Description

Technical Field

[0001] This invention belongs to the field of quenching and cooling technology, and specifically relates to a plate quenching and cooling device and its quenching method. Background Technology

[0002] With societal development, the demand for hot-rolled steel in the steel market is continuously increasing, especially in key pillar sectors such as aerospace, military, and nuclear energy. However, advancements in global technology place higher demands on industrial standards and precision, and similarly impose more stringent requirements on the strength and toughness of materials. Faced with increasingly complex and variable service conditions and practical needs, there is an urgent need for materials to possess superior strength-toughness matching properties. To meet these demands and improve the post-rolling strength and toughness of steel plates, innovation in the cooling device after manufacturing is essential.

[0003] With the emergence of various high-strength and high-toughness steels, aging treatment after steel plate preparation is particularly important. Cracking and deformation of plates during quenching and cooling are easily overlooked. Rapid cooling during quenching will generate internal stress in the workpiece. When the stress reaches a certain level, the workpiece will twist, deform, or even crack. Traditional quenching equipment has low heat dissipation efficiency and requires a large amount of cooling water. Therefore, it is necessary to design a plate quenching and cooling device that adopts different cooling process schemes according to the plate material, the usage environment, and the applicable scope, thereby improving the yield. Summary of the Invention

Furthermore, the position and angle of the sheet metal immersed in the cooling water tank are changed by the combined action of a rotary motor and a lifting rope in the adjusting assembly. Through the cooling path and optimized cooling process, the sheet metal yield is effectively improved, achieving omnidirectional, multi-angle, and multi-process quenching and cooling of the sheet metal, ensuring the uniformity and speed of the post-rolling sheet metal cooling process.

[0022] 3. The plate quenching and cooling device provided by the present invention, through the cooperation of the adjusting component and the clamping component, reciprocates in the plate immersion.

[0039] like Figure 8 As shown, the collection assembly 4 includes a collection cover 41, an annular pipe 42, a universal arm 43, a magnetic base 44, and a return pipe 45.

[0040] The quenching method of the plate quenching and cooling device of the present invention includes the following steps:

[0041] S1. The sheet material is transported by the transport roller 6 to the pallet roller 304 that is flush with it. The clamping assembly 3 adjusts the position of the ball head 310 on the extension plate 308 and the clamping rod 309 according to the size of the sheet material to ensure that the four clamping rods 309 stably press the four corners of the sheet material.

[0042] S2. According to the plate quenching process, under the combined action of the rotary motor 24 and the suspension rope 28 in the adjusting component 2, the position and angle of the plate immersed in the cooling water tank 13 are changed.

[0043] S3. After determining the immersion position and angle of the plate, the plate is slowly slid into the cooling water tank 13 under the action of the first lead screw 21. If the plate is horizontally immersed, after the clamping component 3 fixes the plate, only the second lead screw 305 moves vertically downward.

[0044] S4. The water pump 12 operates, and the cooling water in the water storage tank 11 is input into the cooling water tank 13 through the water inlet pipe 17. The water inside the cooling water tank 13 circulates rapidly. The water vapor generated during the cooling of the plate is collected by the collection hood 41 of the collection component 4. The position of the collection hood 41 can be adjusted by the universal arm 43, and it enters the water storage tank 11 through the annular pipe 42 and the return pipe 45.

[0045] S5. After the quenching process is completed, the plate is driven by the first lead screw 21 to rise to the same level as the transport roller 6, and the clamping rod 309 on the clamping assembly 3 is released, and the plate is then sent to another place via the transport roller 6.

[0046] The plate quenching and cooling device and quenching method of the present invention will be further described below with reference to embodiments:

[0047] The cooling water tank 13 is pre-filled with 1 / 2 cooling water by the water pump 12. After the plate comes out of the rolling mill, it is transported by the transport roller 6 to the pallet roller 304, which is flush with it. The clamping assembly 3 adjusts the position of the ball head 310 on the extension plate 308 and the clamping rod 309 according to the size of the plate to ensure that the four clamping rods 309 stably press the four corners of the plate. According to the specific quenching process, the position and angle of the plate immersed in the cooling water tank 13 are changed by the cooperation of the rotary motor 24 and the lifting rope 28 in the adjusting assembly 2.

[0048] After determining the immersion position and angle of the plate, the plate is slowly slid into the cooling water tank 13 under the action of the first lead screw 21. If the plate is immersed horizontally, after the clamping component 3 fixes the plate, only the second lead screw 305 moves vertically downwards, without considering the cooperation of the rotary motor 24 and the lifting rope 28. At this time, the water pump 12 works simultaneously. The remaining cooling water in the storage tank 11 is introduced into the cooling water tank 13 through the inlet of the cooling water tank 13 via the four water inlet pipes 17. At this time, the outlet valve 15 on the drain pipe 18 connected to the storage tank 11 is in the closed state. At the same time as water is introduced, the fan 19 in the cooling water tank 13 starts. With the slow water intake through the four inlets and the drive of the fan 19 at the bottom of the cooling water tank 13, the water inside the cooling water tank 13 flows rapidly, which can effectively remove the gas film generated on the surface of the plate during the quenching process.

[0049] After quenching, the sheet metal is lifted by the first lead screw 21 to be flush with the transport roller 6, releasing the clamping rod 309 on the clamping assembly 3, and then the sheet metal is sent elsewhere via the transport roller 6. The water temperature in the cooling water tank 13 is affected by the sheet metal quenching, causing it to rise and affecting the next quenching process. At this time, the outlet valve 15 opens. Water in the cooling water tank 13 flows into the storage tank 11 through the drain pipe. During the flow, the water passes through the return water tank 14 installed on the drain pipe 18. The return water tank 14 rapidly cools the return water in the drain pipe 18. After the water in the cooling water tank 13 flows back to the storage tank 11, the outlet valve 15 is closed. During the sheet metal quenching process, the water vapor generated in the cooling water tank 13 rises and is stored in the annular pipe 42 of the collection hood 41, then flows back to the storage tank 11 through the return pipe 45. At this point, quenching is complete, and the above steps are repeated for the next operation with a sheet metal of excellent performance. The slag generated during the plate quenching process settles at the bottom of the cooling water tank 13. After quenching, the plug 111 of the slag discharge port 110 at the bottom of the cooling water tank 13 is removed, allowing the impurities to flow out under the influence of the water remaining at the bottom of the cooling water tank 13.

[0050] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
