[0030] The embodiment of the present application provides a strip steel edge quality control method, a device, an electronic device and a storage medium, and solves the technical problems of low strip steel edge quality and low service life of a rolling device in the process of rolling a strip steel in the prior art.
[0031] The technical solution provided by the embodiment of the present application is to solve the above technical problems, and the general idea is as follows:
[0032] By monitoring the actual distance between the head of the to-be-rolled slab and the rough rolling roller and based on the transmission speed of the to-be-rolled slab, the steel biting moment of the rough rolling roller can be determined. Further, the rough rolling roller lubricating device is controlled to operate within a preset time period before the steel biting moment, so as to lubricate the surface of the rough rolling roller in advance.
[0033] In order to better understand the above technical solution, the above technical solution will be described in detail in combination with the drawings of the specification and specific embodiments.
[0034] Firstly, it should be explained that the term "and / or" appearing in the present document is only to describe the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the existence of A alone, the existence of A and B together, and the existence of B alone. In addition, the character " / " in this document generally represents an "or" relationship between the front and rear associated objects.
[0035] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.
[0036] In a first aspect, an embodiment of the present application provides a strip steel edge quality control method, which can be applied to a rolling device, and the rolling device can include a rough rolling roller and a rough rolling roller lubricating device.
[0037] The rough rolling roller is used to roll a to-be-rolled slab into a rough rolling strip, and the rough rolling roller lubricating device is used to lubricate the rough rolling roller.
[0038] It can be understood that the above rolling device can include a hot rolling device and a cold rolling device; and the above rough rolling roller can be a rough rolling vertical roller.
[0039] The rough rolling vertical roller works without lubrication, and after the vertical roller surface contacts with process water, a high-hardness oxide scale layer is formed. The rough oxide scale layer can accelerate the wear speed of the vertical roller surface and shorten the online service life of the vertical roller. Meanwhile, the rough oxide scale layer on the vertical roller surface can also cause defects on the surface of the strip steel edge during the rolling process of the rough rolling vertical roller, which affects the product quality of the strip steel.
[0040] In order to reduce the influence of the rough rolling roller surface oxide skin layer on the strip steel edge quality, please see Figure 1 The strip steel edge quality control method provided by the embodiment of the present application can include the following steps S101-S102:
[0041] Step S101: monitoring the actual distance between the head of the to-be-rolled slab and the rough rolling roller, and determining the steel biting time of the rough rolling roller based on the transmission speed of the to-be-rolled slab.
[0042] Specifically, before the to-be-rolled slab enters the rough rolling roller, the actual distance between the head of the to-be-rolled slab and the rough rolling roller can be obtained by using a distance sensor, for example, a laser range finder. The transmission speed of the to-be-rolled slab can be obtained by using a tachometer, or indirectly through the rotational speed of the transmission roller.
[0043] In this way, based on the actual distance and the transmission speed, the time required for the head of the to-be-rolled slab to reach the rough rolling roller can be calculated, and the steel biting time of the rough rolling roller can be calculated.
[0044] Step S102: controlling the rough rolling roller lubricating device to operate within a preset time length before the steel biting time.
[0045] Specifically, the preset time length can be set according to the actual application scenario, for example, in the scenario where the rotational speed of the rough rolling roller is relatively slow, the preset time length can be set to be a little longer. In the specific implementation process, the preset time length can be set to 4-6 seconds, for example, 5 seconds.
[0046] In the specific implementation process, the comparison results of the surface quality of the rough rolling roller using the embodiment of the present application and the surface quality of the rough rolling roller using the prior art can be seen from Figure 2 and Figure 3 The surface of the rough rolling roller using the prior art is rougher, and the surface of the rough rolling roller using the embodiment of the present application is smoother.
[0047] After the rough rolling roller lubricating device operates, although the roller surface quality can be effectively improved, there are still the following problems: the rough rolling roller lubrication increases is beneficial to improve the roller surface quality, but it is easy to make the rough rolling roller slip.
[0048] In order to balance the roller surface quality and the rough rolling roller slip in the process of rough rolling roller lubrication, if it is necessary to optimize the rough rolling roller slip, the lubrication of the rough rolling roller can be controlled as follows:
[0049] The process water (cooling water) is set to be always on, and the water quantity is fixed. The odd lane of lubricating oil is opened, and when the rough rolling roller bites the steel, the odd lane of lubricating oil is opened; when the rough rolling roller throws the steel, the odd lane of lubricating oil is closed. The even lane of lubricating oil is not opened.
