Embodiment 1
[0032] The chemical composition and percentage of HRB600E vanadium-containing high-strength hot-rolled anti-seismic steel bars are shown in Table 1, and the performance parameters are shown in Table 2.
[0033] The process flow is as follows:
[0034] (1) Smelting: Decarburization and dephosphorization of molten iron together with scrap steel and slagging materials, etc., the end point carbon is 0.10%, the end point phosphorus is 0.014%, the end point temperature is controlled at 1650°C, and ferromanganese nitride and silicon are added during the tapping process Iron, silicon-manganese alloy and vanadium-nitrogen alloy are alloyed with manganese, silicon and vanadium, and argon is blown and stirred throughout the tapping process.
[0035] (2) Refining outside the furnace: the molten steel in step (1) is sent to the LF furnace for refining, and the temperature and composition of the molten steel are finely controlled. The whole process of refining is argon blowing and stirring ...

Embodiment 3
[0048] The chemical composition and percentage of HRB600E vanadium-containing high-strength hot-rolled anti-seismic steel bars are shown in Table 1, and the performance parameters are shown in Table 2.
[0049] The process flow is as follows:
[0050] (1) Smelting: Decarburization and dephosphorization of molten iron together with scrap steel and slag-forming materials are carried out. The end point carbon is 0.14%, the end point phosphorus is 0.015%, and the end point temperature is controlled at 1670°C. Ferromanganese nitride and silicon are added during the tapping process. Iron, silicon-manganese alloy and vanadium-nitrogen alloy are alloyed with manganese, silicon and vanadium, and argon is blown and stirred throughout the tapping process.
[0051] (2) Refining outside the furnace: the molten steel in step (1) is sent to the LF furnace for refining, and the temperature and composition of the molten steel are finely controlled. The whole process of refining is argon blowin...
