摘　　要：在铌钒复合微合金化的条件下,通过轧后控冷工艺调整钢筋上冷床温度,研究了控冷工艺对600MPa级抗震钢筋的金相显微组织与力学性能的影响。检验结果表明:轧后控冷最佳上冷床温度为860℃,该控冷工艺下批量生产的600MPa级高强抗震钢筋性能均符合标准要求。In this study, under the condition of Nb-V micro-alloying, the temperature of the cooling bed on the rein- forcement was adjusted by the controlled cooling process after rolling, The results of metallographic microstructure and mechanical property test showed that the optimum upper cooling bed temperature after rolling is 860 ℃. The perform- ance of the 600MPa grade high-strength seismic reinforcement produced in batch under the controlled cooling process met the standard requirements.
