Description

Technical Field

[0001] The present invention relates to the technical field of steelmaking continuous casting, and specifically relates to a cooling system for a steelmaking continuous casting machine. Background Technique

[0002] The production process of continuously casting high-temperature molten steel into billets with a certain cross-sectional shape and certain dimensional specifications is called continuous steel casting, and the equipment required to complete this process is called a continuous casting complete set of equipment. Among them, during the steel casting process, a cooling system is required to quickly exchange heat with the molten steel to cool it into a formed shape;

[0003] However, when the existing continuous casting machine cooling system is in use, the cooling effect is poor, the molten steel cannot be cooled evenly, which affects the cooling and forming effect. At the same time, during cooling, a large amount of water is required. If it is not recycled and is directly discharged, it will cause waste of resources. Therefore, in view of these situations, in order to avoid the above technical problems, it is indeed necessary to provide a cooling system for a steelmaking continuous casting machine to overcome the defects in the prior art. Summary of the Invention

[0004] The present invention provides a cooling system for a steelmaking continuous casting machine, which can effectively solve the problems of poor cooling effect, inability to evenly cool the molten steel, affecting the cooling and forming effect, and at the same time, during cooling, a large amount of water is required, not recycled, and direct discharge will cause waste of resources as mentioned in the above background technique.

[0005] To achieve the above object, the present invention provides the following technical solution: A cooling system for a steelmaking continuous casting machine, including a support base. At the middle position of the top end of the support base, there are symmetrically connected casting mold bases through bolts. At the top end of the casting mold bases, there are symmetrically snap-connected steel pouring channels. At the position on the other side of the casting mold bases corresponding to the top end of the support base, there is a conveying frame connected through bolts. At the positions on both sides of the casting mold bases corresponding to the top end of the support base, there is a secondary cooling and recycling mechanism. Start the first water pump, pump the water inside the cold water tank through the water extraction pipe, and use the cooperation of the three-way pipe and the splicing pipe to evenly transport it into the two horizontal pipes on one side of the casting mold base, so that the water accumulates inside the horizontal pipes, pushing the sealing ball to move, so that the sealing ball releases the seal on the inner cylinder, facilitating the water to evenly flow through the heat exchange boxes above and below the casting mold base through the heat exchange pipes, carrying the heat inside the heat exchange boxes, facilitating the rapid transfer of the heat inside the subsequent casting mold base to the inside of the heat exchange boxes, and improving the heat exchange efficiency;

[0006] One end of the casting embryo mold base is provided with a sealing and demolding conveying mechanism. When the electric telescopic rod is started, the sealing plate and the anti-deviation rod are pulled to slide obliquely upward along the limiting carriage, and the skateboard is driven to slide upward inside the vertical frame along the limiting rod, forcing both the skateboard and the sealing plate to move above the vertical frame and the limiting carriage, releasing the seal of the casting embryo mold base, facilitating the hydraulic rod to pull the traction plate, the push rod and the push plate to move, and ejecting the steel embryo from the casting embryo mold base, improving the convenience of demolding.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: The structure of the present invention is scientific and reasonable, and it is safe and convenient to use:

[0008] 1. A secondary cooling and circulation mechanism is provided. Through the cooperation of the first water pump, the water suction pipe, the three-way pipe and the splicing pipe, water is evenly conveyed into the two horizontal pipes on one side of the casting embryo mold base, causing water to accumulate inside the horizontal pipes, pushing the sealing ball to move, releasing the seal of the inner cylinder, facilitating water to evenly flow through the heat exchange boxes above and below the casting embryo mold base through the heat exchange pipes, taking away the heat inside the heat exchange boxes, improving the heat exchange efficiency, enabling the molten steel inside the casting embryo mold base to be quickly cooled, and at the same time making the heat dissipation on the upper and lower surfaces of the molten steel inside the casting embryo mold base more uniform;

