In the paper, the effects of reheating temperature in the on-line normalizing process on yield strength and impact energy of steel tube were explored with industrial experiments based on the indexes of yield strength and impact toughness for Φ139.7 mm × 7.72 mm N80-1 casing in the Q/YS 1572.1 standard. The results showed that the yield strength of steel tube could reach 570~620 MPa and the half-size longitudinal impact energy at 0 ℃ is ≥40 J if the temperature of steel tube before entering reheating furnace was≤550 ℃ and reheating temperature was controlled at 870~900 ℃, which could meet the requirements of the Q/YS 1572.1 standard.
