Embodiment 1 to Embodiment 5
[0069] Embodiment 1 to embodiment 5 provide a kind of aluminum-containing high-strength steel and its preparation method and application. The preparation method is as follows:
[0070] The slab obtained by continuous casting is placed in a heating furnace for heating. During heating, the temperature of the first stage of heating is 700-800°C, the temperature of the second stage of heating is 1150-1190°C, the temperature of the soaking section is 1190-1220°C, and the total heating time is 130-160 minutes, followed by two passes of rough rolling and finish rolling for descaling, finish rolling, ultra-fast cooling and coiling to obtain hot-rolled coils. Among them, the pressure of descaling water in the two passes of finishing rolling is 23MPa, and the ultra-fast cooling adopts laminar flow cooling front-end cooling mode,
[0071] Hot-rolled coils are pickled and cold-rolled, followed by continuous annealing to obtain high-strength steel. The cold rolling is 5 passes of continuo...
