Examples
Embodiment 1
[0079] Example 1: The billet is heated to 1180°C, the holding time is 2h, the rough rolling start temperature is 1200°C, after 3 passes of rough rolling, the rough rolling finish rolling temperature is 1035°C, the finishing rolling start temperature is 1000°C, The final rolling temperature of finish rolling is 885°C. After 5 passes of finish rolling, the thickness of the steel plate is rolled to 40mm; the steel plate is laminarly cooled to 390°C at a cooling rate of 18°C / s, and then air-cooled to room temperature; Insulate at 700°C for 0.5h, laminarly cool the steel plate to 405°C at a cooling rate of 18°C / s, and then air cool to room temperature.
Embodiment 2
[0080] Example 2: The billet is heated to 1200°C, the holding time is 2h, the rough rolling start temperature is 1200°C, after 3 passes of rough rolling, the rough rolling finish rolling temperature is 1055°C, the finish rolling start rolling temperature is 995°C, The final rolling temperature of finish rolling is 860°C. After 6 passes of finish rolling, the thickness of the steel plate is rolled to 25mm; the steel plate is laminarly cooled to 364°C at a cooling rate of 15°C / s, and then air-cooled to room temperature; Insulate at 680°C for 1.5h, laminarly cool the steel plate to 420°C at a cooling rate of 18°C / s, and then air cool to room temperature.
Embodiment 3
[0081] Example 3: The billet is heated to 1200°C, the holding time is 2h, the rough rolling start temperature is 1200°C, after 4 passes of rough rolling, the rough rolling finish rolling temperature is 1070°C, the finishing rolling start temperature is 1010°C, The final rolling temperature of finish rolling is 901°C. After 6 passes of finish rolling, the thickness of the steel plate is rolled to 12mm; the steel plate is laminarly cooled to 395°C at a cooling rate of 20°C / s, and then air-cooled to room temperature; Insulate at 660°C for 3 hours, laminarly cool the steel plate to 435°C at a cooling rate of 15°C / s, and then air cool to room temperature.
