Description

Technical Field

[0001] This utility model relates to the field of hot-rolled bar technology, specifically a dual-channel controlled-cooling hot-rolled bar equipment. Background Technology

[0002] Currently, the conventional production process for wire rods is as follows: after molten steel passes through the intermediate ladle, crystallizer, and spray section of the continuous casting machine, it is cooled and solidified, and then straightened by a straightening machine to pull out the billet. The billet is then cut into fixed lengths by a flame cutting machine and sent to the continuous casting billet discharge area by a conveyor roller.

[0003] The existing Chinese utility model patent with publication number CN209520198U discloses a continuous casting and rolling production line for wire rods, including a continuous casting machine, a roller conveyor system, a temperature compensation system, and a wire rod rolling system. This production line can rapidly and concurrently transfer the billets produced by a multi-strand continuous casting machine to the wire rod rolling system. It employs a small-footprint induction heating device to compensate for online temperature loss and head-to-tail temperature differences in the billets. By combining the concurrent roller conveyor with the temperature compensation system, it can reduce and eliminate transverse and longitudinal temperature differences in the billets while lowering energy consumption and production costs, thus improving the performance of wire rod products and increasing the direct rolling rate when producing products of different specifications. The continuous casting and rolling production line can expand to produce high-quality carbon structural steel, alloy steel, and other special steels. It boasts high energy efficiency, is energy-saving and environmentally friendly, and ensures the quality of the wire rod products.

[0004] The existing hot-rolling bar equipment mostly uses a single-channel device to spray the bar for cooling. However, it is not convenient to control the spray volume during use, which makes it difficult to control the cooling of the bar and thus affects the processing effect of the bar.

[0029] Specifically, the top plate 15 is supported by two side plates 14, the bar is conveyed by the conveying roller 13, the cooling water is collected by the water storage tank 1, and the water is cooled by the operation of the cooling device 11 through the cold water pipe 12.

[0030] Two support frames 2 are fixedly installed on the top two sides of the water storage tank 1. The support frames 2 are in the shape of "U". A lifting rod 21 is fixedly installed inside the support frame 2. A detection plate 22 is fixedly installed at the bottom of the lifting rod 21. A temperature detection head 23 is fixedly installed at the bottom of the detection plate 22.

[0031] Specifically, the lifting rod 21 is supported by the support frame 2. The height of the detection plate 22 can be adjusted by raising and lowering the lifting rod 21. The temperature of the bar can be detected by the temperature detection head 23 at the bottom of the detection plate 22.

[0032] A water pump 3 is fixedly installed on one side of the water storage tank 1. A water delivery block 31 is fixedly installed on one side of the water pump 3.

A water outlet block 34 is fixedly installed on one side of the water outlet rod 33. A high-pressure nozzle 35 is fixedly installed at the bottom of the water outlet block 34.

[0033] Specifically, the operation of the water pump 3 can draw water out and send it into the interior of the water outlet plate 32 through the water delivery block 31. The water can be sent into the interior of the water outlet block 34 through the water outlet rod 33. The water can be sprayed out through the high-pressure nozzle 35, thereby achieving the effect of cooling control.

[0034] A liquid pump 4 is fixedly installed on the other side of the water storage tank 1. A conveying block 41 is fixedly installed on one side of the liquid pump 4. A water conveying plate 42 is fixedly installed on one side of the conveying block 41. A water outlet column 43 is fixedly installed on one side of the water conveying plate 42. A connecting pipe 44 is fixedly installed at the bottom of the water outlet column 43. A high-pressure nozzle 45 is fixedly installed at the bottom of the connecting pipe 44.

[0035] Specifically, the operation of the pump 4 can extract water and send it into the interior of the water conveying plate 42 through the conveying block 41.

The outlet block 34 on one side of the outlet rod 33 sends the water into the high-pressure nozzle 35. Finally, the high-pressure nozzle 35 sprays water onto the bar for controlled cooling, improving the practicality of the dual-channel controlled-cooling bar hot-rolling equipment. The pump 4 draws water from the storage tank 1 and sends it into the water delivery plate 42 via the conveyor block 41. The water delivery plate 42 then sends the water into the connecting pipe 44 via the outlet column 43. Water is fed into the high-pressure nozzle 45 through the connecting pipe 44 and sprayed out, thereby enabling controlled cooling of the bar stock. This improves the practicality of the dual-channel controlled cooling bar stock hot-rolling equipment. The water spray volume of the high-pressure nozzle 35 and high-pressure spray head 45 can be adjusted by regulating the power of the liquid pump 4 and the water pump 3. The high-pressure nozzle 35 and high-pressure spray head 45 are spaced apart, thus avoiding uneven water spray when the liquid pump 4 or the water pump 3 is turned off, further improving the practicality of the dual-channel controlled cooling bar stock hot-rolling equipment. The lifting rod 21 can be supported by the support frame 2. The height of the detection plate 22 can be adjusted by the movement of the lifting rod 21. The temperature can be detected by the temperature detection head 23 at the bottom of the detection plate 22, thereby adjusting the water output and the number of nozzles according to the temperature, improving the adjustability and practicality of the dual-channel controlled cooling bar stock hot-rolling equipment.
