Abstract
Description
Technical Field
[0001] This application belongs to the field of power facility technology, specifically relating to a design device, method and equipment for mineral cable production parameters. Background Art
[0002] With the rapid advancement of technology, proper control of production equipment in cable manufacturing processes can improve production efficiency and product yield. Therefore, the control of production equipment is crucial in the cable production process.
[0003] Mineral-coated cables, which consist of a copper sheath encasing a copper core and magnesium oxide powder as inorganic insulation separating the copper core from the sheath, can have an outermost protective sheath selected as needed. These cables are non-combustible and do not support combustion, allowing operation even near flames. The copper sheath melts at 1083℃. They are a primary choice for fire-resistant cables in some special installation applications. Currently, in the production of mineral-coated cables, magnesium oxide powder is generally used as the insulation layer. After filling the insulation layer, the mineral-coated cable needs to be rolled to the target size to meet production requirements. The rolling process is mainly based on rolling mills, which contain one or more rolling stands. Because parameters such as the rolling force of the rolling stands need to be controlled, and multiple rolling stands often require coordinated control, current solutions often involve manual operation. This control method not only has a high technical threshold, making precise control difficult for ordinary technicians, but also leads to low yield rates in mass-produced mineral-coated cables if control parameters do not meet the set standards. Summary of the Invention

[0054] The following description, in conjunction with the accompanying drawings, details the design apparatus, method, and equipment for mineral cable production parameters provided in this application through specific embodiments and application scenarios.
[0055] Example 1
[0056] Figure 1 This is a schematic diagram of the design device for mineral cable production parameters provided in Embodiment 1 of this application. Figure 1 As shown, it specifically includes the following:
[0057] The target physical parameter acquisition module 101 is used to acquire the target physical parameters of the mineral cable.
[0058] The frame quantity acquisition module 102 is used to acquire the number of rolling frames in the rolling mill unit that rolls the mineral cable;
[0059] The stand parameter acquisition module 103 is used to acquire the number of rolls and the roll pattern information of each rolling stand in the rolling mill group; wherein, the roll pattern information includes circular or elliptical through holes, the radius of the circular through hole, and the major and minor axes of the elliptical through hole;
[0060] The rolling parameter design module 104 is used to input the target physical parameters, the number of rolling mill stands, the number of rolls, and the roll pass information into a pre-built allocation model to obtain the design results output by the allocation model; wherein, the design results include the rolling parameters of each rolling mill stand in the rolling mill group.
[0061] This solution is applicable to scenarios involving parameter control of mineral cable production equipment. It is understood that the implementer of this solution can be a terminal device controlling the mineral cable production equipment, such as a control terminal, desktop computer, laptop computer, or smartphone.
[0062] Mineral-insulated cables, also known as mineral-insulated cables, have the following main advantages: Fire resistance. Because mineral-insulated cables are entirely composed of inorganic materials (metallic copper and magnesium oxide powder), they themselves do not cause fires and cannot burn or support combustion. Since copper's melting point is 1083℃ and the mineral insulation layer's melting point is above 1000℃, this type of cable can continue to supply power even in a fire near copper's melting point, making it a truly fire-resistant cable. High current carrying capacity and overload resistance. Mineral-insulated cables can operate normally at temperatures up to 250℃, with a continuous operating temperature of 105℃. This is to account for the needs of terminal sealing materials and safety. Even so, its current carrying capacity far exceeds that of other cables because mineral insulation has a better thermal conductivity than plastic, resulting in a greater current carrying capacity at the same operating temperature. Waterproof, explosion-proof, and corrosion-resistant. Thanks to its seamless metal sheath, mineral-insulated cables can be completely immersed in water, providing excellent waterproof performance. Because mineral-insulated cables use a metal sheath as a protective layer, flammable gases, oil vapors, and flames cannot reach the electrical equipment connected to the cable, thus giving the cable explosion-proof characteristics. Since copper has good corrosion resistance, no additional protection is needed under normal operating conditions. In special environments, such as those with strong corrosive effects on copper, an additional PVC outer sheath is added, providing excellent corrosion resistance. Halogen-free and non-toxic, resistant to mechanical damage, and with a long lifespan, the cable is entirely composed of inorganic materials (metallic copper and mineral insulation), so even when burning at 1000℃, it will not produce smoke, halogens, or toxic gases, making it a truly halogen-free and non-toxic cable. Because the metal sheath of the cable has a certain strength and toughness, the relative positions between the cores and between the cores and the sheath remain unchanged when the cable is subjected to bending, flattening, or torsion, preventing short circuits and maintaining electrical performance. Since the cable uses only inorganic materials, it does not age. Its service life can be calculated based on the rate of oxidation and corrosion of the copper sheath. Data shows that a 0.25mm thick sheath requires 257 years of service life at 250℃. Mineral-insulated cables typically have a sheath thickness between 0.34 and 1.05mm and operate at temperatures below 250℃, thus exhibiting a long lifespan. The copper sheath can be used as a grounding conductor. For mineral-insulated cables, a separate grounding conductor is unnecessary because the copper sheath already functions as a grounding conductor, providing good low grounding resistance. In multi-grounded neutral systems, the outer copper sheath can be used as both a grounding and neutral conductor.
