cold rolling and double cold rolling were applied to hot rolled strips with different reduction ratios. The evolutions of {100},{111} and Goss face texture during double rolling were investigated by comparing the orientation distribution function(ODF) of the double rolled sample with that of the single rolled one. The double cold rolling texture is characterized by a higher γ-texture and a lower α......
冷连轧轧制力计算模型及改进方案王飞1(1.河北省唐山市首钢京唐钢铁联合有限责任公司第一冷轧厂 )摘 要:过程控制系统要求数学模型能正确反映规律性,运算简单,并且有较高的预报精度.轧制力计算模型是过程控制数学模型的核心,轧制力的计算精度直接影响到板形与板厚控制的精度.为了提高轧制力计算的精度,通过对冷轧轧制力特点的分析和计算模型的研究,我们在现有Hill公式的基础上,考虑张力对计算冷轧带钢轧制力的影响并借助于自学习计算功能,通过添加张力影响因子和模型自学习系数对Hill公式进行了改进,在保证轧制力预报精度的同时实......

on dislocation lines, while there still exists small spheric G.P zone in the region with less dislocation. In addition the precipitates in 7A04 alloy with cold rolling present more obvious tendency of growth and coarsening than those without cold rolling. It is indicated that the coherent strain energy of the cylinder formed G.P zones with matrix in the 2024 alloy is smaller than......
