根据某H型钢生产厂的实际生产数据，建立终轧产品为 H200×200×12×8的热连轧模型。利用有限元软件ANSYS -LSDYNA对热连轧过程进行数值模拟。根据模拟结果，分析金属流动规律和变形规律。由于腹板和翼缘在不同的变形区内进行变形，H型钢的变形过程较为复杂，腹板与翼缘连接处金属变形尤为复杂。腹板和翼缘的金属由于延伸率不同而导致腹板和翼缘的金属之间进行相互交换。研究 H型钢腹板和翼缘的金属流动和变形与延伸率、轧制速度、摩擦系数等因素之间的影响规律，为制定合理的轧制规程，提高产品质量提供依据。

According to the production data of a rolling H -beam factory ,the FE model of hot continuous rolling process of H -beam is built .With the FEM software of DEFORM -3D ,the continuous rolling of H -beam was simulated .On base of simulation result ,the metal flow and deformation law are discussed . Because of the flange and web is deformed in the different deformation zone ,the metal flow law of flange and web is complex ,especially the metal of the conjunction of flange and web .The exchange of metal be-tween the flange and the web of H -beam alters to the different elongation ratio of flange and web .The other factors w hich influents on the metal flow ,are taken into consideration ,such as rolling speed and friction coefficient .By adjustment to the rolling parameters ,the defect of the H -beam is reduced .
