Ribbed bar for construction has an important ratio in the steel production of China,and a higher requirement of production quality has been put forward with the rapid development of economy.In this paper,the microstructure and mechanical properties have been studied and analyzed for HRBF400 fine grain ribbed bar produced with ultra fast cooling techniques,the results show that the strength of ribbed bar can be improved obviously with this technique and has a less degree of decrease in its plastic index.The fine ferrite and pearlite were obtained in the meantime and all kinds of properties can meet the request of national standard.
