A measuring method for the CSP casting machine frame

Abstract

The present invention discloses a method for measuring the CSP casting machine frame. By using the mold positioning pins located on the ladle turntable platform, the platform is stable, and the visibility of the positioning pins is good, which is conducive to accurate measurement. In addition, the mold positioning pins have not been adjusted since the construction. Although they are also affected by factors such as wear, their positions are closer to the design values. Taking the mold positioning pins as the relative reference for measurement, the axis of the bottom pins of the four segments and the measured dimensions of each segment positioning block are used for verification. According to the verification results, the position of the reference is reasonably adjusted and corrected. This method solves the problem that the design control points cannot be used as the measurement reference due to factors such as foundation settlement, and uses a laser tracker to carry out the CSP casting machine measurement work.

Description

Technical Field

[0001] The present invention relates to the field of measurement technology, and in particular to a method for measuring the frame of a CSP casting machine. Background Art

[0002] Due to the frequent occurrence of steel leakage in the first strand of the CSP casting machine, this measurement was carried out to solve this problem. The distribution of on-site control points is as follows Figure 1 , such as Figure 1 shown, there are 2 control points on the bottom wall of the bending section on site. However, during maintenance, the equipment in the middle of the control points is not dismantled, and there is no line of sight, so it cannot be used. Moreover, the accuracy of the control points can no longer be verified; in addition, there are 2 construction punctuation marks newly built on the mold platform during later construction based on the mold positioning pins, which can only be used as a reference; the 2 control points on the center line of the casting stream are missing and cannot be used. Therefore, currently, the conditions for measuring with an absolute reference are not available. Even if it is possible to measure with the control points as the absolute reference, the arc adjustment work cannot be completed based on the absolute reference.

[0003] A method for spatially positioning and measuring a slab continuous casting segment uses a total station to perform the spatially positioning and measuring work of the slab continuous casting segment. However, this method cannot be used for the CSP casting machine, mainly because the space in the secondary cooling chamber of the CSP casting machine is narrow, approximately only 2.5 meters wide * 3.5 meters long * 8 meters high, and the pitch angle of the total station does not meet the measurement requirements. And a method for controlling the installation accuracy of the banana beam of a continuous casting machine and a measuring tool for the basic frame of a continuous casting segment are only applicable to the measurement of slab casting machines with a small inclination angle.

[0004] Comparative Document 1: A method for spatially positioning and measuring a slab continuous casting segment adopts a simple three-dimensional coordinate control method. The spatial coordinates of the total station are determined through multi-point positioning measurement, and then the total station is used to cooperate with the equipment for positioning and installation. The measurement method of the present invention is simple, the tools used are easy to manufacture, and it is convenient to use. It can greatly improve the equipment installation efficiency and at the same time achieve the stability of the installation accuracy. However, this method cannot be used for the CSP casting machine, mainly because the space in the secondary cooling chamber of the CSP casting machine is narrow, approximately only 2.5 meters wide * 3.5 meters long * 8 meters high, and the pitch angle of the total station does not meet the measurement requirements.

[0005] Comparative Document 2: The embodiment of the present invention provides a method for controlling the installation accuracy of the banana beam of a continuous casting machine. A three-dimensional coordinate system is established with the help of a sample rod and a laser tracker, and three-dimensional data is collected for the key parts of the banana beam. Debugging is carried out according to the difference between the collected spatial data and the designed spatial data to ensure the equipment installation accuracy requirements. This invention is only applicable to the measurement of slab casting machines with a small inclination angle and cannot be applied to the measurement of the CSP casting machine.

[0006] Comparative Document 3: A measuring tool for the segment basic frame of a continuous casting machine, which includes a laser tracker, an upper sampling shaft of the zero segment, a lower sampling shaft of the zero segment, and a segment sampling shaft with coaxial measuring wheels at both ends. The upper sampling shaft of the zero segment and the lower sampling shaft of the zero segment are respectively installed in the upper U-shaped support of the zero segment and the lower U-shaped support of the zero segment of the segment basic frame; the two measuring wheels of the segment sampling shaft are leaned against a set of positioning plates of the segment basic frame; the laser tracker is fixed on the basic frame of the last segment of the segment through a tracker base, and the target mirror of the laser tracker is placed on the upper sampling shaft of the zero segment, the lower sampling shaft of the zero segment or the segment sampling shaft. This Comparative Document 3 uses the upper sampling shaft of the zero segment, the lower sampling shaft of the zero segment and the segment sampling shaft as auxiliary tools, and measures the spatial positions of the positioning components of each segment through a laser tracker, which can not only ensure the measurement accuracy, but also greatly improve the measurement efficiency, and well solve the problem that it is not easy to measure and adjust the segment basic frame. This invention is only applicable to the measurement of slab casting machines with small inclination angles and cannot be applied to the measurement of CSP casting machines. Summary of the Invention

[0007] In order to solve the problem that the arc adjustment measurement work cannot be completed with an absolute reference, the purpose of the present invention is to provide a measurement method for the CSP casting machine frame. By using the fact that the mold positioning pin is located on the ladle turret platform, the platform is stable, the positioning pin has good visibility, which is conducive to accurate measurement, and the mold positioning pin has not been adjusted since its construction. Although it is also affected by factors such as wear, its position is closer to the design value. The mold positioning pin is used as a relative reference for measurement, and the axis of the bottom pins of the four segments and the measured dimensions of each segment positioning block are used for verification. According to the verification results, the position of the reference is reasonably adjusted and corrected.

[0008] The biggest difficulty in using this method for measurement is that: affected by the measurement space, the instrument pitch angle, and the on-site distribution of the positioning pins and positioning blocks, the laser tracker cannot complete the measurement in one station and needs to be transferred multiple times for measurement.
