Description

Technical Field

[0001] The present invention relates to the technical field of rolling mills, and in particular to a silicon steel rolling mill. Background Art

[0002] With the increasing demand for electrical steel sheets, higher requirements are put forward for the rolling quality and efficiency of silicon steel materials. During the rolling process of traditional silicon steel rolling mills, due to low rolling accuracy and low rolling efficiency, it is difficult to meet the needs of modern electrical steel sheet production;

[0003] After retrieval, a Chinese patent with the publication number CN110153193B discloses a rolling mill for adjusting pressure compensation deflection, belonging to the field of rolling mills. It includes: a machine base, a roll bearing block A and a roll bearing block B, a lower roll and an upper roll that are respectively installed on the roll bearing blocks A and B through bearings at both ends and are installed in parallel with each other, and a control system; in addition, it further includes a pressure regulating device, wherein the pressure regulating device includes: a compensation pressure plate with an arc-shaped contact surface, a lifting rod fixedly installed on the compensation pressure plate, a spring pressing plate that can move up and down along the lifting rod, a linear stiffness spring installed on the lifting rod between the spring pressing plate and the compensation pressure plate, a frame installed on the machine base, and a lifting plate that can move up and down relative to the frame; the spring pressing plate is fixedly installed on the lifting plate. The present invention is a rolling mill for adjusting pressure compensation deflection with a simple and reasonable structure, capable of adjusting pressure compensation deflection, and having more uniform rolling thickness.

[0004] Although in the above technology, through the design of the pressure regulating device, the arbitrary adjustment of the compensation pressure can be realized according to the magnitude of the acting force and the reaction force between the roll and the rolled piece, thereby improving the thickness uniformity of the steel plate rolling. In actual production, the production of strip steel requires multiple passes of rolling, and the rolling force in each pass is different. However, in the above technology, the rolling pressure is adjusted adaptively according to the magnitude of the acting force and the reaction force between the roll and the rolled piece, so that the rolling pressure cannot be controlled, resulting in the same rolling pressure in each pass, and thus the quality of the strip steel finished product is poor.

Detailed implementation manners

[0041] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the specific embodiments cited do not limit the present invention.

[0042] Refer to Figures 1 to 15 As shown, a silicon steel rolling mill of the present invention includes: a conveyor frame 1, on the top of the conveyor frame 1, a plurality of first electric rollers 101 are installed, and at one end of the conveyor frame 1, a controller 102 is installed;

[0043] A rolling mechanism 2, there are five rolling mechanisms 2, and they are distributed in a linear array at one end of the conveyor frame 1;

[0044] A driving mechanism 3, there are five driving mechanisms 3, and they are respectively arranged at adjacent positions of the rolling mechanism 2;

[0045] The rolling mechanism 2 includes a U-shaped plate 201, a hydraulic cylinder 202, a support roller 203, and a lower pressing roller 204. Through holes 205 are respectively provided at the top of the side walls at both ends of the U-shaped plate 201. At the top end of the inner wall of the through hole 205, a hydraulic cylinder 202 is fixedly connected. The output end of the hydraulic cylinder 202 is fixedly connected with a moving block 206, and the moving block 206 is slidably connected with the U-shaped plate 201; the two moving blocks 206 are jointly rotatably connected with a lower pressing roller 204, and a support roller 203 is rotatably connected to the inner wall of the U-shaped plate 201 below the lower pressing roller 204. A pressure sensor 207 is installed at the bottom of the through hole 205, and both the pressure sensor 207 and the hydraulic cylinder 202 are electrically connected to the controller 102;

[0046] The driving mechanism 3 includes a support base 301, a motor 302, a driving gear 303, a driven gear 304, a connecting shaft 305, and a universal shaft 306. At one end of the top of the support base 301, a driving gear 303 is rotatably connected. Above the driving gear 303 on the support base 301, a driven gear 304 is rotatably connected. The driving gear 303 is meshed with the driven gear 304. At the adjacent end of the top of the support base 301 where the driving gear 303 is located, a motor 302 is fixedly connected. The output end of the motor 302 is meshed with the driving gear 303. One end of the driving gear 303 is fixedly connected with the support roller 203 through a connecting shaft 305, and one end of the driven gear 304 is connected with the lower pressing roller 204 through a universal shaft 306. The motor 302 is electrically connected to the controller 102;

