The experiment discussed in this paper was carried out at different reduction, different rolling temperature and annealing temperature with lubrication, after that deep drawability was measured, and the influence of the parameters of α-region hot rolling and annea- ling was analysed also. It is proved by the test that r is higher in two- time cold rolling than in one-time cold rolling at the same total reduction ratio. If total reduction ratio is fixed, r- values is higher when the second reduction ratio of cold rolling is larger than first. ODF was used in the analysis of textures, which is compatible with test.Key word：IF steel hot rolling reduction drawability r value1 前言IF 钢的轧制工艺参数对深冲性能的阻碍，是制定轧制工艺制度的重要依据。塑性应变比 r 值是反映深冲性能的指标，r 值越高其深冲性能越好。热轧采纳铁素体区轧制、冷轧合理确定...
