[0002] At present, in the galvanizing production process of strip steel, the steel elements in the strip steel are continuously melted into the zinc liquid, which leads to the generation of zinc slag.

DETAILED DESCRIPTION

[0044] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

[0046] First, the applicable application scenarios of the present application are introduced. The embodiments provided in the present application are not limited to automobile outer panels and household appliance outer panels. During the galvanizing process of the strip steel on the market, the equipment used in different processes are in different environments, which will make the zinc slag on the surface of the steel strip difficult to control, thereby affecting the quality and precision of the strip steel products.

[0047] Based on this, the embodiments of the present application provide a strip steel production method, device and electronic equipment for reducing zinc slag. The embodiments provided by the present application reduce the surface zinc slag of the initial strip steel outer plate, thereby improving the quality and precision of the target strip steel outer plate.

[0048] See also Figure 1 , Figure 1 This is one of the flow charts of a strip steel production method for reducing zinc slag provided in an embodiment of the present application. Figure 1 As shown in the figure, the strip steel production method for reducing zinc slag provided in the embodiment of the present application comprises the following steps:

[0049] S101. Based on the production specification information in the attribute information of the initial steel strip outer plate, pre-clean the initial steel strip outer plate to determine whether the reflectivity of the initial steel strip outer plate reaches a preset reflection threshold.

[0050] In this step, in the embodiment provided by the present application, after the initial steel strip outer plate is actually produced by the galvanized production line, it is first necessary to pre-clean the initial steel strip outer plate, the purpose of which is to reduce the subsequent use of chemical cleaning agents, and during the pre-cleaning process, the actual reflectivity of the initial steel strip outer plate is monitored in real time (assuming that the preset monitoring time interval is not limited to 1 hour) until the reflectivity of the initial steel strip outer plate reaches the preset reflection threshold.

[0051] It can be understood that pre-cleaning of the initial steel strip outer plate is a process of water washing or other physical cleaning methods before the device is put into production or after shutdown and maintenance, and before chemical cleaning. The role of this is to reduce the amount of chemical cleaning agents used, and the pre-cleaning step in the embodiment provided in the present application is crucial to the treatment process of the initial steel strip outer plate, because it can effectively remove dirt from the initial steel strip outer plate and prepare for subsequent chemical treatment. In addition, the pre-cleaning in the embodiment provided in the present application can also preheat the initial steel strip outer plate and increase the temperature of the initial steel strip outer plate when it enters the pickling section, which has a positive impact on improving the pickling efficiency and quality.

[0052] Among them, the initial strip steel outer plate in the embodiment provided in the present application is used to characterize the strip steel product just produced from the strip steel production line, and the initial strip steel outer plate in the embodiment provided in the present application can be specifically but not limited to: strip steel outer plate of automobiles and strip steel outer plate of home appliances, etc.

[0053] Here, it is assumed that the production specification of the external galvanizing unit in the embodiment provided in this application is 0.65 X 1500.

[0054] Among them, the attribute information in the embodiment provided in this application is used to characterize some production representation information corresponding to the above-mentioned initial strip steel outer plate itself, specifically including but not limited to production specification information, steel strip width, strip steel thickness and strip steel height, etc.

[0055] Among them, the preset reflection threshold in the embodiment provided in the present application is customized according to the attribute information of different types of initial strip steel outer panels. It is assumed that the initial strip steel outer panels in the embodiment provided in the present application are produced automobile outer panels. Therefore, the corresponding preset reflection threshold is set specifically but not limited to 93%.

[0056] Therefore, the embodiment provided in the present application can pre-clean the corresponding initial steel strip outer plate according to the production specification information of the initial steel strip outer plate, so that the reflectivity of the initial steel strip outer plate reaches the preset reflection threshold value of 93%, thereby achieving preliminary slag removal of the initial steel strip outer plate, thereby reducing the difficulty of subsequent slag removal.

[0057] S102. If the reflectivity reaches a preset reflectivity threshold, then when the target furnace pressure and the target gas content in the external annealing furnace meet the preset furnace environment rules, based on the production specification information, determine the target zinc ingot type to be added to the galvanizing solution, the target zinc liquid temperature corresponding to the galvanizing solution, and the target liquid level corresponding to the galvanizing solution.