[0047] In this embodiment, the feeding end of the conveying frame 1 is located at one end of the controller 102. The electrical connection between the controller 102 and the hydraulic cylinder 202 is achieved by using a hydraulic control system, such as a hydraulic pump, a hydraulic valve, etc., to connect with the hydraulic cylinder 202 to control the hydraulic cylinder 202. In addition, the pressure sensor 207 is a device or apparatus that can sense pressure signals and convert the pressure signals into available output electrical signals according to certain rules. During operation, first place the silicon steel at the feeding end of the conveying frame 1, then turn on the first electric roller 101 to convey the silicon steel and convey it to the rolling mechanism 2. At this time, turn on the motor 302. Driven by the motor 302, the driving gear 303 will rotate, driving the driven gear 304 to rotate. At the same time, the driving gear 303 will drive the connecting shaft 305 to rotate, further driving the support roller 203 to rotate. The driven gear 304 will drive the universal shaft 306 to rotate, further driving the lower pressing roller 204 to rotate. At this time, the support roller 203 and the lower pressing roller 204 will rotate synchronously in opposite directions. When the motor 302 is turned on, the hydraulic cylinder 202 is opened at the same time, allowing it to drive the moving block 206 to move downward, further driving the lower pressing roller 204 to move downward to roll the silicon steel. During the downward movement of the moving block 206, it will contact the pressure sensor 207. During the rolling process, the pressure sensor 207 will sense the downward pressure of the moving block 206, that is, the rolling pressure, and transmit the data signal to the controller 102. The controller 102 will control the rolling pressure according to the data signal. There are five rolling mechanisms 2, enabling the silicon steel to be rolled in five passes. Currently, for high-grade silicon steel SG25WV1300, the hot-rolled raw material has a thickness of 2.3. In the traditional technology, it takes 7 passes to roll the finished product to 0.245. At the current rolling mill speed, it takes at least 138 minutes to roll one coil. By shortening the 7 passes to 5 passes, the rolling time can be effectively shortened. The rolling pressures of the five passes are respectively sensed by five pressure sensors 207 and controlled by the controller 102 to reasonably distribute the reduction ratio of each pass. Through five-pass high-efficiency and steady-state rolling, it takes 98 minutes to roll one coil of sheet, thereby reducing the power consumption of the rolling mill, the oil consumption of the rolling oil, shortening the rolling mileage, and reducing the roll consumption.

[0048] Further, as Figure 4 and Figure 5 shown, the U-shaped plate 201 is respectively provided with sliding grooves 208 at both ends of the through hole 205. Both ends of the moving block 206 are fixedly connected with sliding blocks 209, and the sliding blocks 209 are slidably connected with the sliding grooves 208;

[0049] In this embodiment, through the design of the sliding blocks 209 and the sliding grooves 208, the moving block 206 can be smoothly slidably connected with the U-shaped plate 201, making the movement of the moving block 206 more stable, and further making the movement of the lower pressing roller 204 more stable.

[0050] Further, as shown in Figure 2 and Figure 6 , one end of the driven gear 304 extends to the outside of the support base 301 and is connected to the universal shaft 306 through the first flange 3061. One end of the lower pressing roller 204 extends to the outside of the moving block 206 and is connected to the universal shaft 306 through the second flange 3062;

[0051] In this embodiment, through the design of the first flange 3061 and the second flange 3062, the universal shaft 306 can be smoothly connected to the driven gear 304 and the lower pressing roller 204, so that the driven gear 304 can smoothly drive the lower pressing roller 204 to rotate.

[0052] Further, as shown in Figure 6 , the universal shaft 306 includes a first universal joint 3063, a second universal joint 3064, a sliding rod 3065 and a sleeve 3066. One end of the first universal joint 3063 is provided with a sliding rod 3065, one end of the second universal joint 3064 is provided with a sleeve 3066, and the sliding rod 3065 is slidably connected to the sleeve 3066;

[0053] In this embodiment, since the lower pressing roller 204 needs to move up and down during the rolling process, through the design of the sliding rod 3065 and the sleeve 3066, the universal shaft 306 can be telescoped, so as not to affect the up and down movement of the lower pressing roller 204.

