| Abstract: | This paper discusses the effect of rare earth element on formability of cold-rolling deep drawing steel under the test conditions of industrial production.It indicates that the cold-rolling coils treated by rare earth steel have good formability.Its value is higher than those without rare earth,and n value is equivalence.Rare earth element can improve the drawing-bulging and flanging in steel forming process.The micro-structures are ferrites and free cementite.Rare earth element adding inclusions of spheroidizing steel can improve anisotropy of steel. |