[0058] In this step, after determining that the reflectivity of the initial steel strip outer plate in the embodiment provided in the present application reaches the preset reflection threshold, the initial steel strip outer plate needs to be sent to an external annealing device (assuming that the annealing device in the embodiment provided in the present application is specific but not limited to an external annealing furnace) for annealing treatment. Therefore, it is necessary to control and adjust the target furnace pressure and target gas content of the initial steel strip outer plate so that it meets the preset furnace environment rules, and after meeting the preset furnace environment rules, determine the dissolution rate of the initial steel strip outer plate in the galvanizing solution in the zinc liquid according to the production specification information of the initial steel strip outer plate (which can be specifically the galvanizing thickness information of the initial steel strip outer plate, etc.), and then determine the required ingot content in the galvanizing solution according to the dissolution rate, and then determine the target zinc ingot type to be added, the target zinc liquid temperature corresponding to the galvanizing solution, and the target liquid level corresponding to the galvanizing solution.

[0059] It can be understood that in the process of continuously adding the target zinc ingots to the galvanizing solution, as well as the process of dissolution reaction and galvanizing of the initial strip steel outer plate in the zinc liquid, it is necessary to ensure that the temperature of the galvanizing solution is in a relatively stable state. Long-term over-temperature production of the galvanizing solution will aggravate the iron loss of the initial strip steel outer plate and the oxidation of zinc in the galvanizing solution, thereby leading to the formation of zinc slag. Therefore, in the embodiments provided in the present application, it is necessary to preset the target zinc liquid temperature corresponding to the galvanizing solution so that the temperature of the galvanizing solution is in a relatively stable state.

[0060] It can be understood that in the process of continuously adding target zinc ingots to the galvanizing solution, the embodiments provided in the present application also need to adjust and monitor the target liquid level of the galvanizing solution in real time. At this time, it is necessary to control the target liquid level corresponding to the galvanizing solution to a suitable position to keep the target liquid level of the galvanizing solution constant and ensure normal overflow. Therefore, observing the overflow at the peephole requires smooth overflow in the width direction of the upper and lower lip surfaces, and slagging and local stagnant flow are not allowed to prevent zinc slag from adhering to the surface of the strip.

[0061] Among them, it is assumed that the process of continuously adding target zinc ingots to the galvanizing solution in the embodiment provided in the present application can be achieved by a closed-loop control automatic zinc adding device or platform in the prior art, and the target liquid level can be monitored in real time by a liquid level meter control.

[0062] Therefore, the embodiment provided in the present application further adjusts the galvanizing process of the initial steel strip outer plate by adding a target zinc ingot type to the galvanizing solution, a target zinc liquid temperature corresponding to the galvanizing solution, and a target liquid level corresponding to the galvanizing solution, thereby achieving further galvanizing of the initial steel strip outer plate, so as to achieve the purpose of reducing the zinc slag on the surface of the initial steel strip outer plate.

[0063] S103, based on the strip steel plate type information in the attribute information, determining the target parameters of the target air knife that matches the initial strip steel outer plate.

[0064] In this step, the attribute information of the initial strip steel outer plate in the embodiment provided by the present application also includes the strip steel plate type information. In the production process flow of the initial strip steel outer plate provided by the present application, the initial strip steel outer plate is pre-cleaned and annealed in an external annealing furnace, and then enters the zinc pot through the furnace nose at a certain temperature, passes through the sinking roller, the correction roller and the stabilizing roller, etc., and then exits the zinc pot. Then, it is necessary to reach a suitable zinc layer weight at the matching target air knife. At this time, it is necessary to adjust the target parameters of the target air knife so that the corresponding target parameters reach the preset specified range.

[0065] It can be understood that the initial strip steel outer plates corresponding to different plate type information will be galvanized using different air knife distances.

[0066] Therefore, the embodiment provided in the present application further adjusts the target parameters of the target air knife to achieve a galvanizing treatment with higher requirements for the initial strip steel outer plate, thereby further reducing the risk of generating zinc slag.

