[0041] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims. In the several embodiments provided in this application, it should be understood that the disclosed apparatus and methods can also be implemented in other ways, and the apparatus embodiments described below are merely exemplary.

[0042] like Figure 1 As shown, this application provides a control method for multi-mode rolling production. The execution entity of this method can be a server or a controller, etc., including:

[0043] Step S110: Obtain the first dimension information and the first weight information of the slab.

[0044] For example, the first dimension information and the first weight information can be obtained by acquiring the production plan of the casting machine in a multi-mode rolling production line.

[0045] Step S120: Based on the first size information and first weight information of the slab, obtain the production plan information of the slab, wherein the production plan information includes the second size information and second weight information of the target product.

[0046] For example, the second dimension information and the second weight information can be obtained by acquiring the production plan of the target product of the rolling mill in a multi-mode rolling production line.

[0047] Step S130: Based on the first dimension information, the first weight information, the second dimension information, and the second weight information, determine the rolling mode of the slab, wherein the rolling mode includes a single-slab rolling mode, a headless rolling mode, and a semi-headless rolling mode.

[0048] For example, the target thickness information of the target product can be obtained through the second dimension information mentioned above. The quantity of target products that can be produced from the slab can be determined using the first weight information, the second weight information, and the target thickness information. Based on the quantity of target products that can be produced, the rolling mode of the slab is determined. For instance, when the quantity of target products is 1, the rolling mode of the slab is determined to be single-piece rolling. When the quantity of target products is less than or equal to a preset quantity, and the preset quantity is greater than 1, the rolling mode of the slab is determined to be semi-endless rolling. When the quantity of target products is greater than the preset quantity, the rolling mode of the slab is determined to be endless rolling.

[0049] By acquiring the initial dimensions, weight, and production plan information of the slab produced in the casting machine, the quantity of the target product that can be produced from the current slab can be determined, and thus the rolling mode of the slab can be determined. Therefore, by acquiring the production status of the slab in the casting machine and the specification requirements of the target product in the rolling mill in real time, the rolling mode of the rolling mill can be automatically confirmed and adjusted. This reduces management difficulty and the number of operational steps for management personnel, thereby achieving high-quality rolling control, saving management costs, reducing mode changeover time, and improving production efficiency.

[0050] In one feasible implementation, the above-described control method based on multi-mode rolling production further includes:

[0051] Step S210: Determine the target conveying speed of the slab according to the above rolling mode.

[0052] For example, the target conveying speed mentioned above is the speed at which the casting machine conveys the slab to the rolling mill.

[0053] Since different rolling modes require different numbers of slabs to be rolled, determining the target conveying speed of the slabs by rolling mode can achieve continuous rolling of the slabs, prevent slab accumulation from affecting the rolling effect, and thus improve the practicality of the production line and the quality of the finished product.

[0054] In one feasible implementation, determining the target conveying speed of the slab according to the rolling mode includes:

[0055] Step S310: When the rolling mode is endless rolling, determine the target conveying speed based on the rolling speed of the mill; and / or,

[0056] Step S320: When the rolling mode is single-block rolling or semi-endless rolling, the target conveying speed is determined based on the rolling speed of the mill and the first dimension information.

[0057] For example, the rolling speed mentioned above is the production speed of a single product of the target product by rolling according to the second size information and the second weight information of the target product.

[0058] Because of the continuity inherent in endless rolling or semi-endless rolling mills, the slab conveying speed can be controlled based on the mill's rolling speed, ensuring rolling efficiency. However, in both single-slab rolling and semi-endless rolling, new slabs need to be conveyed during the transfer process, requiring a certain amount of time for placement. Therefore, the available conveying time for the next slab needs to be determined based on the mill's rolling speed. Then, based on this available conveying time, the placement time for the next slab, and the slab's initial dimensions, the target conveying speed for the next slab to be conveyed to the mill input when the previous slab is completed can be determined in single-slab rolling or semi-endless rolling.

[0059] Therefore, determining the target conveying speed of the slab based on the continuity of the rolling mode can save the replacement time between different slabs, enable continuous rolling of slabs, improve rolling efficiency, and thus improve the practicality of the production line and the quality of finished products.

[0060] In one feasible implementation, the above-described control method based on multi-mode rolling production further includes:

[0061] Step S410: Roll the slab according to the above rolling mode to obtain the target product.

