Online measuring device for outer arc arc-alignment precision of continuous casting machine

Abstract

The invention discloses an online measuring device for outer arc arc-alignment precision of a continuous casting machine. The online measuring device comprises a shell body, wherein the shell body isdivided into a rear part chamber and a front part chamber by means of a partition plate, a control module is arranged in the rear part chamber, a baffle plate is arranged in the front part chamber andis arranged on the partition plate by means of bolts, an arc-alignment plate is I shaped and the middle part thereof is positioned between the baffle plate and the partition plate, springs are arranged on two sides of the arc-alignment plate, both ends of the springs are connected to two sides of the partition plate and two sides of the rear end surface of the arc-alignment plate separately, a vertical guide groove is formed in the middle part of the arc-alignment plate, a roller is arranged on the partition plate and is positioned in the vertical guide groove, adjusting bolts are arranged ontwo sides of the middle part of the arc-alignment plate and are arranged on the partition plate by means of fixing blocks, the end surfaces of the adjusting bolts are pressed against the inner side of the rear end surface of the arc-alignment plate, a tilt angle sensor is arranged on the rear end surface of the arc-alignment plate, a proximity switch is arranged on the front end surface of the arc-alignment plate, and the tilt angle sensor and the proximity switch detect signals and transmit the signals to the control module. The online measuring device realizes online measurement of arc alignment precision, does not affect the operation rate of the casting machine, improves the arc alignment precision of the continuous casting machine, realizes the tracking of the arc alignment precisionof the continuous casting machine, and prolongs the service life of fan-shaped section equipment.

Description

technical field [0001] The invention relates to an online measuring device for the accuracy of outer arc alignment of a continuous casting machine. Background technique [0002] The outer arc of the continuous casting machine refers to the arrangement of the rollers on the outer arc surface of the continuous casting machine, which is one of the important parameters to ensure the accuracy of the continuous casting machine. Poor outer arc of continuous casting machine is an important cause of defects such as slab corner cracks and internal cracks, and severe alignment defects are also one of the main factors leading to low service life of sector rollers. At the same time, as the radian of the basic accuracy of the continuous casting machine, that is, the arrangement between the segments and the arrangement relationship between the rollers in the segment will also be affected by factors such as abnormal roller bearings, abnormal installation, and abnormal operations in the prod...

AI Technical Summary

Problems solved by technology

During the production process of the continuous casting machine, due to the deformation and settlement of the support frame of the sector, the wear of the rollers of the sector, and the collapse of the surface, etc., the arc of the sector will be poor.
