用取向分布函数（ＯＤＦ）方法对造成ＩＦ钢板与ＳＰＣＥ钢板ｒ差异的织构因素进行了分析。结果指出，由于铁素体中间隙原子存在状态不同经冷轧后冷轧织构不同，进而经退火后退火织构不同，ＩＦ钢的退火织构以｛１１１｝＜１１０＞、｛１１１｝＜１１２＞织构为主，ＳＰＣＥ钢的退火织构以｛００１｝＜１１０＞织构为主。｛１１１｝取向晶粒的ｒ大于｛００１｝取向晶粒的ｒ值，因而超深冲ＩＦ钢有比深冲ＳＰＣＥ钢板高的ｒ值。
The texture factor that caused the difference between the IF steel plate and the SPCE steel plate was analyzed by the orientation distribution function (ODF) method. The results show that due to the existence of different interstitials in the ferrite, the cold-rolled cold-rolled texture is different and the annealed texture is different after annealed. The annealed texture of IF steel consists of {111} <110>, {111} < 112> texture. The annealed texture of SPCE steel is dominated by {001} <110> texture. The r of the {111} oriented grains is greater than the r value of the {001} oriented grains so that the ultra-deep-drawn IF steel has a higher r value than the deep-drawn SPCE steel.
