Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel strip cold rolling, in particular to stainless steel strip cold rolling equipment and a cold rolling method thereof. Background Art

[0002] Cold-rolled stainless steel strip plays a crucial role in stainless steel production, accounting for approximately 70% of stainless steel production and representing the primary form of market consumption. Market requirements for stainless steel products are constantly increasing, not only in terms of steel grade, specifications, performance, and surface characteristics, but also in terms of improved production efficiency and lower costs to enhance competitiveness. The rapid growth of stainless steel production has led to rising prices for raw materials, such as nickel, scrap steel, ore, and coal. This has put pressure on stainless steel producers to increase costs and reduce profits, prompting manufacturers to develop new processes, technologies, and high-capacity equipment to reduce costs. Over the past decade, stainless steel production technology has made substantial progress in cutting-edge technologies, including thin slab rolling mills, strip casting, hot metal stainless steel smelting, and continuous rolling, annealing, and pickling lines, building on the foundations of advanced refining (particularly AOD), continuous casting, and wide-width multi-roller rolling.

[0003] Currently, stainless steel strips need to be processed using cold rolling equipment during production and processing. However, due to the lack of an effective guiding mechanism when performing cold rolling operations on the steel strips, the cold rolling equipment in the existing technology is very likely to deviate during operation and stress deformation. This deviation not only causes deformation defects such as wavy shapes and edge folding in the strips, but also affects the appearance and dimensional accuracy of the product.

[0009] After the rolling mill is started, the stainless steel strip enters the rolling mill smoothly with the help of the guide mechanism. At this time, the drive part is turned on and uses the power of its output end to drive the upper roller to move downward in the workbench, realizing the precise adjustment of the distance between the upper roller and the lower roller, thus preparing for the rolling process of the stainless steel strip.

The side of the cleaning component 2 away from the extension component 3 is fixedly connected to the rolling component 4, and the other side of the rolling component 4 is fixedly connected to the flattening component 5, and the other side of the flattening component 5 is fixedly connected to the pressing and expanding component 6;

[0047] See also Figure 1-Figure 3 The rolling element 1 includes a workbench 11, a driving member 12 is fixedly connected to the top of the workbench 11, an upper roller shaft 13 is slidably connected to the inner side of the workbench 11, an output end of the driving member 12 is fixedly connected to the side of the upper roller shaft 13, a lower roller shaft 14 is rotatably connected to the side of the workbench 11 away from the upper roller shaft 13, and a guide mechanism 15 is fixedly connected to the side of the workbench 11;

[0048] After the rolling mill is started, the stainless steel strip enters the rolling mill smoothly with the help of the guide mechanism 15. At this time, the driving member 12 is turned on and uses the power of its output end to drive the upper roller 13 to move downward in the workbench 11, so as to achieve precise adjustment of the distance between the upper roller 13 and the lower roller 14, thus preparing for the rolling process of the stainless steel strip.

[0049] See also Figures 1-6 The guide mechanism 15 includes a guide frame 151, the side of the guide frame 151 is fixedly connected to the workbench 11, the side of the guide frame 151 is fixedly connected to a fixed frame 152, the side of the fixed frame 152 away from the guide frame 151 is fixedly connected to a motor 153, the output end of the motor 153 is fixedly connected to one end of the screw rod 156 located above, and a belt pulley is provided on the output end of the motor 153. The inner side of the belt pulley is in rolling connection with the side of the belt 155, and the side of the guide frame 151 close to the fixed frame 152 rotates. A pulley 154 is rotatably connected to the guide frame 151, which is fixedly connected to a screw rod 156 located below through a fixing pin. A belt 155 is sleeved on the pulley 154. The upper and lower sides of the guide frame 151 are rotatably connected to screw rods 156. The upper and lower sides of the guide frame 151 are slidably connected to movable plates 157. The inner side of the movable plate 157 is threadedly connected to the side of the screw rod 156. The middle part of the two movable plates 157 is fixedly connected to a limiting mechanism 158. The upper and lower sides of the guide frame 151 are provided with limiting grooves 159.

[0050] In order to achieve precise guidance of stainless steel strips of different widths, a double-screw 156 transmission structure is adopted. After starting the motor 153, the output end of the motor 153 drives the upper screw 156 to rotate inside the guide frame 151, and at the same time drives the belt pulley to rotate. The belt pulley drives the pulley 154 on the guide frame 151 through the belt 155. The pulley 154 uses the fixed pin to make the lower screw 156 rotate synchronously. The upper and lower screws 156 work together to drive the movable plate 157 to move relative to each other in the guide frame 151, thereby driving the limit mechanism 158 to adjust the position.

[0051] Through the linkage of the double screw rods 156, the spacing of the limit mechanism 158 is adjusted according to the actual width of the stainless steel strip entering the guide frame 151, avoiding the error of the traditional single adjustment method. The structure of the belt 155 transmission and the connection with the fixed pin ensures the high synchronization of the movement of the upper and lower screw rods 156, ensuring the balanced movement of both sides of the limit mechanism 158, effectively improving the adjustment stability. The precisely positioned limit mechanism 158 can reliably guide the stainless steel strip.

