【Abstract】 In order to explore the relationship of the process parameters of the strip continuous annealing with acceleration and the galvanized strip recrystallization,based on the TTT diagram measurements of the galvanized ST01Z steel,the recrystallization kinetics of the strip continuous annealing with acceleration was studied in this paper.The CHT(continuous heating transformation)diagram and its computing program of the gavanized ST01Z strip for the continuous annealing processes with acceleration,which temperature field calculated by finite difference method,were gained.The developed program has been used in practice,and the production or the strip speed was increaswed more than 10%.更多还原
