Effect of Composition on Solidification Structure of Low Carbon Steel Based on CAFE Method
-
摘要: 钢的成分是影响铸坯凝固组织的重要因素, 在钢种标准成分范围内, 基于CAFE法对低碳钢Q235成分对凝固组织的影响进行研究分析。单一变化C、Si和Mn的含量, C含量的增加使得等轴晶率增加, C含量为0.22%时等轴晶率达到最大;当Si含量增加时, 等轴晶数量先增多, 之后又降低趋势;当Mn含量增加时, 组织中等轴晶数量呈下降趋势, 且Mn含量的变化对等轴晶数量的影响不大。Abstract: The composition of steel is an important factor affecting the solidification structure of slab.In this paper,the influence of the composition of low carbon steel Q235 on the solidification structure is studied based on the CAFE method. The increase of C content and the increase of C content make the equiaxed grain rate increase and the C content is 0. 22%. With the Si content increasing,the number of equiaxed grains increases firstly and then decreases The number of equiaxed grains in the structure decreases with the increase of Mn content,and the change of Mn content has little effect on the number of equiaxed grains.
