Background
As a non-destructive inspection means, dye tests may utilize penetrants with colored dyes to reveal surface defects that are difficult to observe by the average naked eye. The penetrating agent generally has strong penetrating capability, and after being sprayed on the surface of a workpiece to be detected, the penetrating agent penetrates into tiny pores of the surface defect of the workpiece. And after the redundant penetrating agent is cleaned, spraying the developing agent on the surface of the workpiece, and re-washing and adsorbing the penetrating agent by utilizing capillary action to form marks at the defect positions on the surface, so that the defects can be observed and analyzed conveniently.
In the service process, the continuous casting roll is subjected to alternating mechanical stress, needs to be contacted with a high-temperature casting blank and is subjected to quenching of cooling water, and cold and hot fatigue is easy to generate, so that hot cracks are generated on the roll surface. In addition, the roller surface can be corroded, scaled and wrinkled due to high-temperature oxidation and corrosion of the cooling water and fluoride ions in the protective slag, so that the roller surface is worn, the roller diameter is thinned, and the roller is scrapped under severe conditions. The severe service environment determines that the continuous casting roll is prone to surface defects. In order to save the cost, the old roller can be disassembled and the roller surface is repaired after being in online service for a period of time, and in order to more efficiently finish the repairing operation of the roller surface defects, detection and analysis are needed for the damage of the roller surface. The damage which is difficult to find can be effectively observed by utilizing the dye check, so that the repairing work of the roller surface is more targeted. The manual operation of the dye check flow in the existing factory has large duty ratio, so that the flaw detection efficiency is lower, and for continuous casting rolls with larger sizes, the manual operation is difficult to cover the whole roll surface, and errors are more likely to occur. In order to efficiently perform flaw detection analysis on the surface defects of the continuous casting rolls, it is necessary to increase the degree of automation of the dye check process.
