摘要
文章介绍了在包钢2 250 mm热连轧生产线试制的22 mm X80管线钢热轧板卷的生产情况。通过采用低碳、高w[Mn+Nb]、w[Mo+Cr+Cu]的合金化成分设计,应用包钢纯净钢冶炼技术,差异化加热技术、恒速轧制技术和高效加密层流冷却控制技术,生产出具有针状铁素体的高强度高韧性X80管线钢热轧卷板。板卷的强度和韧性指标达到要求。
In the paper, it is introduced production status for hot rolled coil of 22 mm X80 pipeline steel which are trial produced in 2 250 mm hot rolling production line of Baotou Steel. High strength and toughness X80 pipeline steel hot rolled coil with acicular ferrite are produced by using the design of alloying composition of low carbon, high w [ Mn ＋ Nb] , w [Mo ＋ Cr ＋ Cu] , applying smelting technology of clean steel in Baotou Steel, heating technology of differentiation, con-stant speed rolling technology and cooling control technology of efficient encryption laminar flow. The strength and toughness index of the coil meets the requirements.
