前言一提到薄板的成形性,就想起Erichsen试验或德国式的深拉延性试验等等,其历史可追朔很远。令人注目的是这个问题的提出差不多与带钢轧机的运用处于同一时期。随后,虽然在第二次世界大战中也有一些研究,但广泛的大张其鼓地进行研究,无论是在日本还是在世界各国,都还是最近的事情。就以薄钢板为例,用带钢轧机进行大规模生产和以汽车业为首的各行业大量用薄钢板进
Mentioned in the foreword The formability of the sheet, reminiscent of the Erichsen test or German-type deep ductility test, etc., the history can be traced far. What is striking is that this issue is presented almost at the same time as the operation of strip mills. Subsequently, although there were some studies during the Second World War, extensive research conducted in a big way was still the most recent event in Japan and other countries in the world. Take the thin steel plate as an example, large-scale production is carried out by strip rolling mills and a large number of thin steel plates are used in various industries led by the automobile industry