[0054] Further, as shown in Figure 7 and Figure 8 , a plurality of grooves 3067 are circumferentially arranged on the side wall of the sliding rod 3065, and a plurality of protrusions 3068 are circumferentially arranged on the inner wall of the sleeve 3066. The grooves 3067 are slidably connected to the protrusions 3068;

[0055] In this embodiment, through the design of the grooves 3067 and the protrusions 3068, the sliding rod 3065 can smoothly drive the sleeve 3066 to rotate, so that the driven gear 304 can smoothly drive the lower pressing roller 204 to rotate.

[0056] Further, as shown in Figures 9 to 11 , it further includes a cooling mechanism 4. The cooling mechanism 4 is arranged at the end of the conveyor frame 1. The cooling mechanism 4 includes a cooling box 401, a water tank 402, a spray pipe 403, a nozzle 404 and a water pump 405. The bottom of the cooling box 401 is communicated with the water tank 402 through a water guide pipe 406. One end of the water tank 402 is communicated with the water pump 405. A spray pipe 403 is arranged inside the cooling box 401 near one end of the conveyor frame 1. A plurality of nozzles 404 are arranged at the bottom of the spray pipe 403. The output end of the water pump 405 is communicated with the spray pipe 403 through a first connecting pipe 407;

[0057] In this embodiment, after the silicon steel rolling is completed, it needs to be cooled. At this time, the water pump 405 is turned on. Under the action of the water pump 405, the cooling water in the water tank 402 will flow into the spray pipe 403 and be sprayed out from the nozzles 404 at the bottom of the spray pipe 403, so as to realize the cooling of the silicon steel. In addition, the residual cooling water on the silicon steel will drip from both ends into the water guide pipe 406 and flow back to the water tank 402 through the water guide pipe 406, so as to realize the recycling of the cooling water. In actual use, a cooling rod can be set in the water tank 402 to cool the cooling water, so as to improve the cooling effect of the cooling water.

[0058] Further, as Figure 9 to Figure 11 shown, the cooling box 401 is provided with a feeding port 408 on the side wall at one end of the conveying frame 1, a discharging port 409 is provided at the end of the cooling box 401 far from the feeding port 408, and a plurality of second electric rollers 410 are installed inside the cooling box 401 below the spray pipe 403;

[0059] In this embodiment, through the design of the feeding port 408, the silicon steel can smoothly enter the cooling box 401. Through the design of the second electric rollers 410, the silicon steel can smoothly move and be transported in the cooling box 401. Through the design of the discharging port 409, the silicon steel can smoothly discharge from the cooling box 401.

[0060] Further, as Figure 10 and Figure 11 shown, an arc-shaped pipe 411 is arranged at one end of the cooling box 401 inside the discharging port 409. A plurality of nozzles 412 are obliquely arranged at the bottom of the arc-shaped pipe 411. An air pump 413 is fixedly connected to one end of the outer wall of the cooling box 401. The output end of the air pump 413 is communicated with the arc-shaped pipe 411 through a second connecting pipe 414;

[0061] In this embodiment, the convex part of the arc-shaped pipe 411 faces one end of the feeding port 408, and the nozzles 412 are inclined towards the feeding port 408. The air pump 413 is used to convey air into the arc-shaped pipe 411, so that the air is sprayed out from the nozzles 412, thereby blowing the residual cooling water on the silicon steel to both ends and enabling the cooling water to quickly flow away from the silicon steel.

