Description

Technical Field

[0001] This application relates to the field of hot-rolled strip steel production, and includes, but is not limited to, a hot-rolled strip steel production control method, apparatus, equipment, and storage medium. Background Technology

[0002] Laminar flow cooling of hot-rolled strip is an online controlled cooling process used after rolling for hot-rolled steel plates or strips. It accelerates the cooling of the metal material through laminar water flow. Its main device consists of a cooling zone formed by laminar flow manifolds above the finishing mill output roller table. It can be further divided into two forms: tube laminar flow and water curtain cooling. The former uses an inverted U-shaped siphon array to achieve high-density cooling, while the latter uses a narrow-slit manifold to form a curtain of water flow for synchronous cooling. At the finishing mill exit conveyor roller table, the strip head is arc-shaped. When the head thickness is thin or the strip type is mild steel, the head is prone to floating upwards or arching downwards into the roller table gaps, resulting in scrap steel and affecting strip stability and production smoothness. Summary of the Invention

[0003] In view of this, the hot-rolled strip steel production control method, apparatus, equipment, and storage medium provided in the embodiments of this application can control the transmission mechanism to accelerate transmission when preset conditions are triggered, thereby avoiding the immediate acceleration after steel biting, which would cause the thin strip steel head to arch and become scrap steel as it passes through the finishing mill exit roller table, thus making the production process safe and smooth.

[0018] The length of the strip within the transmission mechanism is determined in real time from the moment the transmission mechanism bites the strip.

[0019] When the strip length is the preset length, the preset condition is determined to be triggered.

[0020] In one possible implementation, the length of the strip within the conveying mechanism is determined in real time from the moment the conveying mechanism bites the strip, including:

[0021] The position detection sensor is activated at the moment the strip bites the conveyor to detect the position of the strip within the conveyor and obtain the strip length.

[0028] After the laminar flow cooling device's transmission mechanism bites the steel, it detects in real time whether the preset conditions have been triggered.

[0029] When preset conditions are triggered, the control transmission mechanism accelerates transmission.

[0031] The cooling module is used to control the laminar flow cooling device to cool the conveyed strip steel.

The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0055] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0056] It should be noted that the terms "first, second, third" used in the embodiments of this application are used to distinguish similar or different objects and do not represent a specific order of objects. It can be understood that "first, second, third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0057] The hot-rolled strip steel production control method of this application embodiment can be executed by any electronic device capable of controlling the hot-rolled strip steel system. This electronic device may include, but is not limited to, mobile phones, wearable devices (such as smartwatches, smart bracelets, smart glasses, etc.), tablet computers, laptops, vehicle terminals, PCs (Personal Computers), etc. The functions implemented by this method can be achieved by a processor in the electronic device calling program code. Of course, the program code can be stored in a computer storage medium. Therefore, the electronic device includes at least a processor and a storage medium.

[0058] The hot-rolled strip steel production control method of this application can be used in any application scenario of hot rolling process for producing thin steel. For example, the embodiments of this application can be applied to application scenarios of controlling the hot-rolled strip steel production process. Alternatively, it can also be applied to application scenarios of controlling the hot-rolled steel plate production process.

[0059] Hot-rolled strip steel is one of the most important products in the modern steel industry, widely used in automobiles, bridges, construction, pipelines, containers, and other fields. Its core process involves rolling steel billets thinner and processing them into coils above the recrystallization temperature. The hot-rolled strip steel process typically includes heating, rolling, cooling, and coiling. During the cooling process, if the strip head is thin or the steel type is mild, the head is prone to lifting upwards or arching downwards and inserting into the roller gap, resulting in scrap and affecting strip stability and production smoothness.

[0060] Therefore, the technical problem solved by the embodiments of this application is how to ensure the smooth progress of the hot-rolled strip steel production process and reduce the scrap rate of the hot-rolled strip steel production process.

[0061] The hot-rolled strip steel production control scheme of this application embodiment will be described in detail below with reference to the accompanying drawings.

