Abstract: The recrystallized annealed structure and HB hardness of DDQ(Deep Drawable Quality)cold-rolled deep drawing sheet of0.003C-0.05Al-0.06Cu steel produced by TSCR(Thin Slab Casting and Rolling)process have been test- ed and researched. Results showed that the recrystallization temperature of the DDQ cold-rolled deep drawing sheet was ~550 ℃,and the available isothermal-annealing temperature was 650 ℃.

Key words: TSCR Process, DDQ Deep Drawing Sheet, Recrystallization Temperature, Isothermal Annealing

摘要： 试验研究了TSCR(Thin Slab Casting and Rolling)薄板坯连铸连轧工艺生产的(%)0.003C-0.05Al- 0.06Cu钢DDQ(Deep Drawable Quality)级深冲薄板的再结晶退火后的组织和HB硬度。结果表明,该钢DDQ级冷轧深冲薄板的再结晶温度为～550℃,合适的等温退火温度为650℃。
