Problems solved by technology

However, the existing domestic steel mills often wait for the steel billets to be stacked and then manually write, which will inevitably lose real-time performance. Not only is the numbering inaccurate, but also the readability of manual writing is poor. If various information is to be correctly reflected, the labeling process must be selected After the billet is cut and still moving on the track of the continuous casting machine, the temperature of the billet is nearly 1,000 degrees at this time. In such a harsh working environment, manual writing is unrealistic. Non-manual billet marking methods such as mechanical striking , high-pressure paint spraying type, etc., the disadvantage of mechanical hitting type is that it will permanently damage the surface of the billet, and the font should not be too large; high-pressure paint spraying type is easy to cause damage to the equipment under long-term high-pressure conditions
However, the traditional marking spraying system has low work efficiency, the font is not smooth, difficult to identify, and the spraying quality is poor and easy to fall off

Description

technical field [0001] The invention relates to the field of arc spraying devices, in particular to a motion control system for an arc spray gun. Background technique [0002] At present, in order to track the quality of steel billets, the iron and steel industry requires that the steel billets produced by continuous casting be numbered and printed on the surface of the billets. In the subsequent inspection or production process, if the quality problems of the billet are found, the production can be tracked according to its number Various information of this billet, early detection and resolution of product quality problems in production. However, the existing domestic steel mills often wait for the steel billets to be stacked and then manually write, which will inevitably lose real-time performance. Not only is the numbering inaccurate, but also the readability of manual writing is poor. If various information is to be correctly reflected, the labeling process must be selec...