[0063] The target physical parameter can be the outer diameter of the rolled copper sheath, i.e., the diameter or radius of the rolled mineral cable. In addition, the target physical parameter can also include other information, such as the thickness of the rolled copper sheath, the thickness of the magnesium oxide insulation layer, and the radius of the copper core.
[0064] In this scheme, the number of rolling stands in the rolling mill unit can be one or more. Generally, the number of rolling stands in the rolling mill unit is six or eight. The through-hole shapes of different rolling stands can be the same or different, for example, all circular, all elliptical, or partially circular and partially elliptical.
[0065] Furthermore, the number of rolls in a rolling mill stand can be two or more. Taking a two-roll rolling mill stand in a rolling mill unit as an example, with the rolls arranged, the mineral cable can be rolled into a circle after passing through the current rolling mill stand. Understandably, three or more rolls can also roll into a circle or an ellipse.
[0066] In this solution, specifically, the hole type information includes a circular via and its radius, or an elliptical via and its major and minor axes.
[0067] An allocation model can be a model used to allocate rolling tasks to each rolling stand, such as how much rolling force to use for each rolling stand, or the bite angle of each stand, etc.
[0068] The rolling parameters can include the magnitude of the rolling force or the bite angle, as well as other parameters such as the rolling temperature during the rolling process. For example, the mineral cable can be preheated before entering the rolls to give it better ductility when rolled using the current rolling mill.
[0069] In this scheme, specifically, the rolling force can be uniformly allocated based on the target physical parameters, the number of rolling stands, the number of rolls, and the pass information. For example, the total rolling force required during the rolling process can be determined based on the target physical parameters, and then the rolling force allocated to each rolling stand can be determined based on the number of rolling stands, the number of rolls, and the pass information. For example, if a rolling mill has 6 rolling stands, 2 of which are elliptical passes and 4 are circular passes, and a total rolling force of 10,000 Newtons needs to be allocated, then the two elliptical stands can be allocated 4,000 Newtons, which can be 2,000 Newtons each, and the four circular pass stands can be allocated 2,000 Newtons, 2,000 Newtons, 1,000 Newtons, and 1,000 Newtons respectively.
[0070] The allocation model can be either a machine learning model or a statistical model. The former uses sample data to learn how to allocate rolling parameters such as rolling force, resulting in a more reasonable allocation that ensures the mineral cable meets actual production needs while guaranteeing the normal operation of the rolling mill. Alternatively, the allocation model can be a statistical model that uses statistical analysis of sample data to determine historical patterns in manually allocating rolling parameters like rolling force. Based on these patterns, the rolling parameters of the rolling mill can be rationally allocated, ensuring the allocation results better align with manual allocation habits and guaranteeing both the mineral cable's performance and the normal operation of the rolling mill.
[0071] The technical solution provided in this embodiment includes a target physical parameter acquisition module for acquiring the target physical parameters of the mineral cable; a stand quantity acquisition module for acquiring the number of rolling stands in the rolling mill unit for rolling the mineral cable; a stand parameter acquisition module for acquiring the number of rolls and die type information of each rolling stand in the rolling mill unit; wherein the die type information includes circular or elliptical through holes, the radius of the circular through hole, and the major and minor axes of the elliptical through hole; and a rolling parameter design module for inputting the target physical parameters, the number of rolling stands, the number of rolls, and the die type information into a pre-constructed allocation model to obtain the design result output by the allocation model; wherein the design result includes the rolling parameters of each rolling stand in the rolling mill unit. This technical solution, by using an allocation model to determine the rolling parameters of each rolling stand, enables precise control of production equipment during the mineral cable production process, improving the production efficiency and product yield of the mineral cable.
