[0029] The preparation method of vanadium-containing TAM steel includes the following steps:
[0030] a. Mechanical rolling process: the steel billet is smelted and cast into a slab, heated at 1150~1250℃ for 70~90min, then hot rolled into a 3~5mm thick hot rolled steel plate, and then cold rolled to 1~ 1.5mm, the cold rolling reduction ratio is 65-75%, and the ferrite + pearlite structure is obtained; among them, the finishing temperature of hot rolling is 750-850℃, and the coiling temperature is 650-700℃;
[0031] b. Q&P process: The cold-rolled sheet obtained in step a is first heated to austenitizing temperature of 900-920°C at 10°C / s, held for 600s, and then cooled to room temperature at 50°C / s; then at 10°C / s s Reheat it to the annealing temperature of 760-850℃, keep it for 600s, then reduce the temperature at 50℃ / s to the distribution temperature of 150-450℃, keep it for 50-200s, and finally reduce the temperature to room temperature at 50℃ / s to get it.
