Online continuous caster outer arc segment row arc measurement method

Abstract

The invention discloses an online continuous caster outer arc segment row arc measurement method. A continuous caster roller clearance instrument moves straight forward along the outer arc segment row, three probes of the roller clearance instrument measures the distances with the adjacent three outer arc roller surfaces in real time, and the disatcnes respectively represent the diatnce between the roller clearance instrument corresponding to the probe position and the outer arc roller; when the third probe measures the top of the corresponding outer arc roller, deviation values between the second probe measurement position and the corresponding outer arc roller top and the first probe measurement position and the corresponding outer arc roller top can be obtained respectively; the distances with the corresponding outer arc rollers detected by the second probe and the first probe can be corrected according to the deviation values, and the distance values after correction are obtained; the difference value between the second probe and the first probe and the corresponding outer arc rollers after correction can be obtained after calculation, when the third probe detects the distance of the corresponding outer arc roller is zero, the difference value represents the arc value of the continuous caster outer arc segment row. The method can measure the arc value of the continuous caster outer arc segment row, ensures normal operation fo the continuous casting equipment and the quality of the casting blank.

Description

technical field [0001] The invention relates to an on-line measurement method for the radian of the outer arc roll row of a continuous casting machine. Background technique [0002] Any arc continuous casting machine has a continuous casting curve, which has an important influence on the internal quality and surface quality of the continuous casting slab. The continuous casting machine relies on the arc arrangement of two rows of continuous casting rolls to realize the bending and straightening of the slab according to the specified continuous casting curve. Each continuous casting roll has a corresponding radian value. If the radian value is too large or too small, it will cause unreasonable stress distribution of the slab, which will not only lead to quality problems of the slab, but also cause damage to the equipment. Therefore, the detection of the radian of the continuous casting roll row is an important link to ensure the normal operation of the continuous casting equ...

AI Technical Summary

Problems solved by technology

At present, most continuous casting machines lack reliable and real-time continuous casting roll arc measurement data, and cannot implement real-time measurement of continuous casting roll arc, and with the operation of continuous casting equipment, the working conditions of continuous casting roll change greatly, resulting in The change of its radian value will affect the normal operation of the continuous casting equipment and the quality of the slab
