摘要
目前在国际上普遍使用的是400 MPa等级以上建筑钢筋,我国将HRB400钢筋列为混凝土结构的主导钢筋,同时HRB钢筋已纳入GB1499.2-2007标准中,新钢公司在HRB400钢筋生产技术已相当成熟且生产具有一定规模的基础上,成功研制开发了Φ36 mm热轧HRB500 MPa钢筋,为公司做了必要的产品技术储备。
The 400MPa grade which has been widely used in the world is called construction steel bar, HRB400 steel bar has been defined the leading steel bar of concrete structure, listed in GB1499. 2 - 2007 standard. The production technology of HRB400 steel bar has been matured and has production scale at Xingang. On the basis, Ф36mm hot rolling HBR500 steel bar is successfully developed and the essential product technical reserves have been done for Xingang development.
