base is usually designed as a water cooling system. The purpose of this cooling system is to protect the base from overheating and ensure the safety and efficiency of the equipment.

[0004] However, the existing water-cooled bases on the market have certain limitations in cooling performance. First, these bases often cannot evenly cool the entire copper base plate when ensuring cooling, or require a large amount of cooling water to achieve the ideal cooling effect. Second, the structural design of some bases, such as Figure 1 The layout shown imposes strict requirements on the positions of the water inlet and outlet pipes during installation, increasing the complexity of installation and the difficulty of maintenance. Summary of the invention

The water inlet pipe 4 and the water return pipe 5 are located in the base box 1. The upper surface of the base box 1 is provided with at least one water inlet M and at least one water return N. The water inlet M is connected to the water inlet pipe 4, and the water return N is connected to the water return pipe 5.

[0046] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.

[0047] The water-cooled base of the electroslag remelting furnace in this embodiment includes a base box 1, a copper bottom plate, a water guide plate 3, at least one water inlet pipeline 4, at least one water return pipeline 5, and a dry joint 6 connected to these pipelines. This design is used to efficiently extract heat from the crystallizer of the electroslag remelting furnace to maintain a suitable temperature of the crystallizer and its surroundings, thereby ensuring the efficiency and quality of the metal smelting process.

[0048] At the beginning of operation, the cooling water in the external cooling pipeline first enters the water inlet pipeline 4 through the dry joint 6. The dry joint 6 is designed to be easy to connect and leak-proof, ensuring the safe delivery of cooling water into the water-cooled base system. The water inlet end of the water inlet pipeline 4 is connected to the dry joint 6, and the water outlet end of the water inlet pipeline 4 is connected to the water inlet M. The cooling water is guided to the bottom edge of the copper bottom plate through the side slope of the water guide plate 3 to form a water inlet guide channel A.

[0049] The lower surface of the water guide plate 3 is in contact with the upper surface of the base box 1, and a narrow gap P is formed between the upper surface of the water guide plate 3 and the lower surface of the copper plate 2. The existence of the narrow gap P allows the cooling water to evenly cover the entire working area of ​​the copper plate 2. The cross-section of the water guide plate 3 is designed to be inverted trapezoidal, and its bottom width is greater than the maximum width between the water inlet M and the water return port N at the bottom of the copper bottom plate, which helps to optimize the distribution and guidance of the water flow.

[0050] After the cooling water flows through the narrow gap P at the bottom of the copper plate 2, it flows out from the other side edge of the bottom of the copper plate 2 to the return port N, forming a return water diversion channel B. The return port N is connected to the water inlet end of the return water pipeline 5, and the water outlet end of the return water pipeline 5 is connected to the dry joint 6. The return water diversion channel B is responsible for guiding the heated cooling water into the return water pipeline 5.

[0051] Finally, the cooling water flows to the dry joint 6 through the return pipe 5 and finally returns to the external cooling pipe. This complete cooling cycle ensures that the entire copper plate 2 is effectively cooled during the operation of the electroslag remelting furnace, preventing overheating and improving the smelting efficiency. Figure 5 As shown, in a water flow simulation environment, the water cooling base of the present application can make the water flow fully and comprehensively through the entire bottom of the copper plate, evenly taking away the heat.

[0052] Through this design, the water-cooled base of the electroslag remelting furnace can provide efficient cooling performance, ensuring the stable melting and solidification process of the metal in the furnace, thereby ensuring the quality of the final product. At the same time, the design of the system also takes into account the convenience of maintenance and the reliability of operation. The installation and maintenance process can be greatly simplified by using standardized joints and modular components.
