Because of interfacial and surface tension, micron-sized liquid oxide droplets are expected to change from spherical (when fully immersed in liquid steel) to lens shape on top of steel. Inclusion sizes were measured by automated analysis of polished sections of calcium-treated aluminum-killed steel. A sample of the same steel was remelted and observed using confocal scanning laser microscopy. Droplets on the steel surface appear to have approximately twice the diameter of fully immersed spherical inclusions.

透镜形状效应引起的液体夹杂物畸变：使用 HT-CSLM 对 LCAK 钢进行原位观察和量化

由于界面和表面张力，微米大小的液态氧化物液滴预计会从球形（完全浸入钢水时）变为钢顶部的透镜形状。夹杂物尺寸通过对钙处理的铝镇静钢的抛光部分进行自动分析来测量。对同一钢的样品进行重熔并使用共聚焦扫描激光显微镜进行观察。钢表面上的液滴似乎具有完全浸入的球形夹杂物直径的大约两倍。
