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.
