[0047] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0048] In order to solve the problem of interrupted pouring caused by the taper alarm during the pouring process, the embodiment of the present invention provides a method for controlling the width adjustment cylinder of the chamfering crystallizer, such as Figure 1 As shown, the method includes:

[0049] S101, during the pouring process of the chamfered crystallizer, selecting the taper of the chamfered crystallizer based on the steel grade parameters;

[0050] S102, pre-centering and assembling the ingot starter head so that the ingot starter head and the chamfering crystallizer are centered;

[0051] S103, detaching the ingot starter from the chamfering mold and reassembling it. If the distances between the ingot starter and the narrow surfaces of the copper plates on both sides of the chamfering mold are different, centering and adjusting the ingot starter relative to the chamfering mold.

[0052] Through the above technical scheme, the chamfered crystallizer width adjustment cylinder control method provided by the present invention can solve the problems in the prior art of the taper alarm during pouring, the inability of pouring stability to meet production needs, resulting in pouring interruption and increased production costs. The present invention effectively reduces the problems of the crystallizer taper alarm during the pouring process, the pouring interruption and increased production costs by designing a crystallizer foot roller with a disc spring, different taper settings for different steel grades, a chamfered ingot head gasket, the centering of the ingot rod on the ingot rod car, the centering of the ingot head in the crystallizer, the operation method for confirming the connection accuracy between the ingot head and the ingot rod, the ingot head crystallizer centering measurement tool and the method for determining the cause of the taper alarm.

[0053] The above scheme sets different crystallizer tapers according to different steel grades. The dummy rod is centered before pouring. The dummy rod car ensures that the dummy rod is centered on the dummy rod car through the centering cylinder, and measures the position of the dummy rod from the edge of the guide roller to control the distance from the edge of the guide roller on both sides. A measuring tool is made to measure the distance between the dummy head and the narrow copper plate of the crystallizer to ensure that the distance from the narrow surface of the crystallizer on both sides is controlled at a certain value. When the dummy head is loaded into the crystallizer and the distance from the narrow surface of the copper plate on both sides is measured, the dummy head is separated from the crystallizer and loaded into the crystallizer again, and the distance between the two sides of the dummy head and the narrow surface of the crystallizer is measured again to verify the flexibility of the connection between the dummy rod and the transition section to avoid the situation where the dummy head is well centered in the crystallizer but deviates after leaving the crystallizer, causing the taper to deviate.

[0054] In one embodiment, the step of selecting the taper of the chamfered crystallizer based on the steel grade parameters includes:

[0055] The carbon content of the steel is greater than 0.4%, and the alloy content is greater than 1%, and the set taper of the crystallizer is 1.0-1.1%;

[0056] For other steel types, the set taper of the crystallizer is 1.2-1.4%.

[0057] Specifically, different crystallizer tapers are set for different steel grades. The tapers of steel grades with carbon content greater than 0.4% and alloy content greater than 1% are controlled at 1.0-1.1%, and those of other steel grades are controlled at 1.2-1.4%.

[0058] In one embodiment, the pre-centering and assembling of the starter head so that the starter head and the chamfered crystallizer are centered comprises:

[0059] Measuring the distance between the ingot starter and the narrow surfaces of the copper plates on both sides of the chamfered crystallizer;

[0060] The same spacing between the narrow surfaces of the copper plates on both sides of the starter head and the chamfering crystallizer is selected so that the starter head and the chamfering crystallizer can be pre-assembled in a centered manner.

[0061] The present application makes a measuring tool to measure the distance between the ingot starter and the narrow copper plate of the crystallizer to ensure that the distance between the two sides and the narrow surface of the crystallizer is controlled at 12-15mm; when the ingot starter is installed in the crystallizer and the distance between the two sides and the narrow surface of the copper plate is measured, the ingot starter is separated from the crystallizer and installed in the crystallizer again, and the distance between the two sides of the ingot starter and the narrow surface of the crystallizer is measured again to verify the flexibility of the connection between the ingot starter rod and the transition section, so as to avoid the ingot starter being well-aligned in the crystallizer and offset after leaving the crystallizer, resulting in taper deviation.

[0062] In one embodiment, after the starter head is separated from the chamfering mold and assembled again, if the distance between the starter head and the narrow surface of the copper plates on both sides of the chamfering mold is different, the starter head is adjusted relative to the chamfering mold, including:

[0063] Separating the starter head from the chamfering crystallizer;

[0064] Arranging the starter head at the same position as during the pre-centering assembly and installing it into the chamfering crystallizer to reinstall the starter head;

[0065] Measure the distance between the reinstalled ingot starter head and the narrow copper plate of the chamfered crystallizer. If the distance between the reinstalled ingot starter head and the narrow copper plate of the chamfered crystallizer is different, adjust the position of the chamfered crystallizer until the reinstalled ingot starter head and the chamfered crystallizer are aligned.