[0067] S104, based on the target zinc ingot type, target zinc liquid temperature, target liquid level and target parameters, perform hot-dip galvanizing on the initial steel strip outer plate, and determine the target steel strip outer plate after hot-dip galvanizing, so as to reduce the surface zinc slag of the initial steel strip outer plate.

[0068] In this step, after determining the target zinc ingot type, target zinc liquid temperature, target liquid level and target parameters, the embodiment provided in the present application adjusts and controls the corresponding equipment, devices and containers based on the above parameters to determine the target strip steel outer plate after galvanizing. The target strip steel outer plate here has been galvanized compared to the initial strip steel outer plate, and according to experimental data, the zinc slag content on the surface of the target strip steel outer plate is relatively low.

[0069] In one embodiment, based on the production specification information in the attribute information of the initial steel strip outer plate, the initial steel strip outer plate is pre-cleaned to determine whether the reflectivity of the initial steel strip outer plate reaches a preset reflectivity threshold, including the following steps:

[0070] Sub-step 201: determining the target slag removal task corresponding to the initial steel strip outer plate at different steel strip widths according to the production specification information in the attribute information of the initial steel strip outer plate.

[0071] In this step, the embodiment provided in the present application will first determine the target slag removal task of the initial strip steel outer plate under different strip steel widths based on the production specification information in the attribute information of the initial strip steel outer plate, such as the strip steel width information, wherein the wider the initial strip steel outer plate, the higher the slag removal (Fe2Al5) rate.

[0072] It can be understood that, assuming that the target slag removal task one in the embodiment provided in the present application is specifically: slag removal treatment is performed on the outer plates of 6 initial strip steel rolls with a strip width greater than 1500mm; the target slag removal task two is specifically: slag removal treatment is performed on the outer plates of 8-9 initial strip steel rolls with a strip width less than 1500mm.

[0073] Sub-step 202: for any target slag removal task, pre-clean the initial steel strip outer plate that matches the target slag removal task, and determine whether the reflectivity of the initial steel strip outer plate reaches a preset reflection threshold.

[0074] In this step, for the target slag removal task of any strip width, it is first necessary to pre-clean the corresponding initial strip outer plate, and then determine the reflectivity of the initial strip after pre-cleaning, and continue pre-cleaning when the reflectivity reaches the preset reflection threshold until the reflectivity reaches the preset reflection threshold.

[0075] It can be understood that the pre-cleaning in the embodiments provided in the present application may include but is not limited to pre-cleaning and electrolytic cleaning, etc.

[0076] Among them, the concentration of pre-cleaning can be specifically 45-55ms, the conductivity of rinsing water can be specifically <30μs / cm, the concentration of electrolytic cleaning can be specifically 50-60ms, and the temperature of alkali solution in pre-cleaning, electrolysis, water brushing and rinsing 1 and 2 stages can be specifically 75±10℃.

[0077] It is understandable that pre-cleaning is mainly for cleaning the vertical tank. Therefore, we specifically set it as follows: the tank body is drained once every 2 hours, each time for 0.5 minutes, and the reflectivity value of the initial strip steel outer plate after cleaning is further monitored and recorded once every hour, so that the reflectivity value of the outer plate after cleaning should be maintained above 93%.

[0078] In one embodiment, the preset furnace environment rule includes a preset furnace pressure rule and a preset gas content rule, and determining whether the target furnace pressure and the target gas content in the external annealing furnace meet the preset furnace environment rule in the following manner includes the following steps:

[0079] Sub-step 301: determining whether a target furnace pressure in the external annealing furnace satisfies a preset furnace pressure rule, and determining whether a target gas content in the external annealing furnace satisfies a preset gas content rule.

[0080] In this step, before the initial strip steel outer plate is fed into the external annealing equipment, it is necessary to determine whether the target furnace pressure in the external annealing furnace meets the preset furnace pressure threshold specified by the preset furnace pressure rule, and to determine whether the target gas content in the external annealing furnace meets the preset gas content threshold specified by the preset gas content rule.

