Abstract

As market demands tighten, ISD Dunaferr Zrt. is placing increasing emphasis on improving the quality of its products. Line Scanner equipment used in rolling mills can identify most surface defects, but the majority of metallurgical faults are located beneath the surface (e.g. inclusions, cavity, gas bubbles, etc.). There is no standardized device for detecting them, only ultrasonic and microscopic testing is possible. In addition, it should be noted that some of the defects detected on the surface (e.g. surface cracks) can only be determined by microscopic testing, whether they are metallurgical or due to the parameters of the rolling process. Several pilot programs have been implemented to explore the causes. In this theme, the most significant pilot programs, as well as the evaluation of their results will be presented.
