摘要
热轧钢筋是主要建筑用钢之一.我国同世界主要工业国家的钢筋应用水平相比还有较大差距.本文简要叙述了我国热轧钢筋半个多世纪的发展历程;阐述了三个主要级别HRB335、HRB400以及HRB500钢筋的生产现状;指出了我国热轧钢筋在品种质量和工艺技术水平上有了长足进步.目前,我国处于推广应用HRB400Ⅲ级钢筋的重要时期,进一步优化HRB400生产工艺、提高钢筋性能质量具有重要的意义.
Hot-rolled reinforced bar is one of the important construction steel grades. However, China lags behind the main developed industrial countries at rebar＇s production and applications. In the present paper, development of hot-rolled bar for more than half of century in China is briefly described before going into the main three hot-roiled ribbed bars of HRB335, HRB400 and HRB500. It has been also pointed out that hot-roiled bar in China has made a great progress in technology, quality and properties. At present, it is a crucial period of applying HRB400 for updating construction steel, so that to optimize HRB400 processes is very meaningful.
