【摘要】 针对我国生产的冷轧带肋钢筋塑性指标偏低问题,提出将冷轧变形程度控制在20%左右,即可使塑性、强度指标处于最佳组合区。据此,研制了新型建筑钢筋——冷轧三角螺旋钢筋,该钢筋强度可提高40%~60%,伸长率达6%~8%,且适于较大规格钢筋生产,使用此种钢筋可节约建筑钢材20%~30%。更多还原

【Abstract】 In view of the problem of low plastic indexes of cold rolled ribbed bar in China, it pointed out that the draught of cold rolling can be controlled at 20%,and best plastic and strength indexes can be obtained. Therefore,a new type cold rolled triangular spiral bar for construction was developed.The strength can be increased 40%～60% and elongation increased 6%～8% of this bar.Othermore,there is benefit to produce large gauge of this bar and can save material from 20% to 30%.更多还原