[0009] The heat-exchanged water is sent into the two horizontal pipes on the other side of the casting embryo mold base through the heat exchange pipes, and then through the cooperation of the four-way pipe, the splicing pipe and the connecting pipe, the water is sent into the heat dissipation pipeline inside the air inlet channel. At the same time, the fan is started to generate suction, enabling the outside air to enter the air inlet channel and cool the water inside the heat dissipation pipeline. After the temperature of the water is reduced, the cooled water is sent back to the cold water tank through the return pipe, facilitating cyclic heat exchange and ensuring the production efficiency of steel casting;

[0010] Through the cooperation of the second water pump, the water outlet pipe and the shunt pipe, water is then evenly sent into the spray pipe and sprayed out through the high-pressure nozzles to perform secondary spray cooling on the conveyed steel embryo, further improving the forming effect of the steel embryo. The water sprayed down passes through the drainage groove and is centrally collected by the water storage tank, and then through the cooperation of the second water pump, the drain pipe and the four-way pipe, the water inside the water storage tank is sent into the connecting pipe, facilitating subsequent entry into the heat dissipation pipeline, reducing cooling recovery and facilitating cyclic use;

[0011] The steam is gathered through the spray channel, and due to the rising of the steam, the exhaust fan inside the exhaust cylinder is driven to rotate, generating suction, forcing the steam to gather inside the exhaust cylinder, and then the steam is sent into the water storage tank through the exhaust pipe, facilitating the liquefaction of the steam inside the water storage tank, improving the recycling and cyclic effect of water resources, reducing waste, and at the same time preventing the steam from spreading and scalding the surrounding staff.

[0012] 2. A sealing and demolding conveying mechanism is provided. The electric telescopic rod is used to pull the sealing plate to move, and with the cooperation of the anti-deviation rod, the sealing plate is limited in position, so that the sealing plate and the anti-deviation rod slide obliquely upward along the limiting slide frame, and drive the sliding plate to slide upward along the limiting rod inside the vertical frame, forcing the sliding plate and the sealing plate to move above the vertical frame and the limiting slide frame, releasing the seal of the casting embryo mold base. Then, the hydraulic rod is used to pull the traction plate, the push rod and the push plate to move, and the steel embryo is ejected from the casting embryo mold base, improving the convenience of demolding.

[0013] Due to the telescopic property of the support spring, the concave plate and the pressure roller are pushed down, so that the pressure roller cooperates with the conveying roller to clamp the ejected steel embryo. Then, the rotating motor is started, and the power is transmitted through the transmission gear, so that the two rotating rods rotate synchronously. Then, with the cooperation of the bevel gears, the transmission rod and the conveying roller are pushed to rotate, further conveying the steel embryo, so that the steel embryo is completely separated from the inside of the casting embryo mold base, facilitating subsequent processing.

[0014] In summary, through the cooperation of the secondary cooling and circulation mechanism and the sealing and demolding conveying mechanism, the heat exchange efficiency is improved, so that the molten steel can be quickly cooled and formed during the production process. Then, the formed steel embryo is demolded and conveyed, and during the conveying process, the steel embryo is secondarily sprayed and cooled, further improving the forming effect. At the same time, during the cooling process, the water resources can be recycled, improving the utilization rate of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Working principle and usage process of the present invention: First, molten steel is fed into the inside of the billet mold base 2 through the steel pouring channel 3, so that the molten steel fills the inside of the billet mold base 2. Then, the first water pump 504 is started to extract the water inside the cold water tank 502 through the water suction pipe 503, and through the cooperation of the three-way pipe 534 and the splicing pipe 519, it is evenly conveyed into the two horizontal pipes 514 on one side of the billet mold base 2, causing the water to accumulate inside the horizontal pipes 514, forcing the water pressure to increase, and then pushing the sealing ball 518 to move, releasing the seal on the inner cylinder 515, facilitating the water to flow evenly through the heat exchange pipes 513 above and below the billet mold base 2 in the heat exchange boxes 512, taking away the heat inside the heat exchange boxes 512, facilitating the rapid transfer of the heat exchange inside the billet mold base 2 to the inside of the heat exchange boxes 512, improving the heat exchange efficiency, rapidly cooling the molten steel inside the billet mold base 2, and at the same time making the heat dissipation on the upper and lower surfaces of the molten steel inside the billet mold base 2 more uniform;

