經(jīng)過(guò)長(zhǎng)期技術(shù)攻關(guān)，多年前，河鋼唐鋼已具備采用常規(guī)板坯流程生產(chǎn)1500MPa級(jí)熱成型鋼的能力。但他們并沒(méi)有止步，今年5月起，他們決定采用薄板坯流程開(kāi)發(fā)2000MPa級(jí)熱成型鋼?！氨绕鸪Ｒ?guī)板坯流程，薄板坯流程具有生產(chǎn)周期短、能耗低的巨大成本優(yōu)勢(shì)?！崩顗?mèng)英說(shuō)。
然而世界上還沒(méi)有采用薄板坯流程開(kāi)發(fā)這種強(qiáng)度熱成型鋼的先例。為此，他們組織精干技術(shù)與生產(chǎn)力量，全面開(kāi)展自主研發(fā)和創(chuàng)新。在工藝流程設(shè)計(jì)、成分優(yōu)化與精準(zhǔn)控制、過(guò)程溫度匹配、連鑄保護(hù)渣優(yōu)化與工藝參數(shù)制定等方面不斷摸索試驗(yàn)，終于解決了薄板坯流程煉鋼、連鑄及薄規(guī)格軋制等關(guān)鍵性難題，成功實(shí)現(xiàn)了2000MPa級(jí)熱成型鋼的開(kāi)發(fā)。