[0062] Further, as Figure 11 , Figure 12 and Figure 14 shown, a filler 415 is arranged above the spray pipe 403 inside the cooling box 401. An exhaust passage 416 is communicated with the top of the cooling box. A first filter screen 417 is slidably connected to one end of the exhaust passage 416, and a second filter screen 418 is slidably connected to one end of the water guide pipe 406;

[0063] In this embodiment, the structure of the packing 415 is a V-shaped baffle arranged in a linear array, and the V-shaped baffle is horizontally arranged. The design of the packing 415 increases the flow time of the steam, thereby increasing the condensation time of the steam, enabling the steam to condense into water droplets on the packing 415 and drip back onto the surface of the silicon steel for cooling. The steam passing through the packing 415 will be discharged through the exhaust passage 416. The first filter screen 417 can filter out the iron dust in the steam, thus avoiding the impact of the iron dust on the health of the staff. In addition, the design of the second filter screen 418 can filter the cooling water flowing back into the water tank 402, thereby avoiding excessive impurities in the cooling water and affecting the quality of the strip steel.

[0064] Further, as Figures 12 to 15 shown, one end of the side wall of the exhaust passage 416 is provided with a first through groove 419, and a first limiting groove 420 is provided at the position of the first through groove 419 inside the exhaust passage 416. Both the first through groove 419 and the first limiting groove 420 are slidably connected to the first filter screen 417. One end of the side wall of the water guide pipe 406 is provided with a second through groove 421, and a second limiting groove 422 is provided at the position of the second through groove 421 on the inner wall of the water guide pipe 406. Both the second through groove 421 and the second limiting groove 422 are slidably connected to the second filter screen 418;

[0065] In this embodiment, the design of the first through groove 419 and the first limiting groove 420 enables the first filter screen 417 to be smoothly slidably connected to the exhaust passage 416, and the design of the second through groove 421 and the second limiting groove 422 enables the second filter screen 418 to be smoothly slidably connected to the water guide pipe 406.

[0066] Working principle: When rolling silicon steel, first place the silicon steel at the feeding end of the conveyor rack 1, that is, the end far from the cooling mechanism 4. Then turn on the first electric roller 101 to convey the silicon steel and convey it to the rolling mechanism 2. At this time, turn on the motor 302. Driven by the motor 302, the driving gear 303 will rotate, driving the driven gear 304 to rotate. At the same time, the driving gear 303 will drive the connecting shaft 305 to rotate, further driving the supporting roller 203 to rotate. The driven gear 304 will drive the universal shaft 306 to rotate, further driving the pressing roller 204 to rotate. At this time, the supporting roller 203 and the pressing roller 204 will rotate synchronously and in opposite directions. When the motor 302 is turned on, the hydraulic cylinder 202 is opened at the same time, driving the moving block 206 to move downward, further driving the pressing roller 204 to move downward to roll the silicon steel. During the rolling process, the pressure sensor 207 senses the rolling pressure and transmits the data signal to the controller 102. The controller 102 controls the rolling pressure according to the data signal. There are five rolling mechanisms 2, enabling the silicon steel to be rolled in five passes. In addition, the rolling force of the silicon steel in each pass is adjusted according to the rolling condition of the silicon steel, thereby improving the rolling efficiency and quality of the silicon steel. After the silicon steel is rolled, it will enter the cooling mechanism 4 and enter the interior of the cooling box 401 from the feeding port 408 at one end of the cooling box 401. At this time, turn on the second electric roller 410 in the cooling box 401 to enable the silicon steel to smoothly enter the cooling box 401. At the same time, turn on the water pump 405. Under the action of the water pump 405, the cooling water in the water tank 402 will flow into the spray pipe 403 and be sprayed out from the nozzles 404 at the bottom of the spray pipe 403, thereby realizing the cooling of the silicon steel. The steam generated during cooling will float upward to the packing 415. Some steam will be cooled at the packing 415 and condensed into water droplets, which will drip back onto the silicon steel to cool it again. The steam passing through the packing 415 will continue to float upward and be discharged from the exhaust passage 416. The cooling water remaining on the surface of the silicon steel will flow back into the water tank 402 from both ends of the silicon steel. At this time, turn on the air pump 413. The air pump 413 injects air into the arc-shaped pipe 411 and sprays it out from the nozzle 412, thereby blowing the cooling water remaining on the silicon steel to both sides, enabling the cooling water to quickly flow away from the silicon steel and flow into the water tank 402. In actual use, a cooling rod can be set in the water tank 402 to cool the cooling water, thereby improving the cooling effect of the cooling water. The cooled silicon steel will be discharged from the discharge port 409 at one end of the cooling box 401.
