摘要
建筑结构的快速发展对建筑用钢材提出了越来越高的要求。特别是在汶川地震后,高强度、高性能抗震钢筋的生产开发成为国内外的研究热点。灾后重建及国家实施的基础设施建设的大量投入,都需要大批量的高强度抗震钢筋,适应建筑钢材升级换代的市场需求,提高螺纹钢产品的市场竞争力。在钢筋的生产中,普遍采用钒氮微合金化+控制轧制的方式来实现晶粒的细化,以获得良好的综合性能。
The rapid development of architectural structure of architectural steel put forward higher request.Especially in the wenchuan earthquake,high strength,high-performance reinforcement production development and become.The post-disaster reconstruction and implementation of state infrastructure construction,all need large quantities of high strength steel reinforcement,adapt to the construction of market demand,the upgrading of products to improve the market competitiveness,rebar in steel production,generally using vanadium nitride micro alloying ＋ control of grain refinement of realization way to obtain good performance.