[0081] It can be understood that the preset gas in the embodiments provided in the present application includes but is not limited to hydrogen. A low hydrogen content will lead to incomplete reaction, which will lead to oxidation of the outer plate of the initial strip steel and excess iron being brought into the zinc pot. Therefore, it is necessary to construct a preset furnace pressure rule and a preset gas content rule.

[0082] It is assumed that the preset furnace pressure threshold in the preset furnace pressure rule in the embodiment provided in the present application is set to 1.5HPA-2.5HPA; and the preset gas content threshold is set to 5%-7%.

[0083] Therefore, the embodiment provided in the present application reduces the risk of oxidation of the outer plate of the initial strip steel by setting the above parameters.

[0084] Sub-step 302: If the target furnace pressure satisfies the preset furnace pressure rule, and the target gas content satisfies the preset gas content rule, then determine whether the target furnace pressure and the target gas content in the external annealing furnace meet the preset furnace environment rule.

[0085] In this step, if the target furnace pressure is within 1.5HPA-2.5HPA, and the target gas content is within 5%-7%, it is determined that the target furnace pressure and the target gas content in the external annealing furnace meet the preset furnace environment rules.

[0086] In one embodiment, based on the production specification information, determining the target type of zinc ingot to be added to the zinc plating solution, the target zinc liquid temperature corresponding to the zinc plating solution, and the target liquid level corresponding to the zinc plating solution includes the following sub-steps:

[0087] Sub-step 401: Determine the aluminum content range in the galvanizing solution according to the galvanizing thickness information in the attribute information of the initial steel strip outer plate.

[0088] In this step, the dissolution rate of the initial steel strip outer plate in the galvanizing solution in the zinc liquid is determined according to the production specification information of the initial steel strip outer plate (which may be specifically the galvanizing thickness information of the initial steel strip outer plate, etc.), and then the required ingot content in the galvanizing solution is determined according to the dissolution rate.

[0089] It is understandable that when the aluminum content in the galvanizing solution is below 0.2%, the amount of iron dissolved decreases with the increase of the aluminum content. When the aluminum content exceeds 0.2%, the amount of iron dissolved increases rapidly with the increase of the aluminum content, and the number and size of the zinc slag particles will increase. Since the initial steel strip outer plate continuously takes away the zinc liquid in the galvanizing solution to form a coating, the aluminum content in the coating is much higher than the aluminum content in the zinc liquid in this process, that is to say, the coating will obtain aluminum from the galvanizing solution in excess of a proportion. The thicker the zinc layer of the initial steel strip outer plate, the smaller the proportion of aluminum taken away, and therefore the less effective aluminum is consumed.

[0090] The aluminum content in the zinc plating solution in the embodiment provided in the present application can be specifically set to: 0.22-0.24%.

[0091] Sub-step 402: determining the target type of zinc ingot to be added to the zinc plating solution according to the aluminum content range.

[0092] In this step, the embodiment provided in the present application needs to determine the content of zinc added to the galvanizing solution according to the content range of the consumed effective aluminum, and then determine the target type of zinc ingots added to the galvanizing solution.

[0093] Among them, if the added ingot ratio and coating are greater than 50g, a target zinc ingot with an aluminum content of 34% is used, and if the added ingot ratio and coating are less than 50g, a target zinc ingot with an aluminum content of 55% is used.

[0094] Sub-step 403: determining a target zinc liquid temperature corresponding to the galvanizing solution according to the production specification information of the initial strip steel outer plate.

[0095] In this step, the power of the sensor in contact with the zinc pot is controlled according to the production specification information of the initial strip steel outer plate, thereby achieving control of the target zinc liquid temperature of the galvanizing solution.

[0096] It is assumed that the target zinc liquid temperature in the embodiments provided in the present application may be specifically but not limited to 455±4°C.

[0097] It can be understood that, assuming that the production specification of the initial strip steel outer plate is 0.8, at this time, the control target zinc liquid temperature is specifically 455-458 degrees Celsius, and the sensor power is specifically 90-100 watts; assuming that the production specification of the initial strip steel outer plate is 0.6, at this time, the control target zinc liquid temperature is specifically 463 degrees Celsius, and the sensor power is specifically 130-140 watts.

