摘　　要：本文介绍了ＨＲＢ４００ＭＰａ级新Ⅲ级钢筋的工业性生产技术。工业性试制结果表明：在原２０ＭｕＳｉⅡ级钢筋的基础上修改冶炼和轧钢生产工艺，并添加微合金元素Ｖ，能够有效提高钢筋的强度，满足４００ＭＰａ级钢筋性能要求。钢中每添加０．０１％的Ｖ，其屈服强度将提高８～１２ＭＰａ，抗拉强度将提高７～１０ＭＰａ。This paper briefy introduced the industrial production technique of new three class rebar of HBR 400MPa class. The result of inductrical trial f manufacture states that through improving smelting and rolling process and adding micro alloting of V the strength of rebar can be increased based on old HRB 335MPa class rebar,within the limites of 0.075-0.015 if once adding 0.01 % V the yield strength of this rebar can be enhanced 8-12MPa and the resistance to stretch strength can be enhanced about 7-10MPa.
