Considering the existing equipment available in the steelmaking and rolling plants of Honghe Iron and Steel Co.,Ltd.,HRB500E high strength anti-seismic rebars were developed by microalloying,controlled rolling and controlled cooling process and mechanical properties,microstructures,inclusions of rebars so produced were tested by tensile testing machine and metallographic microscopy.The results showed that the rebars exhibited moderate strength ＆ toughness,good anti-seismic performance and low strain aging;Besides,they boosted preferable comprehensive performance,featuring a final temperature after controlled cooling greater than 680 ℃,Mn content less than 1.55%,Nb content less than 0.025%,and core microstructure of ferrite + pearlite +5% bainite.