[0098] Sub-step 404: determining a target liquid level corresponding to the galvanizing solution according to an adding rate of the target zinc ingot into the galvanizing solution.

[0099] In this step, the embodiment provided in the present application controls the target liquid level of the galvanizing solution at -40±5 mm according to the addition rate of the target zinc ingot into the galvanizing solution.

[0100] In one embodiment, the target parameters include a target distance and a target height. Based on the strip steel plate information in the attribute information, determining the target parameters of the target air knife that matches the initial strip steel outer plate includes the following sub-steps:

[0101] Sub-step 501: determining a target distance between a target air knife matching an initial steel strip outer plate and the initial steel strip outer plate according to the steel strip plate type information in the attribute information.

[0102] In this step, the embodiment provided in the present application determines the target distance between the target air knife and the initial strip steel outer plate (obtained from a preset strip steel shape and distance mapping table) based on the strip steel shape information in the attribute information.

[0103] Among them, the target distance in the embodiment provided in this application can be specifically set to 12-14mm.

[0104] Sub-step 502: determining a target height of the target air knife that matches the initial strip steel outer plate according to a preset air pressure value corresponding to the target air knife and a preset air pressure and height mapping table.

[0105] In this step, after the strip steel plate type information is determined, the preset air pressure value corresponding to the target air knife is determined. At this time, the target height of the target air knife is determined according to the preset air pressure value and the preset air pressure and height mapping table.

[0106] It can be understood that the greater the air knife pressure of the target air knife, the greater the amount of zinc slag on the surface of the zinc pot. Under the premise of meeting the zinc layer thickness and surface quality, the smaller the target air knife pressure, the better.

[0109] See also Figure 2 , Figure 2 This is a flow chart of the second method for producing strip steel with reduced zinc slag provided in the embodiment of the present application. Figure 1 As shown in the figure, the strip steel production method for reducing zinc slag provided in the embodiment of the present application comprises the following steps:

[0110] S201. Based on the production specification information in the attribute information of the initial steel strip outer plate, pre-clean the initial steel strip outer plate to determine whether the reflectivity of the initial steel strip outer plate reaches a preset reflection threshold.

[0111] S202. If the reflectivity reaches a preset reflectivity threshold, then when the target furnace pressure and the target gas content in the external annealing furnace meet the preset furnace environment rules, based on the production specification information, determine the target zinc ingot type to be added to the galvanizing solution, the target zinc liquid temperature corresponding to the galvanizing solution, and the target liquid level corresponding to the galvanizing solution.

[0112] S203: Based on the strip steel plate type information in the attribute information, determine the target parameters of the target air knife that matches the initial strip steel outer plate.

In this way, while ensuring the stability of the initial steel strip outer plate, small tension control is achieved, thereby reducing the force between the initial steel strip outer plate and the zinc pot roller system.

Based on the target zinc ingot type, target zinc liquid temperature, target liquid level, target tension and target parameters, the initial strip outer plate is subjected to hot-dip galvanizing treatment to determine the target strip outer plate after hot-dip galvanizing so as to reduce the surface zinc slag of the initial strip outer plate.

[0116] S206, cooling down and removing iron from the galvanizing solution after hot-dip galvanizing so as to perform slag removal treatment on other batches of initial strip steel outer plates.

[0117] In this step, after determining the target strip outer plate, the galvanizing solution needs to be cooled and iron removed. The cooling and iron removal method in the embodiment provided by this application can be specifically as follows: gradually reduce the temperature of the zinc pot, insert a high-pressure nitrogen pipe into the zinc pot, and fully stir the zinc liquid through high-pressure nitrogen, so that iron and aluminum react fully, generate Fe2Al5 top slag solid particles, and then allow the small solid zinc slag particles in the zinc pot to fully collide, forming large particles that float to the surface of the zinc pot. In the embodiment provided by this application, the temperature can be specifically reduced and then raised to 455°C.

The zinc slag defects on the surface of the initial strip steel outer plate are effectively controlled.
