Description

Technical Field

[0001] The utility model relates to the technical field of steel smelting, in particular to an energy-saving device utilizing sensible heat of continuous casting billets. Background Art

[0002] Continuously cast billets are products obtained by casting molten steel from a steelmaking furnace through a continuous casting machine. They are mainly divided into the following types based on their appearance: slabs, square billets, rectangular billets, and round billets. Round billets are mainly divided into tube billets and forging billets according to their diameter. Billets below 300 mm are mainly tube billets, which are generally used as raw materials for seamless steel pipes, and billets above 300 mm are mostly forging billets, which are generally used as raw materials for various forgings.

[0003] For example, a continuous casting billet sensible heat energy recovery and utilization device with the authorization announcement number "CN215638935U" has a heat collection pipe assembly that sucks external cold air into the casting mold, which can cool the mold and accelerate the cooling rate of molten steel. In addition, the impeller set in the heat exchange box can stir the water inside it, so that the cold and hot water inside are evenly mixed, which accelerates the water heating rate. However, in the continuous casting billet sensible heat energy recovery and utilization device, the heat collection pipe sucks external cold air into it through the first air inlet and the second air inlet to cool the casting mold. Due to the high temperature of the external air, it takes a long time to cool the casting mold, and it takes a long time to take out the cast workpiece and continue the casting work, thereby reducing the casting work efficiency. At the same time, the continuous casting billet sensible heat energy recovery and utilization device uses a motor to drive the impeller to cool the water. Since the position of the impeller is fixed, it takes a long time for the water to reach the required temperature, resulting in a large amount of recovered heat loss, so that the water heated by the recovered heat is less, thereby causing heat waste and failing to achieve the purpose of energy saving. Utility Model Content

[0030] Working principle:

[0031] When adjusting the water temperature using the continuous casting billet sensible heat energy saving device:

[0032] Casting mold cooling process:

[0033] The power supply of the first motor 302 is started, and the output shaft of the first motor 302 rotates to drive the roller 303 to rotate, thereby driving the slide bar 304 to slide back and forth along the surface of the fixed column 308, and at the same time, the protruding part of the slide bar 304 slides along the slide groove processed on the bent rod 305, so that the bent rod 305 swings back and forth, and the swinging back and forth of the bent rod 305 drives the sleeve 306 to slide along the surface of the bent rod 305, and the sleeve 306 moves back and forth to drive the vertical rod 307 to slide back and forth along the through hole processed on the first shell 301, and the back and forth movement of the vertical rod 307 drives the air conditioner 2 to move back and forth, and the external power supply of the air conditioner 2 is started, and the air conditioner 2 generates cold air, so that there is more cold air near the casting mold 15, and the exhaust fan 6 is started. The heat collecting tube 4 draws external cold air into the interior through two air inlets. Since the outer wall of the heat collecting tube 4 is in close contact with the casting mold 15, the cold air can quickly cool the casting mold 15, and the continuous casting billet can be quickly taken out to perform further casting work, thereby improving work efficiency.

[0034] Water temperature adjustment process:

[0035] A proper amount of cold water is added to the box 12 through the water inlet 9, and the exhaust fan 6 inputs the air heated by the casting mold 15 into the heat pipe 14 through the air pipe 5. The air heated by the casting mold 15 exchanges heat with the cold water through the outer wall of the heat pipe 14, so that the cold water in the box 12 is heated, and then the power supply of the second motor 702 is started. The second motor 702 is a servo motor. The output shaft of the second motor 702 drives the gear 703 to rotate back and forth through forward and reverse rotation, thereby driving the rack 704 to slide back and forth along the surface of the protruding part of the inner wall of the second shell 701. At the same time, the protruding part of the rack 704 slides back and forth along the slide groove processed on the swing rod 705, so that the swing rod 705 swings, and the swing of the swing rod 705 drives the moving block 706 to slide back and forth along the surface of the fixed plate 707;

[0036] At the same time, the moving block 706 slides back and forth along the slide groove processed on the second shell 701. The moving block 706 moves back and forth, driving the motor box 13 to move back and forth, thereby driving the stirring roller 10 to move back and forth, starting the power supply of the third motor 8, and the output shaft of the third motor 8 rotates to drive the stirring roller 10 to rotate, so as to quickly mix the uneven hot and cold water in the upper and lower parts of the box 12 to make the water temperature consistent, and observe the water temperature change in real time through the external temperature display 14. When the water temperature reaches the requirement, the hot water can be released through the water outlet 11 for use, and then cold water is added again through the water inlet 9 to continue heating. Such a cycle can continuously heat the cold water, so as to maximize the recycling of the air heated by the casting mold 15, thereby achieving the purpose of energy saving.
