摘要/Abstract

摘要： 通过1700 mm热连轧机组对轮辐钢(%:0.09C、0.12Si、0.98Mn、0.010P、0.005S、0.010Nb、0.04Als)进行830～890℃终轧温度和620～680℃卷取温度的轧制试验。结果表明,板坯加热温度1230～1250℃、终轧温度(870±15)℃、卷取温度(660±15)℃生产的车轮用轮辐钢板的组织为细铁素体加少量的珠光体,屈服强度335～380 MPa,抗拉强度430～485 MPa,伸长率26%～31%,每卷带钢的纵向强度差为13～37 MPa,在车轮制作过程中冲压成型良好,冲废率小于0.3%。

Abstract: Rolling test on steel plate(0.09C,0. 12Si,0.98Mn,0.010P,0.005S,0.010Nb,0.04Als)for wheel spoke with finishing rolling temperature 830～890 ℃ and coiling temperature 620～680 ℃ has been carried out by 1700mm hot rolling mill train. Results showed that with slab heating temperature 1230~1250 ℃,finishing rolling tem- perature 870±15℃,coiling temperature 660±15 ℃,the structure of steel plate for wheel spoke was fine ferrite + minor pearlite,the yield strength of steel was 335～380MPa,tensile strength 430～485MPa,elongation 26%~31%,the longitudinal strength difference of each steel coil was 13~37MPa,and the punching formability during vehicle wheel manufacturing was excellent with punching rejection rate less than 0.3%.
