Description

Technical Field

[0001] This utility model relates to the field of high-speed wire rod production, and in particular to a high-speed wire rod production system. Background Technology

[0002] High-strength wire rod is an important raw material for steel reinforcement in construction. After cold drawing and other processing, it can be made into steel bars of various specifications for use in concrete structures, improving the load-bearing capacity and seismic performance of concrete. After being rolled in a finished product rolling mill, high-strength wire rod generally enters a coiling machine, where it is coiled into a regular coil shape. Before entering the coiling machine, the wire rod passes through a water cooling device to cool it to a suitable coiling temperature. After being coiled by the coiling machine, the wire rod falls onto an air-cooled roller conveyor for uncoiling and cooling to control its structure and properties. Subsequently, it undergoes subsequent processes such as coiling and bundling to form finished wire rod.

[0003] In the prior art, as shown in the appendix Figure 1 As shown, along the direction of steel movement, the front of the finished product mill is sequentially equipped with a water cooling device, pinch rolls, and a wire feeder. The pinch rolls are located at the feed end of the wire feeder, close to it. Because the high-speed wire rod is rolled into small diameters, the large amount of water released by the water cooling device and the steam generated after efficient heat exchange will create water turbulence on the surface of the steel bar, causing reverse resistance. This causes the steel to pile up in the water tank, resulting in a reduction in the mechanical properties of the finished product. To avoid the problem of steel piling up, the steel is output from the finished product mill to the pinch rolls and is clamped by the pinch rolls before the water cooling device is turned on for cooling.

[0004] After adopting the above technical solution, since the pinch roll is set between the water cooling device and the wire drawing machine, in order to avoid steel piling, the water cooling device can only be turned on for cooling after the pinch roll is clamped. The steel between the pinch roll and the water cooling device cannot be cooled in time, which results in an uncooled section at the head of the steel. Since this uncooled section is not cooled in time after being output from the finished mill, the quality generally cannot meet the standards and needs to be manually trimmed and removed, resulting in a low yield. Utility Model Content

[0005] To address the technical problem of low yield caused by the presence of an uncooled section at the head of the high-speed wire rod in the prior art, this utility model provides a high-speed wire rod production system that can avoid leaving an uncooled section at the head of the high-speed wire rod, thereby improving the yield and production efficiency of the high-speed wire rod.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a high-speed wire rod production system, which, along the direction of steel movement, sequentially includes a finished product rolling mill, a water cooling device, and a wire drawing machine, and further includes: a high-speed wire rod conveying device, which is located at the discharge end of the finished product rolling mill and at the feed end of the water cooling device, and the high-speed wire rod conveying device and the water cooling device can work simultaneously; and a hot metal detector, which is located near the discharge end of the high-speed wire rod conveying device.

[0007] This invention enables the conveying of steel output from the finished rolling mill through a high-speed wire rod conveyor, enhancing the steel's traveling force, overcoming water cooling resistance, eliminating steel piling, and controlling the timely operation of the water cooling equipment with the help of a hot metal detector, so that the rolled steel can be water-cooled before entering the wire rod extruder, reducing the length of the uncooled section, and improving the yield and high-speed wire rod production efficiency.

[0008] Furthermore, at least two water cooling devices are provided, and multiple water cooling devices can operate collaboratively or independently. At least one of the water cooling devices is equipped with the high-speed wire conveying device at its rear.

[0009] This invention, by setting up multiple water-cooling devices, can control the number of water-cooling devices involved in cooling according to the diameter of the wire, ensuring the cooling effect and reducing the energy consumption of the system.

[0010] Furthermore, three water cooling devices are provided, arranged along the direction of steel movement. From back to front, the three water cooling devices are named Water Cooling Device 1, Water Cooling Device 2, and Water Cooling Device 3. Two high-speed wire rod conveying devices are provided, arranged from back to front as High-speed wire rod conveying device 1 and High-speed wire rod conveying device 2. High-speed wire rod conveying device 1 is located at the rear of Water Cooling Device 1, and High-speed wire rod conveying device 2 is located at the rear of Water Cooling Device 2. Both the discharge ends of High-speed wire rod conveying device 1 and High-speed wire rod conveying device 2 are equipped with hot metal detectors.

[0011] Furthermore, the high-speed wire conveying device employs a high-speed wire pinch roller device.