[0044] Next, the heat-exchanged water flows into the two horizontal pipes 514 on the other side of the billet mold base 2 through the heat exchange pipes 513, and then through the cooperation of the four-way pipe 511 and the splicing pipe 519, the heat-exchanged water is sent into the connecting pipe 510, and through the connecting pipe 510, it is sent into the heat dissipation pipe 507 inside the air inlet channel 506. At the same time, the fan 508 is started to generate suction, so that the outside air enters the air inlet channel 506 to cool the water inside the heat dissipation pipe 507. After reducing the temperature of the water, the cooled water is sent back to the cold water tank 502 through the return pipe 509, facilitating cyclic heat exchange and ensuring the production efficiency of steel casting;

[0045] Next, when the molten steel inside the billet mold base 2 cools and solidifies into a steel billet, the electric telescopic rod 609 is started to pull the sealing plate 610 to move. At the same time, through the cooperation of the anti-deviation rod 611, the sealing plate 610 is limited, so that the sealing plate 610 and the anti-deviation rod 611 slide obliquely upward along the limit sliding frame 605, and synchronously drive the sliding plate 608 to slide upward along the limit rod 607 inside the vertical frame 606, forcing the sliding plate 608 and the sealing plate 610 to both move above the vertical frame 606 and the limit sliding frame 605, releasing the seal of the billet mold base 2. Then, the hydraulic rod 604 is started to pull the traction plate 603 to move, so that the traction plate 603 drives the push rod 601 and the push plate 602 to move, and the steel billet is pushed out of the billet mold base 2, improving the convenience of demolding;

[0046] Next, the ejected billet moves onto the conveyor rack 4. Due to the telescopic property of the support spring 616, the concave plate 614 and the pressure roller 615 are pushed down, causing the pressure roller 615 to cooperate with the conveyor roller 619 to clamp the billet. Then, the rotation motor 623 is started, and power is transmitted through the transmission gear 617, causing the two rotating rods 621 to rotate synchronously. Through the cooperation of the bevel gears 622, the transmission rod 618 and the conveyor roller 619 are pushed to rotate, further conveying the billet and enabling the billet to completely separate from the inside of the casting mold base 2, facilitating subsequent processing.

[0047] Then, the electric telescopic rod 609 extends and retracts to push the sealing plate 610 to slide down along the limit carriage 605, and the slide plate 608 is also lowered together, forcing the sealing plate 610 to fit and seal with one end of the casting mold base 2 again. At the same time, the hydraulic rod 604 pushes the traction plate 603, the push rod 601, and the push plate 602 to reset, facilitating the subsequent re-injection of molten steel into the casting mold base 2 for continuous steel casting.

[0048] Next, the second water pump 526 is started. Through the cooperation of the water outlet pipe 525, the water inside the cold water tank 502 is sent into the shunt pipe 522, then evenly enters the spray pipe 523, and is evenly sprayed out through the high-pressure nozzles 524 to perform secondary spray cooling on the conveyed billet, further improving the forming effect of the billet. The sprayed water then passes through the drain trough 531 and is centrally collected by the water storage tank 532. During the collection process, iron filings in the water are filtered through the filter screen. Then, through the cooperation of the second water pump 526, the drain pipe 533, and the four-way pipe 511, the water inside the water storage tank 532 is sent into the connecting pipe 510, facilitating subsequent entry into the heat dissipation pipeline 507 for reduced cooling recovery and convenient recycling.

[0049] Finally, during the spraying and cooling process, the generated steam is gathered inside the spray channel 520. As the steam rises, it pushes the exhaust fan 529 inside the exhaust pipe 527 to rotate, generating suction, improving the gathering effect, forcing the steam to gather inside the exhaust pipe 527, and then sending the steam into the water storage tank 532 through the exhaust pipe 530, facilitating the liquefaction of the steam inside the water storage tank 532, improving the recovery and recycling effect of water resources, reducing waste, and at the same time preventing the steam from spreading and scalding the surrounding staff.

[0050] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
