Control method for purging gun for continuous casting billet defect smelting removal equipment

Abstract

The invention provides a control method for a purging gun for continuous casting billet defect smelting removal equipment. The purging gun is arranged on a purging swinging angle structure. The purging swinging angle structure is connected with a three-axis mechanical arm. A rotary servo motor is arranged on the three-axis mechanical arm. When steel plate surface X-direction defects are removed, a 15-degree included angle is formed between a gun head of the purging gun and the steel plate Z-direction axis, and a 15-degree included angle is formed between the gun head and the steel plate Y-direction axis. A 15-degree included angle is formed between the gun head of the purging gun and the steel plate Y-direction axis, and a 15-degree included angle is formed between the gun head and the steel plate Z-direction axis. When steel plate side X-direction defects are removed, a 15-degree included angle is formed between the gun head of the purging gun and the steel plate Y-direction axis, and a 15-degree included angle is formed between the gun head and the steel plate Z-direction axis. When steel plate corner X-direction defects are removed, a 15-degree included angle is formed between the gun head of the purging gun and the steel plate corner X-direction axis. When steel plate corner Y-direction defects are removed, a 15-degree included angle is formed between the gun head of the purging gun and the steel plate corner Y-direction axis. According to the control method, the labor intensity of operators can be relieved and purging quality can be improved.

Description

technical field [0001] The invention relates to a purge gun for continuous casting slab defect melting equipment, in particular to a control method for the continuous casting slab defect melting equipment for the purging gun. Background technique [0002] The defects of continuous casting slabs are mainly divided into surface defects, internal defects and shape defects. The melting of defects in continuous casting slabs has always been a difficult problem for steel mills. At present, the defects of continuous casting slabs are mainly cleaned manually, and the cleaning process mainly relies on visual observation to ensure the surface quality of the steel plate to the maximum extent. [0003] Manual cleaning is a highly technical job, operators must undergo professional training, and special operating certificates are required for specific positions. The cleaning quality of the continuous casting slab is greatly affected by the skill level of the personnel. In order to ensure...

AI Technical Summary

Problems solved by technology

When purging, if the angle between the purge gun and the steel plate is not good, it will directly lead to the decline of the purging quality

During manual cleaning, the operator mainly relies on experience to adjust the angle between the purge gun and the steel plate. At the same time, the purge gun is relatively heavy, and it is laborious for workers to hold the purge gun.

It can be seen that the whole operation process mainly relies on manual operation, the degree of mechanization is low, the labor intensity of operators is relatively high, and the quality of blowing is low
