Abstract

Abstract: Since the nineties of 20 century the thin slab casting-direct rolling and the medium-heavy slab casting-Steckel Mill rolling technologies have been involved in production line of high strength low alloy(HSLA)steel,and in these processes a lot of available operation experiences of thermal-mechanical control process(TMCP)for production of HSLA steel have been achieved. At present the steel grades being developed by CSP(compact strip production)process are (1) ECC,UCC and IF soft steel;(2) high strength multi-phase DP and TRIP steel; and (3) X80 grade pipe steel. The characteristic and optimization of both processes for developing HSLA steel grade are presented.

摘要： 20世纪90年代以来,薄板坯连铸连轧技术及中厚板坯炉卷轧制工艺,进入了低合金高强度钢(HSLA)的生产流程;并在该流程中对HSLA钢热机械控制轧制工艺(TMCP)取得了不少有益的经验。目前薄板坯连铸连轧CSP(Compact Strip Production)工艺所开发的钢种有:(1)ECC、UCC和IF软钢;(2)高强度多相DP和TRIP钢;(3)X80级管线钢。介绍了薄板坯连铸连轧和中厚板坯炉卷轧制工艺开发的HSLA钢品种的工艺特点和工艺优化。