[0050] In the implementation process, the rolling device can further include a hammer head, specifically a sizing mill hammer head, which is arranged upstream of the rough rolling roller and used for beating the rough plate blank to change the shape of the rough plate blank. Since the hammer head is a major wear part, the selection of the material has a very important influence on its performance.
[0051] Since the temperature of the plate blank in contact with the sizing mill hammer head is as high as 1100-1200℃ in the working state, the hammer head is required to have good thermal cracking resistance, and at the same time, the hammer head is required to have sufficient hardness and toughness to resist fatigue spalling and prevent cracking.
[0052] In the component design of the hammer head material, a proper amount of carbon, silicon, manganese and some alloy elements are generally contained. Among them, carbon is the main factor affecting the performance of the material. Within a certain range, with the increase of the carbon content in the steel, the hardness and strength of the material increase, and the plasticity and toughness decrease; silicon plays a solid solution strengthening role in the steel, which can inhibit or delay the decomposition of carbides of supercooled austenite, improve the strength, hardness and toughness of the steel; manganese and iron form a solid solution to improve the strength and toughness of ferrite and austenite in the steel, and manganese can significantly delay high-temperature transformation under certain conditions, improve the bainite hardenability, and lower the bainite transformation temperature, thereby increasing the strength of the ferrite matrix.
[0053] The traditional hammer head material is generally selected from 16Mn medium-high manganese steel with relatively mature production process, but it is found in production practice that the thermal cracking resistance is poor and the hammer head is short in time on the machine. In order to solve the problem of poor thermal cracking resistance of the hammer head, as an optional implementation mode, the material of the hammer head can also be set as nodular cast iron, specifically, the matrix of the nodular cast iron is 85% or more pearlite, and the spheroidizing rate of the nodular cast iron after heat treatment is ≥85%.
[0054] After the hammer head made of traditional 16Mn material is used for 1 week, the surface quality of the hammer head after being taken off the machine is as shown in Figure 2 It can be seen that a large number of coarse linear cracks appear on the surface, and local chipping occurs. After the hammer head made of nodular cast iron material provided by the embodiment of the present application is used for 3 weeks, the surface quality of the hammer head after being taken off the machine is as shown in Figure 3 It can be seen that a large number of fine cracks appear on the surface of the hammer head, the surface material is complete, and no local chipping occurs.
[0055] Compared with the existing hammer head material, the hammer head material of the embodiment of the present application can reduce the chipping and cracking of the hammer head, improve the surface quality of the rough rolled strip steel, and prolong the time of the hammer head on the machine from 1 week to 3 weeks, and the on-machine cycle can be prolonged from the existing 250,000 tons to more than 300,000 tons.
[0056] In the implementation process, the rolling equipment can further include a finishing guide plate and a finishing mill, the finishing guide plate is arranged downstream of the rough rolling roller, and is used to guide the rough rolling strip into the finishing mill to obtain a finishing rolling strip.
[0057] The main function of the finishing guide plate is to center and guide, and the rough rolling strip is accurately centered in the rolling process by changing the position of the guide plate, so that the rough rolling strip is not deviated or warped, thereby improving the stability in the rolling process.
[0058] The conventional finishing guide plate wear-resistant lining plate is made of ordinary carbon manganese steel, and the lining plate is seriously worn when the machine is taken out, the wear groove depth is more than 10mm, and there is a silk phenomenon.
[0059] As an optional implementation, graphene material can be arranged on the surface of the finishing guide plate.
[0060] Through repeated experiments and a large amount of data comparison, the graphene material of the embodiment of the application has lighter wear of the finishing guide plate wear-resistant lining plate when the machine is taken out, fewer edge burrs and steel adhesion, and the surface condition of the guide plate lining plate is obviously improved, so that the edge quality of the finishing rolling strip can be improved, and the machine cycle can be obviously prolonged from 30 days of the prior art to more than 240 days.