[0066] Specifically, the dummy bar is centered before pouring. The dummy bar car ensures that the dummy bar is centered on the dummy bar car through the centering cylinder, and the position of the dummy bar from the edge of the guide roller is measured. The distance between the two sides of the dummy bar and the edge of the guide roller is guaranteed to be 40±1mm.

[0067] Specifically, Figure 3 As shown, the measuring tool 1 is a right-angled shape made of an iron sheet, and there are scale lines on the surface of the iron sheet, 15mm-12mm; the crystallizer copper plate 2, the ingot starter 3. The measuring process is to insert the measuring tool into the gap between the ingot starter 3 and the crystallizer copper plate 2, and judge the distance between the ingot starter 3 and the crystallizer copper plate 2 according to the scale line corresponding to the insertion depth. During the measurement, both sides of the ingot starter 3 are measured with the measuring tool to ensure that the distance between the two sides of the ingot starter 3 and the crystallizer copper plate 2 is consistent.

[0068] It should be noted that the chamfered crystallizer starter head gasket should be a chamfered gasket with a width of 20mm and an angle of 15° to avoid the starter head from squeezing the chamfered foot roller after it leaves the lower mouth of the crystallizer, causing a taper alarm problem.

[0069] In one embodiment, the method further includes:

[0070] Before the pouring process of the chamfered crystallizer is started, the preload force of all the disc springs on the narrow surface foot roller connecting rod of the chamfered crystallizer is adjusted.

[0071] Specifically, during the continuous casting of molten steel, the connection rod of the mold foot roller is connected by a disc spring, and the preload force of the disc spring is 12-14KN, which has a buffering effect. The above-mentioned disc spring-connected mold foot roller is composed of a group of 10 disc springs. The preload force of the disc spring during assembly is 12-14KN, which reduces the taper alarm when subjected to a large top force while ensuring accuracy.

[0072] In one embodiment, the method further includes:

[0073] Adjusting the position of the narrow side foot roller of the chamfering crystallizer in the opposite direction to the casting billet;

[0074] The narrow side foot rollers are positioned in a direction away from the chamfered crystallizer, and the first row of narrow side foot rollers are 0 mm lower in the opposite direction relative to the ingot;

[0075] The narrow surface rollers in the second row are 0.3-0.5 mm lower in the opposite direction of the casting;

[0076] The narrow surface rollers in the third row are 0.8-1.0 mm lower in the opposite direction of the casting billet;

[0077] The narrow surface rollers in the fourth row are 1.2-1.4 mm lower in the opposite direction of the casting.

[0078] Specifically, there are 4 rows of foot rollers on the narrow side of the crystallizer. The foot rollers are lowered by 0mm in the opposite direction of the ingot compared to the narrow copper plates on the crystallizer. The foot rollers in the first row are lower by 0.3-0.5mm, the foot rollers in the second row are lower by 0.8-1.0mm, and the foot rollers in the fourth row are lower by 1.2-1.4mm.

[0079] Exemplarily, the present application adopts a crystallizer foot roller connected by a disc spring as the connecting rod, so that when the ingot head comes out of the lower mouth of the crystallizer, the rigid force is avoided to cause the crystallizer taper to deviate and an alarm is generated; there are 4 rows of foot rollers on the narrow side of the crystallizer, and the relative position of the crystallizer foot rollers and the copper plates on the narrow side of the crystallizer is controlled from top to bottom according to the gradient; the chamfered crystallizer ingot head gasket uses a chamfered gasket; different crystallizer taper controls are used for different steel grades to avoid taper alarms caused by inappropriate tapers for high-strength steel grades; the ingot rod is centered by the centering cylinder to ensure that the distance between the two sides of the ingot rod and the guide rod is The edge positions of the rollers are consistent; a measuring tool is made to measure the gap between the starter head and the narrow side of the copper plate to ensure that the starter head is centered in the crystallizer; after the starter head is centered in the crystallizer, the starter head is removed from the crystallizer and then put back into the crystallizer, and the distance between the starter head and the narrow side copper plate of the crystallizer is measured again to ensure that the starter head is centered in the crystallizer and remains centered after leaving the crystallizer; a method for locking the cause of the crystallizer taper alarm is used to determine whether the taper alarm is caused by operation or equipment based on the casting length, which is convenient for troubleshooting and analysis.

