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%。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 1 230 ～ 1 250 ℃, finishing rolling temperature 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 manufac- turing was excellent with punching rejection rate less than 0. 3%.
