Description

Technical Field

[0001] This utility model relates to the field of water cooling technology for rolling mills, specifically a modular control device for a high-speed wire rod water cooling section. Background Technology

[0002] In the modern production of metal wire rods, rolling is a common processing method. After rolling, the wire rod needs to be cooled sufficiently. Traditional high-speed wire rod water cooling sections use centralized cooling control, which has the following problems: the cooling water flow rate depends on manual adjustment, the temperature fluctuation range reaches ±50℃, resulting in grain coarsening; uneven water cooling temperature can easily cause steel pile-up accidents; and it is impossible to dynamically switch the cooling mode according to the steel grade, which restricts the development of high-end products.

[0003] Current improvements to cooling equipment for hot-rolled metal wire mainly focus on controlling the volume and flow rate of water cooling. However, they cannot solve the problem of multi-area coordinated control or propose the concept of modular cooling, but lack a steel stacking early warning linkage mechanism, resulting in low cooling efficiency and poor cooling effect. In view of this, this case was developed through in-depth research on the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides an implementation scheme: In the modern high-speed wire rod rolling process, the traditional high-speed wire rod water cooling section adopts centralized cooling control, which has the following problems: the cooling water flow depends on manual adjustment, the temperature fluctuation range reaches ±50℃, resulting in grain coarsening; uneven water cooling temperature easily causes steel piling accidents; and it is impossible to dynamically switch the cooling mode according to the steel grade, which restricts the development of high-end products. However, it cannot solve the problem of multi-area collaborative control, or it proposes the concept of modular cooling, but lacks a steel piling early warning linkage mechanism, resulting in low cooling efficiency and poor cooling effect.

[0018] To address the issues of crude temperature control and high steel stacking risks associated with traditional water-cooled sections, according to the instruction manual appendix... Figure 1-3 It is known that this application discloses a modular control device for a high-speed wire water-cooled section, including a water-cooled section frame 1. The water-cooled section frame 1 is a rectangular frame structure. A water-cooled housing 2 is provided on the water-cooled section frame 1. An inlet 3 and an outlet 4 are respectively provided at both ends of the water-cooled housing 2. The water-cooled housing 2 is divided into several cooling zones from the inlet 3 to the outlet 4. The modular control device is designed to achieve a dual improvement in precise temperature control and production safety through the linkage mechanism of zoned collaborative cooling and tension feedback early warning. The water-cooled mill casing 2 is divided into several cooling zones along the rolling direction to form an independent temperature control unit. The sprayers 52 of each zone are connected in parallel with the water supply pipes 54 through the water distribution pipes 53. The cooling water output by the water pump 55 with adjustable flow rate is distributed to each cooling tank 51 through the water distribution pipes 53.

[0019] Each cooling zone is equipped with a cooling control module 5 and a pressure detection module 6. The cooling control module 5 includes a cooling tank 51. Several cooling tanks 51 are provided on the water-cooled housing 2. A sprayer 52 is provided in each cooling tank 51. A water distribution pipe 53 is connected to the sprayer 52. A water supply pipe 54 is connected to one side of the water distribution pipe 53. A water pump 55 is connected to the end of the water supply pipe 54. The pressure detection module 6 includes a guide roller 61, a guide rod 62 is installed on the guide roller 61, a guide frame 63 is provided on one side of the cooling tank 51, the guide rod 62 is inserted into the guide frame 63, a pressure detector 64 is provided on the guide rod 62, a guide spring is provided inside the guide frame 63 pressing on the pressure detector 64, and an alarm 65 is provided outside the cooling tank 51 and connected to the pressure detector 64.

[0020] When rolling different steel grades, the control system automatically switches the cooling mode according to preset parameters: carbon steel adopts a stepped cooling of "strong at the front and weak at the back", with water pressure of 0.6MPa at the inlet section and 0.3MPa at the outlet section, while alloy steel adopts a "uniform slow cooling" mode with water pressure of 0.4MPa±5% throughout the section. The cooling mode switching time is less than 3 seconds.

[0021] Each zone pressure detection module 6 monitors the changes in wire rod position information in real time. As the rolled wire rod passes under the guide roller 61, the guide roller 61 is limited by the wire rod tension, so that the guide rod 62 has an upward initial pressure that is given to the pressure detector 64. The guide rod 62 compresses the guide spring preload of 500N±50N, triggering the pressure detector 64, and thus the pressure detector 64 is subjected to initial pressure. Before steel piling occurs, the posture of the rolled wire rod fluctuates greatly, which will cause the pressure detector 64 to be subjected to abnormal force. The pressure detector 64 uses a C9C-500N force sensor. If the detection value exceeds the threshold for 2 consecutive seconds, the alarm 65 is activated and linked to the upstream zone sprayer 52 to reduce the water pressure by 30%, forming a buffer zone for steel piling risk.

[0022] As a preferred option, the cooling tank 51 is a rectangular cavity shell, which is matched with the quick-release connecting pipe at the top of the sprayer 52 and the sealing ring is made of fluororubber, so as to realize modular quick replacement.

[0023] As a preferred option, the guide roller 61 further forms a floating connection structure with the guide rod 62 through the bearing seats at both ends. The surface of the guide roller 61 is overlaid with a tungsten carbide wear-resistant layer with a thickness of 2mm. When subjected to high-speed friction of the wire, its radial runout is ≤0.1mm, ensuring that the tension detection accuracy error is <5%.

[0024] As a preferred option, the limiting block 66 at the end of the guide rod 62 forms a mechanical hard limit with the inner cavity of the guide frame 63. When the guide spring fails, the limiting block 66 contacts the top surface of the frame to prevent the rod from falling off, and at the same time triggers an emergency stop signal to avoid the guide roller 61 from going out of control and causing a breakage accident.

[0025] As a preferred option, the sprayer 52 further adopts a swirling atomizing nozzle, whose internal spiral flow channel causes the cooling water to generate centrifugal motion, and the diameter of the atomized water droplets is ≤200μm. Combined with the Teflon-coated water distribution pipes 53, the heat exchange efficiency is improved compared with the traditional direct injection structure under the same water pressure.

[0026] In summary, this modular control device for the water-cooled section of high-speed wire rod, through deep coupling of modular zone control and pressure feedback, automatically compensates the spray volume of each zone proportionally when there are sudden changes in rolling speed or steel grade switching. Adjacent cooling tanks 51 form a pressure balance zone through hydraulic linkage valves, eliminating the water hammer effect of traditional centralized control. The steel stacking early warning mechanism reduces the accident rate through a three-level response. Combined with the modular quick-change structure, it shortens the changeover time of the production line, providing a reliable guarantee for the flexible production of high-end wire rods of multiple varieties.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
