摘　　要：采用超快冷工艺生产厚规格高强度H型钢,翼缘表面产生粒状或板条状贝氏体,使相变强化在H型钢中起着非常重要的作用,心部位置的晶粒更细小,同时带状组织的级别有效降低,有效提高H型钢的强度和韧性。The TMCP is used to produce thick high-strength H-beam steel.Granular or strip bainite is produced on the flange surface,so that phase transformation strengthening plays a very important role in H-beam steel.The grain at the core is smaller,and the grade of ribbon structure is effectively reduced,which effectively improves the strength and toughness of H-beam steel.

关 键 词：超快冷工艺 贝氏体 相变强化
