Description

Technical Field

[0001] This application relates to the field of strip steel technology, and in particular to a method, apparatus, medium and coiling machine for strip steel coiling. Background Technology

[0002] When the strip is coiled in the pickling and rolling mill, the mandrel of the coiler first coils the strip head. After the number of coiling turns reaches a certain value, the mandrel then coils the strip at high speed until the finished coil comes off the line. Each time a new strip is coiled, the initial number of coiling turns at the strip head needs to be changed according to the different strip thicknesses and the wear degree of the mandrel sector plate. Due to the frequent changes in the thickness of the raw materials, the frequency of modification also increases. Sometimes, due to the busy work of the operators, the initial number of coiling turns at the strip head is forgotten to be modified, resulting in the initial number of coiling turns at the strip head being too large or too small. This affects the production rhythm of the rolling mill, reduces the output of the production line, and the long-term use of a large initial number of coiling turns at the strip head increases the wear on the mandrel sector plate and the coiling aid, reducing the service life of the mandrel sector plate and the coiling aid.

It should be understood that such uses of these terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described.

[0029] The implementation details of the technical solutions in the embodiments of this application are described in detail below:

[0030] First, it should be noted that the method for coiling strip steel proposed in this application can be applied to the field of strip steel coiling technology. For example, when coiling strip steel, current coiling machines require manual adjustment of the initial coil number at the head whenever the strip steel thickness changes. If the operator fails to adjust it due to error, the initial coil number at the head may be too large or too small. If the initial coil number at the head is too small, the quality of the finished coil will be substandard. If the initial coil number at the head is too large, it will cause excessive wear on the mandrel fan plate and the auxiliary coiler belt. Therefore, it is particularly important to automatically match the corresponding initial coil number at the head according to the strip steel thickness when coiling strip steel.

[0031] According to one aspect of this application, a method for coiling steel strip is provided. Figure 1 The flowchart illustrates a method for coiling strip steel according to an embodiment of this application. This method can be executed by a device with computational processing capabilities. The method includes at least steps 110 to 140, detailed below:

[0032] Please refer to Figure 1 In step 110, the strip thickness is obtained in response to the trigger command of the pressing aid coiler.

[0033] In this application, when the strip begins to curl, a trigger command is activated on the pressing and coiling aid to obtain the thickness of the strip at that moment. The strip thickness can be measured using either X-ray measurement or laser measurement. X-ray measurement utilizes the intensity attenuation of X-rays as they penetrate the strip to measure thickness. Laser measurement involves irradiating the strip surface with a laser beam, creating an image from the scattered light, and converting the image signal into an electrical signal using a CCD (charge-coupled device) photoelectric sensor to determine the image point position. As the strip moves, the image point moves accordingly, allowing the displacement to be calculated. During the detection process, the thickness of the moving strip is accurately measured using the double-triangulation method on the upper and lower surfaces of the laser.

[0034] In step 120, the number of initial coil turns of the strip associated with the strip thickness is obtained from the database.

[0035] In this application, the strip thickness was obtained first, and then the number of initial coil turns associated with the strip thickness was obtained from the database.

[0036] It should be emphasized that the number of initial coil turns at the beginning of the strip, which is related to the strip thickness, can be preset, setting different ranges of strip thickness and the corresponding number of initial coil turns at the beginning of the strip.

[0037] In step 130, the auxiliary winding device is controlled to press the strip steel onto the mandrel, and the mandrel is controlled to rotate at a first speed for the number of initial winding turns of the strip head.

[0038] In this application, a control coiling aid presses the strip steel onto a mandrel. The mandrel and the coiling aid press the strip's head together, allowing the strip steel to rotate with the mandrel. The mandrel is controlled to rotate through the initial number of turns at the strip's head at a first speed. The strip steel thickness is matched to the corresponding number of initial turns at the strip's head, which can significantly reduce the time required for strip head coiling, accelerate the finished coil's exit from the production line, and improve the strip coiling efficiency. Furthermore, it reduces unnecessary and prolonged strip head coiling, thereby reducing wear on the mandrel sector plate and the coiling aid, and extending their service life.

[0039] In step 140, the coiling aid is controlled to move away from the strip, and the mandrel is controlled to rotate at a second speed until the strip is coiled into a finished coil.

[0040] In this application, when the coiling aid presses against the mandrel, it presses the strip head against the mandrel. During the rotation of the mandrel, there is significant friction between the strip and the coiling aid, and between the strip and the mandrel. After the mandrel has rotated through the initial number of turns of the strip head, the strip can rotate with the mandrel due to its own friction, controlling the coiling aid to move away from the strip and operate at a high speed at a second speed, thereby improving the coiling efficiency of the strip.

