摘　　要：首钢采用SUFC工艺试制了大规格(Φ40mm)棒材,本文通过实验确定了变形工艺参数,测定了试样的CCT曲线,并对棒材断面的径向温度场进行了模拟,分析了试样组织。工业生产表明,柔性控轧+SUFC+自回火工艺大幅提高了材料的强度,且生产成本较低。The large-sized bar（Φ40mm） was trial-produced by surface ultra-fast cooling process in Shougang. The formation process parameters were confirmed and the CCT curves were measured by experiments. The cross-section temperature field of the bar section was simulated. Meanwhile, the structure of the samples was analyzed. The production practice show that flexible controlled rolling ＋ surface ultra-fast cooling ＋ self tem- pering process can increase strength greatly with low cost.