[0072] In one feasible embodiment, optionally, the device further includes:
[0073] The initial parameter acquisition module is used to acquire the initial physical parameters of the mineral cable;
[0074] Accordingly, the rolling parameter design module is specifically used for:
[0075] The initial physical parameters, the target physical parameters, the number of rolling mill stands, the number of rolls, and the roll pass information are input into a pre-built allocation model to obtain the design results output by the allocation model.
[0076] Initial physical parameters can be those prior to rolling the mineral cable. For example, initial physical parameters include the outer diameter of the copper sheath of the mineral cable; the copper sheath is tubular, and its outer diameter is the diameter of the mineral cable before rolling. The inner diameter of the copper sheath is determined by its thickness. Other parameters include the diameter of the copper core, the thickness of the magnesium oxide powder layer, and the relative density of the magnesium oxide powder. The magnesium oxide powder, located between the copper core and the copper sheath, forms the mineral insulation layer of the mineral cable, providing insulation. Initially, it is powdered magnesium oxide, which is compacted after rolling. The magnesium oxide powder particles can be considered rigid and do not deform; during compaction, only pore compression occurs. Powder particles are displaced under various forces; smaller particles are forced into the pores between larger particles, filling these pores. Because smaller particles fill the pores, the volume occupied by the powder decreases, thus increasing its relative density.
[0077] After determining the initial physical parameters, the rolling force during the rolling process can be determined based on these parameters. The rolling force can be the force applied to the mineral cable by each rolling stand in the rolling mill, resulting in a reduction in the overall outer diameter of the mineral cable, compaction of the internal magnesium oxide powder, a decrease in the thickness of the copper sheath, and even a reduction in the diameter of the copper core. In this scheme, the rolling force can be determined based on the outer diameter of the copper sheath from the initial physical parameters.
[0078] The initial physical parameters include an outer diameter of 100 mm for the copper jacket and an outer diameter of 80 mm for the copper jacket in the standard parameters. Therefore, the rolling force of each rolling stand in the rolling mill can be determined based on the change from the initial physical parameters to the target physical parameters. Specifically, an allocation model can be used to determine the rolling force of each rolling stand in the rolling mill based on factors such as the initial physical parameters, the target physical parameters, the number of rolling stands, the number of rolls, and the pass information.
[0079] This embodiment, through such a setting, can fully consider the initial physical parameters during the process of determining the rolling parameters of each rolling mill stand, and determine the rolling parameters of the rolling mill stand based on the initial physical parameters, target physical parameters, and other factors, so as to ensure the smooth progress of mineral cable processing and improve the product yield of mineral cable.
[0080] Based on the above technical solution, optionally, the initial physical parameters include the copper jacket thickness, copper core diameter, and magnesium oxide powder particle density of the mineral cable.
[0081] The thickness of the copper jacket and the diameter of the copper core will be compressed under the rolling force after rolling, for example, the thickness of the copper jacket will become thinner and the diameter of the copper core will become smaller. As for the particle density of magnesium oxide powder, it fills the space between the copper jacket and the copper core. Due to the influence of factors such as particle gaps, the thickness of the magnesium oxide powder will also be compressed under the rolling force, which will manifest as thinning and increasing particle density.
[0082] This scheme allows for the introduction of specific information from the initial physical parameters before rolling, providing a more comprehensive data basis for the allocation of subsequent rolling parameters and making the allocation of rolling parameters more consistent with actual operating conditions.
[0083] Example 2
[0084] Figure 2 This is a schematic diagram of the structure of the design device for mineral cable production parameters provided in Embodiment 2 of this application. This solution makes further improvements based on the above embodiments. Specifically, the improvement is as follows: the device further includes a stand capacity range determination module, used to determine the upper limit rolling force of each rolling stand; correspondingly, the rolling parameter design module is specifically used to: input the target physical parameters, the number of rolling stands, the number of rolls, and the roll pass information into a pre-constructed allocation model to obtain the initial rolling force of each rolling stand output by the allocation model; if the initial rolling force is less than or equal to the upper limit rolling force of the current rolling stand, then the initial rolling force is determined as the final rolling force of the current rolling stand; if the initial rolling force is greater than the upper limit rolling force of the current rolling stand, then the current rolling stand is determined to be an over-limit rolling stand, and the allocated rolling force is determined according to the initial rolling force and the upper limit rolling force; the allocated rolling force is allocated according to the initial rolling force and the upper limit rolling force of each rolling stand to obtain the final rolling force of each rolling stand.
