Description

Technical Field

[0001] This utility model relates to the field of continuous casting technology, specifically a cooling spray device for continuous casting. Background Technology

[0002] Continuous casting is the core process for continuous steel production in the steel industry. Continuous casting technology replaces traditional ingot casting by directly pouring molten steel into solid billets, offering advantages such as high metal yield, low energy consumption, and high production efficiency. The common process flow mainly includes a ladle, tundish, crystallizer, secondary cooling zone, straightening machine, and cutting machine. In the secondary cooling zone, a spray system is required to cool the billet.

[0003] The existing secondary cooling spray devices in the secondary cooling zone of the continuous casting process are mostly in the form of spray water strips and nozzles. When in use, the spray is arranged along the direction of billet pulling to fully cool the billet in the secondary cooling process, so as to achieve the purpose of high quality and high output solidification of continuous casting billets.

[0004] When cooling the billet, water mist nozzles are usually used to spray water onto the billet for cooling. However, when water comes into contact with the high-temperature billet, a large amount of water vapor is generated. This water vapor is extremely hot and can not only corrode other equipment but also cause harm to the human body. Utility Model Content

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] This embodiment provides, for example Figure 1-5 The cooling spray device for continuous casting shown includes a spray body 1 and an exhaust frame 2 connected to both sides of the spray body 1. The spray body 1 includes a main frame 101, with connecting support frames 102 fixed on both sides of the bottom end of the main frame 101, and an arc plate frame 103 fixed on the bottom surface of the main frame 101. An air inlet groove 104 is opened on the bottom surface of the arc plate frame 103, and an exhaust chamber 105 is connected to the top surface of the air inlet groove 104. A spray pipe 106 is laid in the center of the interior of the exhaust chamber 105, and branch pipes 107 are fixed on both sides of the spray pipe 106. A spray head 108 is fixed on the bottom surface of the branch pipe 107. An exhaust pipe 109 is fixed in the center of the top surface of the exhaust chamber 105, and a pressure gauge 111 is connected to one side of the top surface of the exhaust chamber 105. The inner wall of the exhaust pipe 109 is filled with a filter element 110.

[0022] Furthermore, the connecting support frame 102 is arranged and fixed along both sides of the bottom end of the main frame 101, and the bottom surface of the main frame 101 is fixed to the arc plate frame 103 in a semi-arc shape; the air inlet slot 104 and the spray head 108 are arranged alternately along the bottom surface of the arc plate frame 103, and the air inlet slot 104 and the exhaust pipe 109 are connected to the interior of the exhaust chamber 105; the exhaust pipe 109 is arranged equidistantly along the center line of the top surface of the exhaust chamber 105, and the central filter element 110 of the exhaust pipe 109 is a ceramic-based porous structure; the branch pipe 107 is arranged equidistantly along the bottom surface of the arc plate frame 103, and the branch pipe 107 is connected to the spray pipe 106 and the spray head 108.

[0023] like Figure 1-4 As shown, the cooling spray device in this embodiment is supported by the main frame 101 and the connecting support frames 102 distributed on both sides of the bottom. The arc plate frame 103 structure on the bottom surface of the main frame 101, together with the arc support, can reduce water stains and steam splashed during spraying, and play a certain protective role. Together with the internal exhaust chamber 105 and the top exhaust pipe 109, the steam is collected and discharged, which can not only limit and protect the steam, providing safety for the production environment, but also preheat the steam for utilization. At the same time, the exhaust pipe 109 is also provided with a ceramic-based porous filter core 110 inside, which can filter the steam in the high-temperature environment and improve the quality of steam preheating utilization. The spray pipe 106, through the arc-shaped branch pipes 107 on both sides and the spray head 108, sprays the continuously cast billet quickly and evenly to cool it down, improving the cooling efficiency.

[0024] like Figure 5 As shown, the drain frame 2 includes a side water pipe 201, the inner wall of which is connected to a side drain pipe 202, and a sealing ring 203 is fixed to one end of the side drain pipe 202. The inner wall of the sealing ring 203 is fixed to both sides of the main frame 101. One end of the side water pipe 201 is connected to a manifold 204, and a valve pipe 205 is fixed to one end of the manifold 204.

[0026] When the steam is temporarily stored in the exhaust chamber 105 of the cooling spray device in this embodiment, some of the steam will condense as the temperature drops. At this time, it can flow naturally to the bottom of both sides of the exhaust chamber 105 along the semi-circular structure of the bottom surface, and be discharged to the side water pipe 201 in conjunction with the side drain pipe 202, which further improves the safety of steam discharge and improves the utilization of liquid steam.

[0027] In summary, when using the cooling spray device in this embodiment, the main frame 101 of the device is first fixed to the top surface of the billet line of the continuous casting production line through the connecting support frames 102 on both sides of the bottom end. After it is stable, it can be put into cooling use. When the billet is transferred to the bottom of the device, cooling water can be input through the spray pipe 106 and discharged through the branch pipes 107 and spray heads 108 arranged on both sides to cool the billet passing below. High-temperature steam is then generated. The high-temperature steam rises and is discharged from the air inlet trough 104 into the exhaust chamber 105 for temporary storage, and is discharged through the exhaust pipe 109. After being processed by the filter element 110 in the exhaust pipe 109, the steam can be used for preheating. Some of the water generated by the cooling of the steam flows into the inside of the device and is discharged through the side drain pipe 202 to the side water pipe 201 for steam water collection, which can avoid water vapor accumulation affecting the use of the equipment.