[0062] Figure 1 A flowchart illustrating a hot-rolled strip steel production control method according to an embodiment of this application is shown. Figure 1As shown, the hot-rolled strip steel production control method of this application embodiment may include the following steps S10-S20.

[0063] For ease of description, the hot-rolled strip steel production control method of this application embodiment is described using an electronic device as the execution subject. It should be understood that the execution subject of this application embodiment can also be a processor or chip in an electronic device, and this application embodiment does not impose any limitations.

[0064] Step S10: Control the finishing rolling device to finish rolling the heated strip and then output it.

[0065] In one possible implementation, electronic equipment controls the hot-rolled strip steel system to produce strip steel. This system may include a heating unit, a roughing mill, a finishing mill, a laminar flow cooling unit, and a coiling unit. The heating unit takes rectangular steel billets (referred to as "slabs") produced by continuous casting as raw materials, cleans them, and feeds them into a walking beam furnace. The furnace heats the slabs to an austenitic temperature range of approximately 1200°C-1300°C, homogenizing their microstructure and imparting good plasticity, preparing them for subsequent rolling. The roughing mill feeds the red-hot slabs from the furnace into a high-pressure water descaling box to remove surface iron oxide scale. Then, through multiple passes of reciprocating rolling in the roughing mill, the thick slabs (e.g., 200-300 mm thick) are rolled into intermediate slabs approximately 30-50 mm thick. After roughing, the beginning and end portions of the intermediate slabs are often trimmed to ensure the quality of subsequent rolling.

[0066] Optionally, the intermediate billet output from the roughing mill enters the finishing mill via its conveyor rollers. Before entering the finishing mill, the hot-rolled strip system can descale the intermediate billet again to remove newly formed secondary iron oxide scale during conveying. The red-hot intermediate billet is then conveyed into a continuous rolling mill consisting of 6-7 finishing stands. Within the continuous rolling mill, the intermediate billet is rolled at high speed and continuously to the final required thickness (typically 1.2 mm-25 mm).

[0067] In some embodiments, the entire process described above can be executed by electronic devices controlling the various devices in the hot-rolled strip steel system. The strip steel output after being processed by the finishing rolling device is the required strip steel. However, the temperature of the output strip steel is too high to be directly coiled at this time, and it needs to be cooled by a laminar flow cooling device.

[0068] Step S20: Control the laminar flow cooling device to transport the strip output from the finishing mill to the coiling device.

[0069] In one possible implementation, the thin steel sheet (referred to as "strip") exiting the finishing mill is still at a very high temperature (approximately 800°C-900°C). Electronic equipment controls a laminar flow cooling device to cool the strip output from the finishing mill and further conveys the cooled strip to a coiling device to obtain a steel coil. The laminar flow cooling device includes a laminar flow cooling section extending for tens of meters, which includes a conveying mechanism for transporting the strip and a cooling mechanism for cooling the strip.

[0070] Optionally, the conveying mechanism in the laminar flow section includes multiple sets of outlet output rollers for forward conveying the strip steel entering the rollers. The cooling mechanism in the laminar flow section may include a dense water spray system arranged vertically for spraying water to cool the thin steel sheet conveyed by the conveying mechanism, achieving controllable rapid cooling. Each roller in the conveying mechanism rolls at a slower speed when not gripping the steel, and at a higher speed after gripping. The gripping state refers to the state in which the strip steel is clamped by the upper and lower rollers; the moment the conveying mechanism begins gripping is the moment the first set of rollers grips the steel. Related technologies that accelerate directly after the conveying mechanism grips the steel can easily cause the strip head to float upwards or arch downwards into the roller gaps when the head is thin or the steel type is mild steel, resulting in scrap steel and affecting strip steel stability and production smoothness.

[0071] In some embodiments, to reduce the probability of scrap steel being generated due to the strip head lifting upwards or arching downwards and inserting into the roller gap during cooling, the electronic equipment can pre-set a preset condition. After the conveying mechanism of the laminar flow cooling device bites the steel, the electronic equipment can detect in real time whether the preset condition has been triggered. If the preset condition is triggered, the electronic equipment controls the conveying mechanism to accelerate the conveying. If the preset condition is not triggered, the electronic equipment controls the conveying mechanism to roll at the initial speed of the unbiting state.

