针对钢板不同情况分别测试了本钢和浦相钢板的表面、1/4、1/2厚度处织构,并通过晶粒度、n值、r值的比较得出两块钢板存在质量差异。优良的深冲性能要求钢板的各个不同层面上,不仅要以{111}织构为主,而且要求{111}织构分布集中。 According to the different conditions of the steel plate, the surface of the steel and the P phase plate, the texture at 1/4 and 1/2 thickness were tested, and the quality difference of the two plates was obtained by comparing the grain size, n value and r value. Good deep-drawn properties require that the various layers of the steel not only be dominated by the {111} texture, but also require the {111} texture to be concentrated.