[0012] Furthermore, it also includes a front hot metal detector and a rear hot metal detector. The front hot metal detector is located at the rear of the finished product rolling mill, and the feed end of the wire drawing machine is equipped with a feeding conveying device. The rear hot metal detector is located at the rear end of the feeding conveying device.

[0013] This invention, by setting up front and rear hot metal detectors, enables the high-speed wire conveyor and the feeding conveyor to work in a timely manner, thereby improving the working efficiency of the system.

[0014] Furthermore, the feeding conveying device adopts a high-speed wire clamping roller device.

[0015] As can be seen from the above technical solutions, this utility model has the following advantages:

[0016] This invention provides a high-speed wire rod production system. The high-speed wire rod conveyor system enables the transport of steel output from the finished rolling mill, enhancing the steel's traveling force, overcoming water cooling resistance, eliminating steel piling, and controlling the timely operation of the water cooling equipment in conjunction with hot metal detectors. This ensures that all rolled steel is water-cooled before entering the wire drawing machine, reducing scrap from the uncooled section and improving yield and high-speed wire rod production efficiency. By setting up multiple water cooling devices, the number of devices participating in steel cooling can be controlled according to the wire diameter, ensuring cooling effect and reducing energy consumption. The installation of front and rear hot metal detectors ensures timely operation of the high-speed wire rod conveyor and the feeding conveyor, further improving the system's efficiency.

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] like Figure 2 As shown in the figure, this specific embodiment provides a high-speed wire rod production system, which includes, in sequence along the direction of steel movement, a finished product rolling mill 2, a water cooling device, and a wire drawing machine 10. It also includes a high-speed wire rod conveying device and a hot metal detector 4. Along the direction of steel movement, the high-speed wire rod conveying device is located at the discharge end of the finished product rolling mill 2 and at the feed end of the water cooling device. The high-speed wire rod conveying device and the water cooling device can operate simultaneously. The hot metal detector 4 is located near the discharge end of the high-speed wire rod conveying device. When the operator sees the signal prompt (audio-visual signal) emitted by the hot metal detector 4, they can control the operation of the water cooling device via remote control or other means. In this specific embodiment, to achieve automated operation of the system, the water cooling device, the high-speed wire rod conveying device, and the hot metal detector 4 are all electrically connected to the system's controller. When the controller receives the electrical signal emitted by the hot metal detector 4, it can control the water cooling device to operate. In this specific embodiment, the high-speed wire rod conveying device adopts a high-speed wire rod pinch roller device.

[0023] This specific embodiment uses a high-speed wire rod conveyor to transport the steel output from the finished rolling mill 2, enhancing the steel's traveling force, overcoming water cooling resistance, eliminating steel piling, and controlling the timely operation of the water cooling equipment with the cooperation of the hot metal detector 4, so that the rolled steel can be water-cooled before entering the wire rod mill 10. Compared with the prior art, which uses a pinch roller set at the feeding end of the wire rod mill 10 as the feeding power, this reduces the length of the uncooled section and improves the yield and high-speed wire rod production efficiency.

[0024] Since this system is applicable to the production of high-strength wire rods of different diameters, and the cooling time required for steel of different diameters varies, in this specific embodiment, at least two water-cooling devices are provided. Multiple water-cooling devices can operate collaboratively or independently. At least one water-cooling device has a high-strength wire rod conveying device at its rear. By providing multiple water-cooling devices, the number of devices participating in the cooling process can be controlled according to the wire diameter, ensuring cooling effectiveness and reducing the system's energy consumption. Figure 2As shown in this specific embodiment, three water cooling devices are provided, arranged along the direction of steel movement. From back to front, the three water cooling devices are water cooling device 1 (5), water cooling device 2 (11), and water cooling device 3 (7). Two high-speed wire rod conveying devices are provided, arranged from back to front as high-speed wire rod conveying device 1 (3) and high-speed wire rod conveying device 2 (6). High-speed wire rod conveying device 1 (3) is located at the rear of water cooling device 1 (5), and high-speed wire rod conveying device 2 (6) is located at the rear of water cooling device 2 (11). The discharge ends of both high-speed wire rod conveying device 1 (3) and high-speed wire rod conveying device 2 (6) are equipped with hot metal detectors 4. When producing finer wire rods, only water cooling device 5 can be used for cooling. Since finer wire rods are more prone to vibration during water cooling, wire rod conveyor 3 and wire rod conveyor 6 can be used simultaneously to improve the quality of finer diameter wire rods and reduce production energy consumption. When producing thicker wire rods, two or three water cooling devices (water cooling device 5 must be running) can be controlled to ensure cooling effect. When the wire rod is thicker, the vibration of the steel is not serious, and only wire rod conveyor 3 can be used for conveying to achieve the technical effect of reducing production energy consumption.

