Abstract: The φ140~170 mm bars of steel 37CrMnMo(0.35~0.38C,0.85~1.00Mn,0.90~1.20Cr,0.28~ 0.33Mo,≤0.015P,≤0.008S)for coupling sleeve of petroleum drill stem are produced by 50t EBT arc furnace-LF (VD)-Al and Ca-Si wire feeding-3.16 t ingot casting-800/650×4 mills rolling flow sheet at Benxi steel. Analyais and examination results showed that hydrogen content in steel products was (0.5~1)×10-6,oxygen content(8~20)×10-6,nitrogen content(55~90)×10-6,inclusion rating 0~2, J25 hardenability HRC value 42~51, transversal impact energy at - 10℃ 56~218J, longitudinal impact energy at - 10℃ 76~233 J and the strength and plasticity of products all met the requirement of standard.
