摘要
基于高强抗震钢筋的基本特征,介绍了微合金化、余热处理及细晶化技术在生产高强抗震钢筋中的应用。微合金化技术相对于其他两种应用更为广泛,余热处理和细晶化技术比微合金化成本低,无需添加合金元素,且能满足钢筋的抗震性能。通过对3种工艺的综合分析,提出在生产高强抗震钢筋时,应当将微合金化与余热处理结合起来,这样不仅节约生产成本,还有利于提高钢筋的抗震性能。
The application of the micro-alloying, quenched and self-tempered (QST) and fine-grained technolo- gies in high-strength aseismic reinforcement steel bars are introduced, based on characteristics of high-strength aseis- mic reinforcement steel bars. Micro-alloying technology is more widely used than the other. The cost of the QST and fine grained technology without adding alloying elements is lower than the micro-alloying and can also meet the seismic performance o{ steel bars. The compTehensive analysis of three processes shows combining micro-alloying with QST in the production of high-strength aseismic steel bars can reduce the production cost and improve the seismic perfor- mance.