[0025] like Figure 2 As shown, to further improve the automation level of this system, this specific embodiment also includes a front hot metal detector 1 and a rear hot metal detector 8. The front hot metal detector 1 is located at the rear of the finished product rolling mill 2, and the feeding end of the wire feeder 10 is equipped with a feeding conveyor 9. The rear hot metal detector 8 is located at the rear end of the feeding conveyor 9. Both the front hot metal detector 1 and the rear hot metal detector 8 are electrically connected to the controller of this system. With this configuration, when the front hot metal detector 1 senses steel, it can control the finished product rolling mill 2 to work. After a delay of a set time t1 (set according to the rolling speed), it controls the high wire conveyor 3 to work to ensure timely delivery of steel. When the rear hot metal detector 8 senses steel, it can control the feeding conveyor 9 to work after a delay of a set time t2 (set according to the conveying speed and the distance between the feeding conveyor 9 and the rear hot metal detector 8) to ensure that the steel smoothly enters the wire feeder 10. In this specific embodiment, the feeding conveyor 9 adopts a high wire pinch roller device.

[0026] In this specific embodiment, the hot metal detector 4, the front hot metal detector 1, the rear hot metal detector 8, the high wire feeding roller device, and the water cooling equipment are all products purchased from the market. For example, the hot metal detector 4, the front hot metal detector 1, and the rear hot metal detector 8 can be infrared thermometers, which are existing technologies, and their structures will not be described in detail in this article.

[0027] The working process of this system is as follows:

[0028] Once the hot metal detector 1 detects steel, the finished product rolling mill 2 immediately starts rolling the steel. After a set delay time t1, the high-speed wire rod conveyor 3 starts working, clamps the steel, and conveys it towards the water cooling equipment 5. When the hot metal detector 4 detects steel at the discharge end of the high-speed wire rod conveyor 3, it immediately controls the water cooling equipment 5 to start ahead of time to ensure that the length of the uncooled section is zero. The steel moves continuously in the water cooling equipment 5 under the action of the high-speed wire rod conveyor 3.

[0029] When the steel diameter is small, such as φ6mm or φ8mm, the high wire rod conveyor 26 starts working after the hot metal detector 4 at the discharge end of the high wire rod conveyor 26 senses the steel. The water cooling equipment 211 and the water cooling equipment 37 do not work. After the hot metal detector 8 senses the steel, the feeding conveyor 9 starts working after a set delay of t2. This realizes the full-process conveying of steel with smaller diameters and avoids water cooling vibration, which affects product quality.

[0030] When the steel has a large diameter such as φ10mm or φ12mm, after the hot metal detector 4 on the outlet side of the high wire rod conveyor 26 senses the steel, the water cooling equipment 211 and the water cooling equipment 37 start working simultaneously, and the high wire rod conveyor 26 does not work. After the hot metal detector 8 senses the steel, the feeding conveyor 9 starts working after a set delay of t2.

[0031] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0032] 1. The high-speed wire rod conveyor can convey the steel output from the finished rolling mill 2, enhance the steel's traveling force, overcome water cooling resistance, eliminate steel piling, and control the water cooling equipment to work in a timely manner with the help of the hot metal detector 4, so that the rolled steel can be water cooled before entering the wire drawing machine 10, reducing the length of scrap in the uncooled section, and improving the yield and high-speed wire rod production efficiency.

[0033] 2. By setting up multiple water cooling devices, the number of water cooling devices participating in the cooling of steel can be controlled according to the diameter of the wire, ensuring the cooling effect and reducing the energy consumption of the system.

[0034] 3. By setting up front hot metal detector 1 and rear hot metal detector 8, the high wire conveyor 3 and feeding conveyor 9 can work in a timely manner, thereby improving the working efficiency of the system.
