Device and method for correcting curvature radius of roller table at bending segment of continuous casting machine

Abstract

The invention discloses a device for correcting curvature radius of a roller table at a bending segment of a continuous casting machine. The device comprises a roller spacing measuring device and a data processing device, wherein the roller spacing measuring device comprises a support, a fixed scale fixed on the support, a movable scale movably arranged on the support, a laser measuring head arranged on the movable scale and an operational processor, the laser measuring head acquires measured data from the fixed scale and the movable scale and transmits the data to the operational processor, and the operational processor calculates the spacing between the roller tables at the neighboring bending segments according to the measured data; and the data processing device calculates a corrected value of the curvature radius of the roller table at the segment according to the spacing between the roller tables at the neighboring bending segments which is detected by the roller spacing measuring device. By utilizing the device and the method for correcting the curvature radius of the roller table at the bending segment of the continuous casting machine, the curvature radius of the roller table at the bending segment of the continuous casting machine can be automatically corrected with high accuracy, short correction time and high efficiency so as to effectively improve the production efficiency of the continuous casting machine and produce considerable economic benefit.

Description

technical field [0001] The invention relates to the technical field of detection of the curvature radius of a roller table in a bending section of a continuous casting machine, in particular to a correction device and method for the curvature radius of a roller table in a bending section of a continuous casting machine. Background technique [0002] In China's domestic steelmaking plants, the roller table of the bending section of the continuous casting machine is generally designed with a straight arc. In order to ensure the successful casting of the mold at one time, the curvature radius of the roller table of the bending section must be corrected. In addition, after a steel breakout accident occurs in the continuous casting machine, the roller table in the bending section must be replaced, which also requires recalibration of the curvature radius of the roller table in the bending section. There is also a bending section roller table used for offline maintenance, and the ...
