Description

Technical Field

[0001] The utility model relates to the technical field of steel ingot production, in particular to a temperature control device for an alloy steel ingot continuous casting machine. Background Art

[0002] Continuous casting machine is a device used for continuous casting of metals, mainly used to produce metal materials such as steel, copper, and aluminum. The continuous casting machine injects molten metal into a mold and then solidifies the metal into a billet or plate of the desired shape during the cooling process. Continuous casting technology can improve production efficiency, reduce energy consumption, and produce castings of better quality, so it has been widely used in the modern metal processing industry.

[0003] In the process of producing steel ingots, the crystallizer inside the continuous casting machine can cool the liquid metal to below the solidification temperature, causing the metal to solidify and form billets. At present, the cooling method used by most crystallizers is relatively simple, mainly single cooling, which has certain limitations in efficiency. Under the single cooling method, the cooling water flows through the crystallizer for a short time, and the cooling effect is poor, resulting in insufficient heat transfer, which affects the solidification speed and quality of the metal. Secondly, due to the low cooling efficiency of the single cooling method, it is often necessary to increase the flow rate of cooling water or reduce the temperature of cooling water to meet production needs, which not only increases energy consumption, but may also cause certain damage to the equipment.

[0021] In this embodiment, when in use, liquid metal is injected into the crystallization inner cylinder 33, the water inlet interface 1 21 and the water inlet interface 23 are connected to the cooling water source, and the liquid metal begins to crystallize in the crystallization inner cylinder 33. Since the crystallization inner cylinder 33 and the cooling outer cylinder 31 are both made of copper, they have good thermal conductivity. When the liquid metal begins to crystallize, the heat generated will be quickly transferred to the cooling outer cylinder 31.

[0025] The cooling crystallization device of this embodiment realizes efficient crystallization of liquid metal through the design of double-layer cooling structure, improves production efficiency, and ensures the quality of crystallized metal. In addition, the crystallization inner cylinder 33 and the cooling outer cylinder 31 made of copper material not only have good thermal conductivity, but also have high corrosion resistance and wear resistance, which prolongs the service life of the equipment.

[0026] like Figure 1 As shown, there are multiple cooling crystallization shells 1, and each cooling crystallization shell 1 is respectively provided with an outer clamping strip 12 and a clamping groove 13 relative to the outer wall, the outer clamping strip 12 cooperates with the clamping groove 13, and the flow openings 11 between the multiple cooling crystallization shells 1 are sealed and connected by a seal.

The flow ports 11 between the multiple cooling crystallization shells 1 are connected to meet the cooling and cooling of batch liquid metal, and the temperature of the liquid metal can be controlled quickly and efficiently.