[0061] In the implementation process, the rolling equipment can further include a finishing guide plate and a finishing mill, the finishing guide plate is arranged downstream of the rough rolling roller, and is used to guide the rough rolling strip into the finishing mill to obtain a finishing rolling strip.
[0062] The finishing guide plate is used to effectively center the finishing rolling strip running on the output roller, correctly guide the finishing rolling strip into the pinch roll and the coiling machine, align the finishing rolling strip with the rolling center line, and clamp the finishing rolling strip when entering the pinch roll, so as to reduce the tower shape of the steel coil.
[0063] Since the coiling guide plate clamps the finishing rolling strip, the coiling guide plate wear-resistant lining plate is most damaged in the whole steel rolling process, and deep grooves caused by friction with the finishing rolling strip will appear on the coiling guide plate wear-resistant lining plate after a long time of use.
[0064] As an optional implementation, the material of the coiling guide plate can be amorphous metal, specifically, the thickness of the amorphous metal ceramic coating on the surface of the wear-resistant lining plate of the coiling guide plate can be greater than or equal to 6 mm. Compared with the current general use of Q235-A material, the amorphous metal ceramic material provided by the embodiment of the present application can effectively withstand the severe sliding impact and friction wear of the strip edge, improve the quality of the finished strip edge, and also reduce the wear of the coiling guide plate.
[0065] In the specific implementation process, the comparison results of the wear amount of the coiling guide plate using the embodiment of the present application and the wear amount of the coiling guide plate using the prior art can be seen from the following Table 1:
[0066] Table 1. Comparison results of wear amount corresponding to different coiling guide plate materials
[0067] Comparison Amorphous metal backing Common backing Machine time 2 weeks 24 hours Wear 6-8mm 8-10mm
[0068] In the specific implementation process, the head of the finished strip reaches the heat inspection before the pinch roll, and the coiling guide plate performs two short strokes to approach the strip. After the short stroke is completed, the pressure control of the coiling guide plate is changed to a closed-loop adjustment mode until the strip production is completed.
[0069] In the current pressure control closed-loop adjustment process, the strip is in full contact with the coiling guide plate, which on the one hand increases the wear amount of the coiling guide plate, and on the other hand, a large amount of sparks are generated at the contact position of the coiling guide plate and the strip. This part of the sparks is attached to the surface of the strip after being crushed by the pinch roll, and small wrinkles or even hole defects occur during subsequent rolling production, which affects the quality of the strip edge and seriously affects the quality and cost of the rolling product.
[0070] In order to reduce the impact of the coiling guide plate on the quality of the strip edge during the coiling process of the strip, as an optional implementation, it can be judged whether the specification of the finished strip meets the first preset requirement. If not, the coiling guide plate is controlled to move away from the finished strip.
[0071] In the specific implementation process, the first preset requirement can include that the thickness of the strip is greater than 6 mm. That is, when the thickness of the finished strip is greater than 6 mm, the pressure of the coiling guide plate remains unchanged to ensure the good shape of the thicker strip. When the thickness of the finished strip is less than or equal to 6 mm, and the working state of the coiling machine meets the second preset requirement, the coiling guide plate is controlled to move away from the finished strip based on a preset distance threshold.
[0072] The second preset requirement can include that the coiling machine is stable and the coiling tension is stable. The preset distance threshold can be set according to actual application process, for example, the preset distance threshold can be set to 3 mm-5 mm. Optionally, the preset distance threshold can be 4 mm.
[0073] In the implementation process, the comparison results of the coiling guide control method of the embodiment of the present application and the coiling guide control of the prior art can be seen from Table 2 as shown below:
[0074] Table 2. Comparison results of wear amount corresponding to different coiling guide control methods
[0075]
[0076] It should be noted that in the application process, the probability of occurrence of the rolled skin / edge fine line defect on the hot rolling production line is reduced from 0.098% to 0.045%; the probability of occurrence of the steel sticking type skin is reduced from 0.067% to 0.024%; the probability of occurrence of the small skin is reduced from 0.035% to 0.021%; the probability of occurrence of the hole is reduced from 0.034% to 0.018%; the probability of occurrence of the three types of defects is reduced from 0.234% to 0.108%, and the total reduction is 0.126%.
[0077] It can be seen that the embodiment of the present application can indeed improve the strip edge quality and prolong the service life of the rolling equipment.
