摘要: 统计得出126卷SUS410L钢(/%:0.02C,0.98Si,0.99Mn,0.018P,0.022S,12.44Cr,0.025N)3 mm热轧带卷退火后(板温840℃,过线速度50 m/min)的力学性能波动较大(抗拉强度551~673 MPa,伸长率16%~28%),在连续冷轧时易引起断带事故。在退火时通过合理的引带长度和将TV值(带钢厚度×过线速度)由150降至120(过线速度40 m/min)时,使力学性能波动较小(抗拉强度593~639 MPa,伸长率20%~22%),有利于冷轧顺利进行。

Abstract: It is obtained by statistics that the fluctuation of mechanical properties of annealed 126 coils 3 mm hot- rolled steel SUS410L (/%: 0.02C, 0.98Si, 0.99Mn, 0.018P, 0.022S, 12.44Cr, 0.025N) strip annealed with strip temperature 840 °C. and strip-line running speed 50 m/min is larger, that is tensile strength 551-673 MPa and elongation 16%-28% , caused the strip breaking accident during continuous cold-rolling process. During annealing by using reasonable leading strip length and decreasing the TV value (thickness of strip x strip-line running speed) from 150 to 120 (strip- line running speed 40 m/min) , the fluctuation of strip mechanical properties is smaller, that is tensile strength 593-639 MPa and elongation 20%-22% , it is available to carry out the cold-rolling process.