[0085] like Figure 2 As shown, the device includes:
[0086] The target physical parameter acquisition module 201 is used to acquire the target physical parameters of the mineral cable.
[0087] The frame quantity acquisition module 202 is used to acquire the number of rolling frames in the rolling mill unit that rolls the mineral cable;
[0088] The stand parameter acquisition module 203 is used to acquire the number of rolls and the roll pattern information of each rolling stand in the rolling mill group; wherein, the roll pattern information includes circular or elliptical through holes, the radius of the circular through hole, and the major and minor axes of the elliptical through hole;
[0089] The rolling parameter design module 204 is used to input the target physical parameters, the number of rolling stands, the number of rolls, and the roll pass information into a pre-built allocation model to obtain the design results output by the allocation model; wherein, the design results include the rolling parameters of each rolling stand in the rolling mill group.
[0090] The device further includes:
[0091] The stand capacity range determination module 205 is used to determine the upper limit rolling force of each rolling stand;
[0092] Accordingly, the rolling parameter design module 204 is specifically used for:
[0093] Based on the target physical parameters, the number of rolling mill stands, the number of rolls, and the roll pass information, the data are input into a pre-built allocation model to obtain the initial rolling force of each rolling mill stand output by the allocation model.
[0094] If the initial rolling force is less than or equal to the upper limit rolling force of the current rolling mill stand, then the initial rolling force is determined to be the final rolling force of the current rolling mill stand.
[0095] If the initial rolling force is greater than the upper limit rolling force of the current rolling stand, the current rolling stand is determined to be an over-limit rolling stand, and the allocated rolling force is determined based on the initial rolling force and the upper limit rolling force.
[0096] The allocated rolling force is distributed according to the initial rolling force and the upper limit rolling force of each rolling stand to obtain the final rolling force of each rolling stand.
[0097] Each rolling mill stand has an upper limit to its rolling force. For example, the upper limit for a rolling mill stand is 5,000 Newtons. Exceeding this limit will damage the hardware, such as the rolls. In another scenario, if the rolling force of a rolling mill stand exceeds a certain threshold, it will cause the stand to jump during rolling, which greatly affects the rolling effect. Therefore, this threshold can be defined as the upper limit of the rolling force for the rolling mill stand.
[0098] In this scheme, an allocation model is used to determine the initial rolling force for each rolling stand based on the input data. The initial rolling force is the initial output result of the allocation model for each rolling stand. After obtaining the initial rolling force, it is compared with the upper limit rolling force of each rolling stand. If the initial rolling force is less than or equal to the upper limit rolling force of the current rolling stand, the initial rolling force is determined as the final rolling force of the current rolling stand. Conversely, if the initial rolling force is greater than the upper limit rolling force of the current rolling stand, the current rolling stand is determined to be an over-limit rolling stand, and the allocated rolling force is determined based on the initial rolling force and the upper limit rolling force.
[0099] Specifically, based on the rolling effect, the initial rolling force is subtracted from 90% of the upper limit rolling force to obtain the rolling force that needs to be allocated. For example, if the initial rolling force is 5500 Newtons and the upper limit rolling force is 5000 Newtons, then subtracting 90% of the initial rolling force from the upper limit rolling force will give the rolling force that needs to be allocated, which is 1000 Newtons.
[0100] After obtaining the allocated rolling force, the allocated rolling force can be distributed according to the initial rolling force and the upper limit rolling force of each rolling stand to obtain the final rolling force of each rolling stand.
[0101] The rolling force can be allocated according to the difference between the initial rolling force and the upper limit rolling force of each rolling stand, or a target rolling stand can be determined according to the maximum value of the difference between the initial rolling force and the upper limit rolling force of each rolling stand, and the allocated rolling force can be distributed to the target rolling stand.
[0102] This embodiment provides a mechanism for secondary adjustment of the output of the distribution model based on the upper limit rolling force. This adjustment makes the actual control results more consistent with the actual working conditions of each rolling mill stand, improves the working stability of the rolling mill stand, extends the working life of the rolling mill stand, and improves the rolling effect of mineral cables.
[0103] Based on the above technical solutions, optionally, the rolling parameter design module is further specifically used for:
[0104] Identify the rolling mill stand with the same pass pattern as the over-limit rolling mill stand as the target allocation mill stand;
[0105] The allocation amount is determined based on the difference between the initial rolling force and the upper limit rolling force of the target allocation stand, so as to obtain the final rolling force of the over-limit rolling stand and the target allocation stand based on the allocation amount.
