Measuring device for aligning with continuous casting crystallizer and measuring method thereof

Abstract

The invention relates to a measuring device for aligning with a continuous casting crystallizer and a measuring method thereof. The technical scheme is that a mounting plate 18 of the device is fixed on a shell 13 of a sliding device 6; a lower plane of the mounting plate 18 is vertical to a center line of the shell 13; and the mounting plate 18 is fixed on a platform of a supporting adjusting bracket 7 through bolts. A detecting rod 5 is connected with a worm wheel 16 through threads; the detecting rod 5 and the worm wheel 16 are concentrically mounted in the shell 13; and a sensor 1 is arranged at the lower end of the detecting rod 5 and is connected with a digital display meter 9 through a cable 10. The measuring method of the device comprises the following steps: moving the detecting rod 5; measuring a distance L2 between an outside foot roll 11 and the sensor 1 through the sensor 1; measuring a distance L1 between an outside support roll 12 and the sensor 1; respectively taking minimum values of the distance L1 and the distance L2; calculating a pair arc delta L which is equal to the diffrence of L2 and L1 between the outside foot roll 11 and the outside support roll 12; and then adjusting the crystallizer to ensure that delta L is less than or equal to 0.3mm. The invention has the characteristics of rapid and accurate measurement.

Description

technical field [0001] The invention belongs to auxiliary equipment for continuous casting crystallizers, in particular to a continuous casting crystallizer centering measuring device and a measuring method thereof. 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 exce...

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
