摘要

垂直离心铸造可以显著提高熔融金属的填充能力,使生产复杂的薄壁铸件在接近快速的冷却速度。本文对垂直离心铸造80mm × 60mm × 2.5 mm的316l钢铸钢带在不同转速下的熔体流动、凝固组织和缺陷进行了数值和实验分析。随着转速从150 r/min逐渐增加到900 r/min,模拟结果表明,转速为600 r/min时铸带的充型时间最短,气孔体积最小。由于型腔旋转在充型过程中会产生强烈的湍流,实验结果表明,在离心力作用下,316 L铸带形成“非枝晶”结构,而参考样品在不旋转的情况下则形成典型的枝晶结构。铸带的大部分区域为一维冷却,但铸带的一侧出现三面冷却。利用计算机断层扫描技术对316l带材的气孔和裂纹进行了检测,并进行了数值模拟分析。结果表明,存在一个使铸带缺陷最小的最佳转速。本研究对垂直离心铸造带材的充型和凝固过程有了更好的了解。

Melt flow, solidification structures, and defects in 316 L steel strips produced by vertical centrifugal casting

Vertical centrifugal casting can significantly enhance the filling capability of molten metals, enabling the production of complex thin-walled castings at near-rapid cooling rates. In this study, the melt flow, solidification structures, and defects in 316 L steel cast strips with a geometry of 80 mm × 60 mm × 2.5 mm produced by vertical centrifugal casting were numerically and experimentally analyzed under different rotation speeds. With gradually increasing the rotation speed from 150 r/min to 900 r/min, the simulated results showed the shortest filling time and minimum porosity volume in the cast strip at a rotation speed of 600 r/min. Since a strong turbulent flow was generated by the rotation of the mold cavity during the filling process, experimental results showed that a “non-dendritic” structure was obtained in 316 L cast strip when centrifugal force was involved, whereas the typical dendritic structure was observed in the reference sample without rotation. Most areas of the cast strip exhibited one-dimensional cooling, but three-sided cooling appeared near the side of the cast strip. Moreover, the pores and cracks in the 316 L strips were detected by computed tomography scanning and analyzed with the corresponding numerical simulations. Results indicated the existence of an optimal rotational speed for producing cast strips with minimal casting defects. This study provides a better understanding of the filling and solidification processes of strips produced by vertical centrifugal casting.