[0106] In this scheme, after determining the over-limit rolling mill stand, its pass parameters can be read first, and the target allocation mill stand can be determined from the rolling mill stands with the same pass. For example, all rolling mill stands with the same pass can be used as the target allocation mill stand, or a portion of the rolling mill stands with the same pass can be determined as the target allocation mill stand.
[0107] After determining the target allocation stand, the difference between the initial rolling force and the upper limit rolling force of each target allocation stand can be obtained to determine the rolling force allocation capacity of each target allocation stand and determine the allocation amount given to each target allocation stand, so as to obtain the final rolling force of the overloaded rolling stand and each target allocation stand.
[0108] For example, a rolling mill stand with a circular pass has an initial rolling force of 4000 N and an upper limit rolling force of 3000 N. There are two other rolling mill stands with circular passes. These two stands can be designated as target allocation stands. If the initial rolling force of each of these target allocation stands is 2000 N and the upper limit rolling force is 4000 N, then the allocation capacity of the two target allocation stands is sufficient to allocate the excess portion. Each of the two target allocation stands can allocate 1000 N. That is, after allocation, the final rolling force of the excess rolling mill stand is 2000 N, and the final rolling force of the two target allocation stands is 3000 N.
[0109] This solution, through this setup, allows for the distribution of excess material across multiple rolling mill stands with the same die shape. This distribution ensures rolling performance while eliminating the need to calculate the impact of different die shapes and increased rolling force on the shape of the mineral cable.
[0110] Based on the above technical solutions, optionally, the rolling parameter design module is further specifically used for:
[0111] If the number of target allocation stands is at least two, then the difference between the initial rolling force and the upper limit rolling force for each target allocation stand is determined;
[0112] The allocation ratio of each target allocation rack is determined based on the difference between the target allocation racks;
[0113] Based on the allocation ratio of the allocated amount to each target allocated stand, the final rolling force of the over-limit rolling stand and each target allocated stand is determined.
[0114] When there is only one target allocation stand, the allocation ability and corresponding allocation amount can be determined based on the difference between the initial rolling force and the upper limit rolling force of that target allocation stand. When there are at least two target allocation stands, the allocation ratio for each target allocation stand can be determined based on the difference between the initial rolling force and the upper limit rolling force. For example, if there is a rolling force of 5000 Newtons to be allocated, the allocation ratio can be determined based on the difference between the initial rolling force and the upper limit rolling force for each stand. For example, if there are three target allocation stands with initial rolling force and upper limit rolling force differences of 1000 Newtons, 3000 Newtons, and 6000 Newtons respectively, the allocation can be done proportionally based on the ratio of the differences, such as 1:3:6. In this case, the first target allocation stand can allocate 500 Newtons, the second target allocation stand can allocate 1500 Newtons, and the third target allocation stand can allocate 3000 Newtons, thus completing the allocation of all rolling forces.
[0115] This scheme, through a proportional allocation method, ensures that the target distribution stand still has good rolling force extension space after the allocation, allowing each rolling stand to work more stably and ensuring the production yield of mineral cables.
[0116] Based on the above technical solutions, optionally, the rolling parameter design module is further specifically used for:
[0117] If there is no rolling mill with the same roll pass as the over-limit rolling mill, or if the difference between the initial rolling force and the upper limit rolling force of the target allocation mill is less than the allocation rolling force of the over-limit rolling mill, a prompt message indicating that allocation is not possible is generated.
[0118] In one scenario, if no rolling mill stand has the same pass shape as the over-limit rolling mill stand (e.g., only the over-limit rolling mill stand has an elliptical pass shape, while the pass shapes of other rolling mill stands in the rolling mill unit are circular), a message indicating that the pass cannot be allocated can be generated.
[0119] In another scenario, if a rolling mill with the same roll pass as the over-limit rolling mill exists, it is designated as the target allocation mill. However, if the difference between the initial rolling force and the upper limit rolling force of the target allocation mill is less than the allocation rolling force of the over-limit rolling mill, a prompt message indicating that allocation is not possible can be generated.
[0120] This solution, through such a setting, can generate corresponding prompts when it is impossible to allocate the yield, thus preventing the mineral cables from failing to meet the target physical parameters after rolling, or from having some rolling mill stands with actual rolling force exceeding the upper limit, resulting in mineral cables that cannot meet the yield requirements.

This technical solution, by using an allocation model to determine the rolling parameters of each rolling stand, can precisely control the production equipment during the mineral cable production process, thereby improving the production efficiency and product yield of the mineral cable.