[0041] In one embodiment of this application, before obtaining the number of initial coil turns of the strip associated with the strip thickness from the database in step 120, the following steps may also be performed: setting a range of strip thickness and the number of initial coil turns of the strip associated with the strip thickness within this range.

[0042] In this application, the strip thickness can be divided into a certain thickness range, and the associated number of initial coil turns can be set in different thickness ranges. Once the strip thickness is obtained, the corresponding number of initial coil turns can be directly matched, reducing the number of times operators need to work and effectively improving the strip coiling efficiency.

[0043] In one embodiment of this application, after setting the strip thickness range and the number of initial coil turns associated with the strip thickness within this range, the following step can also be performed: when the quality requirements of the finished coil change, the number of initial coil turns associated with the strip thickness can be modified.

[0044] In this application, if the quality requirements of the finished coil change, or the material specifications of the strip change, the number of initial coil turns associated with the strip thickness can be modified to adapt to different strip thicknesses. This method is applicable to a wide range of situations.

[0045] In one embodiment of this application, the initial coil number associated with the strip thickness is obtained from the database, and the initial coil number ranges from 5 to 60 coils. An excessively large initial coil number increases the wear on the winding aid and the mandrel sector plate, while an excessively small initial coil number easily causes the inner coil of the finished coil to loosen, resulting in substandard quality. An initial coil number range of 5 to 60 coils is suitable for the current strip thickness range.

[0046] In one embodiment of this application, the strip thickness range and the number of initial coil turns associated with the strip thickness within this range are divided into four segments: strip thickness < 0.45 mm, 0.45 mm ≤ strip thickness ≤ 0.6 mm, 0.6 mm < strip thickness ≤ 0.8 mm, and strip thickness > 0.8 mm.

[0047] In this application, the strip thickness is divided into four segments. When the strip thickness is < 0.45 mm, the number of initial coils at the beginning of the strip can be set to 12 coils; when the strip thickness is 0.45 mm ≤ 0.6 mm, the number of initial coils at the beginning of the strip can be set to 10 coils; when the strip thickness is 0.6 mm < 0.8 mm, the number of initial coils at the beginning of the strip can be set to 6 coils; and when the strip thickness is greater than 0.8 mm, the number of initial coils at the beginning of the strip can be set to 5 coils.

[0048] In one embodiment of this application, the mandrel includes an A-axis and a B-axis. The setting of the strip thickness range and the number of initial coils associated with the strip thickness within this range includes: setting the strip thickness range of the A-axis and the B-axis respectively, and the number of initial coils associated with the strip thickness within this range for the A-axis and the B-axis.

[0049] In this application, the mandrel includes an A-axis and a B-axis, and possibly more other axes. The A-axis and B-axis can alternately coil the steel strip to form a finished coil, thereby improving the coiling efficiency of the steel strip.

[0050] In one embodiment of this application, the first speed is less than the second speed.

[0051] In this application, the mandrel rotates at a first speed for the initial number of turns of the strip head, and then rotates at a second speed until the strip is coiled into a finished coil. When the strip head just begins to coil, it is pressed against the mandrel by an auxiliary coiler. The mandrel rotates at the first speed, which is slower than the second speed, effectively reducing wear on the auxiliary coiler and the mandrel's sector plate. The second speed is faster than the first speed, improving the efficiency of coiling the strip into a finished coil.

[0052] In summary, by pre-setting the initial coil count associated with different strip thicknesses, the operational difficulty for operators is reduced, the number of times operators need to re-enter the initial coil count each time they change strips is decreased, and the time for coiling strips into finished coils is reduced. Assuming a saving of 1 second per finished coil, each mandrel produces an average of 130 finished coils per 12-hour shift, and 7800 finished coils per mandrel per month (720 hours). Therefore, each mandrel saves a total of 2.15 hours per month. The pickling and rolling mill unit has A and B axes, producing a total of 300 tons of finished coils per hour. Assuming a profit of 250 yuan per ton of finished coil, the monthly economic benefit = saved time × reduced capacity × profit per ton of steel = 2.15 × 2 × 300 × 250 yuan = 161,000 yuan. The annual benefit = number of months × monthly benefit = 12 × 161,000 yuan = 1,935,000 yuan. This effectively increases the factory's production efficiency.

[0053] It can also reduce unnecessary long-term winding, thereby reducing the wear of the mandrel sector plate and winding aid, and extending the service life of the mandrel sector plate and winding aid.
