摘要

试验Cr22Mo钢200 mm铸坯1150℃ 150 min加热经7道次粗轧7道次精轧成4.0 mm热轧卷

经980~1030℃退火和冷轧成0.8 mm板

并经950~1 020℃退火。试验研究了终轧温度850℃和800℃对Cr22Mo钢显微组织、织构及成形性的影响。试验结果表明

降低终轧温度

冷轧板的组织细化、再结晶织构强度增加、平均塑性应变比r值增加、平面各向异性△r值降低

降低终轧温度可显著改善冷轧板的成形性能。

Abstract

The tested steel Cr22Mo 200 mm cast slab is heated at 1 150 °C for 150 min

hot-rough-rolled with 7 passes- finishing rolled with 7 passes to 4. 0 mm hot-rolled coil

annealed at 980 ~ 1 030 °C and cold-rolled to 0. 8 mm sheet and annealed at 950 〜1 020 °C. The effect of finishing rolling temperature 850 °C and 800 on structure

texture and formability of steel Cr22Mo has been tested and studied. Experimental results show that with decreasing finishing rolling temperature the structure of cold-rolled sheet fines

the recrystallized texture increases

the average plastic strain ratio r value increases and the plane anisotropy Ar value decreases

therefore the formability of cold-rolled sheet markedly improves by decreasing finishing rolling temperature.