[0062] Step S420: Obtain the current rolling status of the slab, wherein the current rolling status includes the feeding and discharging status of the mill.

[0063] Step S430: Determine the current conveying speed of the slab based on the current rolling conditions and the target conveying speed.

[0064] For example, the aforementioned feeding conditions refer to the accumulation and idle status of the mill's feed inlet. The accumulation condition includes the quantity and duration of accumulated slabs, while the idle status includes the time when no slabs are present at the mill's feed inlet. The aforementioned discharge condition refers to the matching status between the current dimensions of the target product at the mill's discharge outlet and the aforementioned second dimension information. If accumulation is determined at the mill's feed inlet based on the aforementioned feeding conditions, the current conveying speed can be determined based on the accumulation quantity, accumulation time, and target conveying speed. If the rolling quality of the mill is determined not to meet the production plan based on the aforementioned discharge conditions, conveying can be stopped, and an alarm message can be issued.

[0065] By monitoring the feeding and discharging conditions of the rolling mill, the stacking status of the mill and the intelligent rolling of the slab can be determined. Adjusting the target conveyor speed based on the feeding and discharging conditions can improve the rolling quality of the mill, enhance the intelligence of the production line, and thus improve the practicality of the production line and the quality of the finished product.

[0066] In one feasible implementation, the above-described control method based on multi-mode rolling production further includes:

[0067] Step S510: Determine the shearing position of the slab based on the first dimension information mentioned above;

[0068] Step S520: Based on the above shearing position and the above rolling mode, determine the shearing monitoring range of the above slab.

[0069] Since there may be situations where the slab needs to be sheared according to the production plan during the production of the target product, the shearing position of the slab can be determined by the above-mentioned first dimension information. Determining the shearing monitoring range based on the shearing position and rolling mode can improve the quality of shearing monitoring and save monitoring costs.

[0070] In one feasible implementation, obtaining the production plan information for the slab based on its first size information and first weight information includes:

[0071] Step S610: Obtain the composition information of the above slab;

[0072] Step S620: Determine the yield information of the slab based on the first weight information and the component information mentioned above;

[0073] Step S630: Determine the second weight information of the target product based on the above-mentioned yield information and the first weight information.

[0074] For example, the above yield information is the ratio of the first weight information and the second weight information of the slab after rolling.

[0075] Since there may be some loss and error in the slab during the rolling process, the yield of the slab can be determined by the composition information and the first weight information of the slab. A certain weight of slab can be reserved in advance based on the yield and the second weight information to make up for the loss and error, thereby improving the yield of multi-rolling mode production lines, thus improving rolling quality and the practicality of the production line.

[0076] In one feasible implementation, determining the rolling mode of the slab based on the first dimension information, the first weight information, the second dimension information, and the second weight information includes:

[0077] Step S710: If the difference between the length information in the first dimension information and the length information in the second dimension information is greater than a first preset threshold, determine that the rolling mode is a headless rolling mode; and / or,

[0078] Step S720: If the difference between the length information in the first dimension information and the length information in the second dimension information is less than or equal to the first preset threshold, determine that the rolling mode is a semi-endless rolling mode; and / or,

[0079] Step S730: If the difference between the length information in the first dimension information and the length information in the second dimension information is less than or equal to the second preset threshold, the rolling mode is determined to be a single-piece rolling mode, wherein the first preset threshold is greater than the second preset threshold.

[0080] By obtaining the first and second dimension information of the slab produced in the casting machine to determine the rolling mode, the efficiency of mode switching can be improved. By obtaining the production status of the slab in the casting machine and the specification requirements of the target product in the rolling mill in real time, the rolling mode of the rolling mill can be automatically confirmed and adjusted, which can reduce management difficulty and reduce the number of operation steps for management personnel. This can achieve high-quality rolling control, save management costs, reduce mode switching time, and improve production efficiency.

[0083] The second acquisition module 202 is used to acquire the production plan information of the slab based on the first size information and the first weight information of the slab, wherein the production plan information includes the second size information and the second weight information of the target product.

[0084] The determining module 203 is used to determine the rolling mode of the slab based on the first dimension information, the first weight information, the second dimension information, and the second weight information, wherein the rolling mode includes a single-slab rolling mode, a headless rolling mode, and a semi-headless rolling mode.
