摘要
为满足超细晶钢、双相钢(DP)、相变诱导塑性钢(TRIP)、无间隔原子钢(IF)等钢种的应用要求,近年来发展了换热效率高,使钢板和条钢短时间大幅降温的≥150℃/s超快速冷却技术,实现钢的细晶强化和相变强化。介绍了超快速冷却技术的原理,在轧制线上的布置,适用的钢种以及在国内外钢铁企业的应用。
In recent years, in order to meet the application requirement of specialty steel grades such as ultra fine grain steel, dual phase steel （DP）, transformation induce plasticity steel （TRIP） and interstitial free atom steel （IF）, the 〉~ 150 ~C/s ultra fast cooling technology with high efficiency of heat exchange, temperature drop of steel plate and long products in short time by a big margin has been developed to realize steel strengthening by fine grain size and phase trans- formation. The principle of ultra fast cooling technology, the layout of cooling system in rolling production line, the specialty steel grades being applicable and the application in steel works at home and abroad are presented in this article.
