Continuous casting slab defect melting equipment and its scanning positioning method and system

Abstract

The invention provides a continuous casting slab defect melting removal device and a scanning and positioning method and system thereof. The method includes the steps that an intersection point of the first upper side edge of the horizontal upper surface of a continuous casting slab and the first side edge of the vertical side surface, in the length direction, of the continuous casting slab is positioned and serves as a starting point of the continuous casting slab, and the starting point of the continuous casting blank serves as a scanning starting point of the continuous casting slab defect melting removal device; starting from the scanning starting point, scanning is performed in the upper surface and the side surface till the second upper side edge, opposite to the first upper side edge, of the upper surface is scanned, an intersection point of the second upper side edge and the first side edge in the side surface is positioned and serves as an end point of the continuous casting slab, and the end point of the continuous casting slab serves as a purging starting point of the continuous casting slab defect melting removal device; and a purging gun of the continuous casting slab defect melting removal device is adjusted and made to be positioned and aligned with the purging starting point. The continuous casting slab defect melting removal device and the scanning and positioning method and system of the continuous casting slab defect melting removal device can effectively increase the positioning speed, shorten operation time of workers, reduce operation errors of the workers and improve the work efficiency.

Description

technical field [0001] The invention relates to a melting device, in particular to a continuous casting slab defect melting device and a scanning positioning method and system thereof. Background technique [0002] The melting of defects in continuous casting slabs has always been a difficult problem for steel mills. At present, most of them use manual cleaning methods. During the manual cleaning of slabs, natural gas and oxygen are used to clean the surface of slabs with flames, which is high temperature and high risk. Sexual work, harsh working environment and high risk. [0003] Artificial flame cleaning has the following disadvantages: high temperature and high dust on the job site, long-term operation will affect the health of operators; at the same time, the weight of the purge gun and the recoil force of high-pressure oxygen, long-term operation is a difficult test for personnel endurance. Manual cleaning is a highly technical job, operators must undergo professional...

Problems solved by technology

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a continuous casting slab defect melting equipment and its scanning positioning method and system, which are used to solve the problem of using continuous casting slab defect melting equipment in the prior art. When positioning, the positioning speed is slow and the positioning is prone to deviation.
