Development of Steel Plates by Intensive Use of TMCP and Direct Quenching Processes

摘要

Historical progress of Thermo-Mechanical Processing (TMP) in steels during a last half century is briefly reviewed in the first part of this paper. On-line accelerated cooling process in wide plate mill was devel- oped by a Japanese steel mill in the end of 1970's, and its equipment was installed into major steel plate mills in Japan and Europe in 1980's.