[0080] In one embodiment, the method further includes:

[0081] When the chamfering crystallizer generates a taper alarm, the casting length of the casting billet is determined;

[0082] If the casting length of the ingot is not less than 1.29m, eliminate the fault of the chamfering mold width adjustment cylinder equipment;

[0083] If the casting length of the ingot is less than 1.29 m, the operational problems are eliminated.

[0084] Exemplarily, if the casting length of the casting strand is less than 1.29 m, the operational problems of S101 - S103 are eliminated.

[0085] Specifically, when a taper alarm occurs, the cause of the crystallizer taper alarm is determined based on the pouring length when the alarm occurs. If the pouring length exceeds 1.29m, the main cause of the taper alarm is a failure of the width adjustment cylinder equipment. If the pouring length is within 1.29m, it is caused by operational reasons.

[0086] It should be noted that the starter head enters the foot roller area when the casting length is 0.9m, and the starter head is out of the mold foot roller area when the casting length is 1.29m. The main reason is that the rigid contact between the starter head and the foot roller will cause the crystallizer taper to fluctuate. Therefore, according to the casting length of the crystallizer taper alarm, it can be judged whether the starter head is out of the foot roller area, thereby determining the cause of the crystallizer taper alarm.

[0087] In summary, in the stage of continuous casting of molten steel, the present application includes a crystallizer foot roller connecting rod connected by a disc spring, and a buffering effect is achieved by setting the preload force of the disc spring to 12-14KN; the crystallizer narrow side foot rollers are 4 rows, and the foot rollers are lower than the narrow side copper plates of the crystallizer in the opposite direction of the ingot, that is, the first row of foot rollers are 0mm lower, the second row of foot rollers are 0.3-0.5mm lower, the third row of foot rollers are 0.8-1.0mm lower, and the fourth row of foot rollers are 1.2-1.4mm lower; The dummy head gasket of the angle crystallizer is a chamfered gasket with a width of 20mm and an angle of 15°, which ensures that the dummy head squeezes the chamfered foot roller after exiting the lower mouth of the crystallizer, causing a taper alarm problem; different crystallizer tapers are set for different steel grades, and the taper of steel grades with carbon content greater than 0.4% and alloy content greater than 1% is controlled at 1.0-1.1%, and that of other steel grades is controlled at 1.2-1.4%; the dummy rod is centered before pouring, and the dummy rod car uses a centering cylinder to ensure the dummy rod is centered. The ingot rod is in a centered state on the ingot rod car, and the position of the ingot rod from the edge of the guide roller is measured, and the distance on both sides from the edge of the guide roller is guaranteed to be 40±1mm; a measuring tool is made to measure the distance between the ingot head and the narrow copper plate of the crystallizer to ensure that the distance on both sides from the narrow surface of the crystallizer is controlled at 12-15mm; when the ingot head is loaded into the crystallizer and the distance on both sides from the narrow surface of the copper plate is measured, the ingot head is separated from the crystallizer and loaded into the crystallizer again, and the distance between the ingot head on both sides and the narrow surface of the crystallizer is measured again to verify the flexibility of the connection between the ingot rod and the transition section to avoid the ingot head being well centered in the crystallizer and offset after leaving the crystallizer, causing taper deviation; when a taper alarm occurs, the cause of the taper alarm of the crystallizer is judged according to the casting length when the alarm occurs. If the casting length exceeds 1.29m, the main cause of the taper alarm is the failure of the width adjustment cylinder equipment. If the casting length is within 1.29m, it is caused by operational reasons. The method for controlling the alarm of the hydraulic cylinder for adjusting the width of the crystallizer during the pouring process can effectively avoid the problem of pouring interruption caused by the taper alarm during the pouring process, reduce the pouring interruption accidents caused by production abnormalities, and reduce production costs.

[0088] Furthermore, as a response to the above Figure 1 In order to realize the method shown in the figure, the embodiment of the present invention also provides a chamfering mold width adjustment cylinder control device for the above Figure 1 The device embodiment corresponds to the aforementioned method embodiment.

[0089] A selection unit 21 is used to select the taper of the chamfering mold based on the steel grade parameters during the pouring process of the chamfering mold;

[0090] A configuration unit 22, used for pre-centering and assembling the starter head, so that the starter head and the chamfering crystallizer are centered;

[0091] The adjustment unit 23 is used to detach the ingot starter from the chamfering mold and then reassemble it. If the distance between the ingot starter and the narrow surface of the copper plates on both sides of the chamfering mold is different, the ingot starter is adjusted relative to the chamfering mold.

[0092] The processor includes a kernel, and the kernel retrieves the corresponding program unit from the memory. One or more kernels can be set, and a chamfering mold width adjustment cylinder control method is implemented by adjusting kernel parameters, which can solve the pouring interruption problem caused by the taper alarm during the pouring process.
