一、前言世界宽带钢轧制生产比例的稳步增长,充分证明控制和改进带钢质量具有极其重要的意义。本文叙述现代无损检测系统的发展趋势及其对热轧、冷轧带钢质量的积极作用等两方面,讨论了为在德国多特蒙德赫施钢铁公司热轧宽带钢和冷轧带钢轧机上进行试验而开发的几种系统。 I. Preface The steady growth of the world wide strip rolling production ratio has proved that it is extremely important to control and improve the strip quality. This article describes the development trend of modern non-destructive testing systems and their positive effects on the quality of hot-rolled and cold-rolled strip steel. It is discussed that a test is to be carried out on hot-rolled wide strip and cold-rolled strip mills in Dortmund, Germany, The development of several systems.