[0052] See also Figure 1-Figure 7 , the limiting mechanism 158 includes a limiting block 1581, the inner side of the limiting block 1581 is rotatably connected to a ball 1582, the side of the limiting block 1581 away from the ball 1582 is rotatably connected to a rotating wheel 1583, both sides of the limiting block 1581 are fixedly connected to a limiting shaft 1584, one end of the limiting shaft 1584 away from the limiting block 1581 is slidably connected to the inner side of the limiting groove 159, the upper and lower sides of the limiting block 1581 are fixedly connected to a connecting shaft 1585, the other end of the connecting shaft 1585 is fixedly connected to a threaded rod 1586, the threaded rod 1586 is threadedly connected to a limiting plate 1587, the other end of the threaded rod 1586 is rotatably connected to a slider 1588, the side of the slider 1588 away from the threaded rod 1586 is rotatably connected to the movable plate 157, and the side of the slider 1588 is slidably connected to the inner side of the guide frame 151;

[0053] During the guiding process of the stainless steel strip, the movable plate 157 is connected to the limit block 1581 through the slider 1588, driving the limit block 1581 to move in the guide frame 151. The position of the limit block 1581 is adjusted according to the stainless steel strips of different widths entering the guide frame 151, ensuring that the stainless steel strip is always in the center of the rolling equipment, thereby improving the adaptability of the equipment to materials of different specifications.

[0054] The ball 1582 rotatably arranged on the inner side of the limit block 1581 can effectively reduce contact friction when guiding stainless steel strips of different thicknesses, reduce the risk of scratching the surface of the stainless steel strip, and ensure the surface quality of the product. When processing thinner stainless steel strips, the limit plate 1587 is rotated to move it downward on the threaded rod 1586. After the abutment state with the slider 1588 is released, the limit block 1581 is rotated to drive the limit shaft 1584 to complete a 180-degree rotation in the limit groove 159. At this time, the runner 1583 on the limit block 1581 is abutted against the stainless steel strip, and then the limit plate 1587 is rotated again to make it tightly abut against the side of the slider 1588, thereby stabilizing the position of the limit block 1581, so that the runner 1583 can provide stable guidance for the thinner stainless steel strip, effectively avoiding the problem of strip deviation during loading, avoiding the interference of deviation on the operation of the roller, improving the stability and production efficiency of the stainless steel strip rolling, reducing the scrap rate, and reducing production costs;

[0055] See also Figures 1-8 , the present invention provides a technical solution: the cleaning component 2 includes a support frame 21, the inner side of the support frame 21 is rotatably connected to a roller 22, and both sides of the top of the support frame 21 are fixedly connected to a contact mechanism 23;

[0056] During the continuous rolling process of the stainless steel strip, the external coil receiving component plays a traction role, driving the stainless steel strip after rolling to contact with the roller 22 and move smoothly. The contact mechanism 23 arranged on both sides of the roller 22 can fit the upper and lower surfaces of the stainless steel strip and carry out cleaning work simultaneously, which can timely remove the rolling oil, metal debris and other impurities remaining on the surface of the stainless steel strip, effectively avoiding surface scratches, indentations and other quality defects caused by residual impurities, and greatly improving the surface finish and quality of the product;

[0057] See also Figures 1-9 The contact mechanism 23 includes a contact frame 231, and both sides of the contact frame 231 are fixedly connected to contact blocks 232. The side of the contact block 232 away from the contact frame 231 is fixedly connected to the support frame 21. The side of the contact frame 231 is slidably connected to a slide rod 233, and the other end of the slide rod 233 is fixedly connected to a connecting plate 234. The side of the connecting plate 234 is fixedly connected to a scraper 236, and the other side of the connecting plate 234 is rotatably connected to a cleaning roller 237.

[0058] Under the traction of the winding component, the stainless steel strip moves smoothly on the roller 22, and the connecting plate 234 drives the scraper 236 to fit the side of the stainless steel coil to clean the stainless steel coil. The scraper 236 can quickly remove the rolling oil, metal debris and other impurities remaining on the side of the stainless steel coil, effectively avoiding problems such as irregular coil shape and surface scratches caused by the accumulation of impurities;

[0059] On the side of the connecting plate 234 away from the scraper 236, a rotating cleaning roller 237 can perform a second wiping and cleaning of the area cleaned by the scraper 236. The soft and fine material of the cleaning roller 237 can completely remove fine impurities and residual stains that the scraper 236 failed to completely remove, ensuring that the side of the stainless steel coil is clean. At the same time, the rotating design of the cleaning roller 237 can reduce friction with the side of the stainless steel coil, avoiding secondary damage to the strip during the cleaning process.

[0060] When the scraper 236 contacts and cleans the side of the stainless steel coil, when the squeezing force generated by the scraper 236 and the stainless steel coil exceeds the tensile force of the first spring 235, the first spring 235 will quickly contract, driving the slide rod 233 to slide the connecting plate 234 in the contact frame 231;

[0061] The pressure between the scraper 236 and the stainless steel coil is thereby protected and adjusted, preventing damage such as extrusion dents and scratches on the side of the stainless steel coil caused by excessive contact force, thereby protecting the appearance of the product. At the same time, the elastic buffer can also prevent the scraper 236 from accelerated wear or deformation due to long-term excessive pressure, thereby extending the service life of the scraper 236. The adaptive pressure adjustment mechanism ensures the stability of the cleaning process. Regardless of whether there are local unevenness on the surface of the stainless steel coil, the scraper 236 can be guaranteed to clean with appropriate force, thereby improving the reliability of the overall cleaning work.