[0072] Based on the above technical features, the embodiments of this application can not start accelerating immediately after the transmission mechanism in the laminar flow cooling device bites the steel. Instead, by setting preset conditions, the acceleration is delayed for a period of time after the steel biting begins. This delayed acceleration allows the front end of the strip to be cooled and transmitted at a slow speed, preventing the strip head from floating upwards or arching downwards and inserting into the roller gap due to cooling.

[0073] In some embodiments, the preset condition set by the electronic device can be that acceleration will only occur after the transmission mechanism has engaged the steel for a preset duration. That is, the electronic device starts timing from the moment the transmission mechanism engages the steel, and determines that the preset condition has been triggered if the timing result is the preset duration. Optionally, the electronic device can start a timer at the moment the steel engagement is detected to time the engagement duration. The specific preset duration can be adjusted according to the production environment and product characteristics. This method allows the timer to be started only after the steel engagement, reducing the computational load on the electronic device and its overall energy consumption.

[0074] In other embodiments, the preset condition set by the electronic device can be that acceleration only occurs after the strip enters the conveying mechanism and reaches a preset length. That is, the electronic device determines the strip length within the conveying mechanism in real time from the moment the conveying mechanism bites the strip. If the strip length is the preset length, the preset condition is triggered. Optionally, the electronic device can activate a position detection sensor at the moment the conveying mechanism bites the strip to detect the strip position within the conveying mechanism and obtain the strip length. This position detector can be set inside the conveying mechanism at a preset length from the conveying mechanism entrance. The specific preset length can be adjusted according to the production site and product characteristics. This method allows the position detection sensor to be activated only after the strip has bitten the strip, reducing the computational load of the electronic device and the overall energy consumption of the equipment.

[0075] Optionally, when the electronic equipment determines that the preset conditions have been triggered, it can control the speed of the conveying mechanism to accelerate uniformly to the target speed with a preset acceleration. This uniform acceleration method can prevent the strip head from rising upwards or arching downwards and inserting into the roller table gap due to excessive acceleration.

[0076] Figure 2 A schematic diagram illustrating the speed of a transmission mechanism according to an embodiment of this application is shown. For example... Figure 2 As shown, in related technologies, the electronic equipment moves at a constant speed during the uniform speed stage of the roller conveyor before the steel is bitten. After the steel is bitten, the electronic equipment determines the bitten moment as the time point for the roller conveyor to accelerate. That is, the electronic equipment accelerates the speed of the output rollers at the exit of the finishing mill and the exit of the cold flow cooling zone based on the acquired steel bitten signal.

[0077] Figure 3 A schematic diagram illustrating the speed of a transmission mechanism according to an embodiment of this application is shown. Figure 3As shown in the embodiment of this application, the electronic device moves at a constant speed during the uniform speed stage of the roller conveyor before the conveyor mechanism bites the steel. After biting the steel, the electronic device determines the time point after the biting moment as the roller conveyor speed-up point by setting preset conditions, and then begins to accelerate. That is, the electronic device accelerates the speed of the roller conveyor at the roller conveyor speed-up point based on the acquired frame biting signal and performs preset condition judgment based on the signal. If the preset conditions are met, the electronic device accelerates the speed of the exit roller conveyor at the exit of the finishing mill and the exit roller conveyor in the cold flow cooling area.

[0078] Based on the above technical features, the embodiments of this application can not start accelerating immediately after the transmission mechanism in the laminar flow cooling device bites the steel. Instead, by setting preset conditions, the acceleration is delayed for a period of time after the steel biting begins. This delayed acceleration allows the front end of the strip to be cooled and transmitted at a slow speed, preventing the strip head from floating upwards or arching downwards and inserting into the roller gap due to cooling, thus avoiding scrap steel and making the production process safe and smooth.

[0079] It should be understood that although the steps in the above flowcharts are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the above flowcharts may include multiple sub-steps or multiple stages.
