摘要
采用金相检测、透射电镜和能谱分析等方法,分析CSP产线屈服强度700MPa级别含Ti高强钢长度方向和宽度方向的温度波动影响钢卷中第二相TiC粒子的析出形貌和析出量,是造成含Ti高强钢强度波动的主要原因。通过调整卷取温度、卷后堆垛缓冷以及采取层冷边部遮挡等措施,得到了性能稳定均匀的高强钢。
A conclusion can be drawn that the precipitation texture and quantity of second phase particle of TiC,effected by the temperature fluctuation of length direction and width direction,in the Ti high-strength steel which yield strength was 700 MPa produced by the CSP process,was the primary cause of strength fluctuation of the Ti high-strength steel.Through the adjustment of coiling temperature,slow cooling of stacking,edge-masking of laminar cooling,the performance stability has been improved.
