摘要
概述了中国建筑用带肋钢筋、线材品种的现状及其发展趋势,介绍了余热处理钢筋、超细晶热轧钢筋、多种微合金化方法试制的HRB400钢筋、HRB500钢筋5、90 MPa级热轧钢筋、800 MPa以上级高强度钢筋、高碳钢盘条、建筑标准件用冷镦钢盘条等应关注和发展的建筑用钢品种,并就如何促进我国建筑用带肋钢筋、线材品种的优化和更新换代提出了建议。
In this paper,the present situations and developing trends of ribbed bars and wires for the buildings in China are summarized.Bars by remained heat treated,ultra-fine grain reinforcing steel bars,HRB400 bars produced by different microalloying techniques,HRB500 bars,590 MPa grade bars,800 MPa grade or greater high intensity bars,high carbon wires and cold forging steel wires for the buildings,etc are introduced.We put forward proposals how to promote variety optimization of ribbed bars and wires for the buildings in China and how to replace the older generations of products by new ones.
