Problems solved by technology

[0004] The centering device provided by VAI relies entirely on manual visual inspection, and judges whether it is centered by visually checking the bubble position of the alcohol level, and cannot display the distance between the foot roller and the first backup roller. Position deviation, and the deviation value between the two is very important for the continuous casting process, if it cannot be controlled within the specified range, it will cause safety hazards to the entire process
In addition, field engineers generally feel that the operation of this device is very inconvenient. Since the effective deviation value cannot be given, it is difficult to accurately install and position the crystallizer, so the adjustment time is long and the workload is heavy. These problems seriously hinder safe and efficient production. Work

Abstract

The invention relates to a continuous casting crystallizer centering measuring device and a measuring method thereof. Its technical scheme is: the mounting plate 18 of this device is fixed on the housing 13 in the sliding device 6, the lower plane of the mounting plate 18 is perpendicular to the centerline of the housing 13, and the mounting plate 18 is fixed on the support adjustment frame 7 by bolts. on the platform. The detection rod 5 and the worm wheel 16 are threadedly connected and concentrically installed in the housing 13 ; the lower end of the detection rod 5 is equipped with a sensor 1 , and the sensor 1 is connected to the digital display meter 9 through a cable 10 . The measurement method of this device is to move the detection rod 5, measure the distance L2 between the outer foot roller 11 and the sensor 1 through the sensor 1, and then measure the distance L1 between the outer back-up roller 12 and the sensor 1, and take the minimum value respectively; calculate the outer foot roller The arc alignment between the roller 11 and the outer support roller 12 is ΔL=L2-L1, and then the crystallizer is adjusted so that ΔL≤0.3mm. The invention has the characteristics of fast and accurate measurement.

Description

technical field [0001] The invention belongs to auxiliary equipment for continuous casting crystallizers, in particular to a centering measuring device for continuous casting crystallizers. Background technique [0002] The slab produced by continuous casting equipment is the raw material for rolling steel. The quality of the slab directly affects the quality of the final product. The mold is a very important part of the continuous casting machine. It is a forced water-cooled bottomless ingot mold. The "heart" of casting equipment. The installation accuracy of the continuous casting mold directly affects the quality of the slab. In particular, the arc alignment accuracy of the wide surface foot roll of the crystallizer and the first support roll (hereinafter referred to as the first support roll) on the upper part of the O sector in the bending section is an important factor affecting the surface quality of the slab, and once the arc deviation exceeds the limit, Also can ...
