摘要
为了提高抗震钢筋HRB500E的强度与屈强比，保证其抗震性能，针对攀成钢棒、线材机组生产实际条件，采用不同微合金化方式，不同轧后冷却工艺，进行了HRB500E高强抗震钢筋生产实践。高线机组生产D6—12mm规格钢筋时，采用钒氮微合金化，添加0．08％-0．11％的V，V／N接近4：1，轧后斯太尔摩风冷工艺；棒材机组生产D14～40mm钢筋时，采用钒氮＋钼复合微合金化，添加0．06％～0．12％的V，V／N接近4：1，0．03％-0．05％的Mo，轧后自然冷却。结果表明：生产的HRB500E获得了高的强度和良好的抗震性能，相关指标满足国家标准和用户的要求。
In order to increase the strength and yield strength-to-tensile strength ratio of the aseismatic rebar, high-strength aseismatic rebar HRBS00E was produced by employing different microalloying way and cooling process after rolling according to practical production conditions of bar and wire rod units in Pan- gang Group Chengdu Steel ＆ Vanadium Co. Ltd. When 0 6 - 12 mm HRB500E was produced by high speed wire mill, the steel was micro-alloyed by VN and Stelmor wind cooling process was adopted. After 0.08%-0. II% of Vwas added to the steel, V to N ratio was close to 4：1. When 0 14-40 mm HRBS00E was produced by bar mill, the steel was micro-alloyed by VN ＋ Mo, and natural cooling was a- dopted. 0.06% -0.12% V and 0.03% -0.05% Mo were added to the steel, and V to N ratio was close to 4：1 after the addtion. The results show that the rebar HRB500E so produced is of high strength and good anti-seismic properties, and satisfies the national standards and client requirements.
