The importance of initial solidification of molten steel in the mold has been widely acknowledged,as it is the origin of shell growth and determines both surface and internal quality of the final slab.However,most research regarding to initial solidification has been conducted in a way of mathematical simulation due to the high transient nature of thermodynamics and fluid flow in the upper mold.Through the recent developed mold simulator technology,the initial solidification behavior of Sn-Pb alloy was first successfully conduced in this paper,to allow the clear understanding of the inter-relationship between complex memscus heat transfer,casting surface oscillation marks and the in-mold temperature distribution.Heat flux across the mold was calculated by IHCP,and was then subjected to further PSD analysis.

碳对钢的力学性能影响很大，是钢中最重要的合金元素之一，脱碳就成为炼钢过程中最重要的反应之一.对AOD法的熔池混合和脱碳过程进行了模拟试验研究,在其他条件一定的情况下,考察了AOD炉侧吹喷枪的气量、夹角变化对均混时间、脱碳速率的影响.试验结果表明,吹炼过程中熔池液体处于充分的搅拌和循环运动状态,熔池内没有明显的死区,混合效果好,混合时间短.侧吹主枪的吹气量对熔池内流体的流动和混合有决定性的影响,侧吹
对DC03钢在中间包长水口和浸入式水口,铸坯的边缘、1/4处和中心处分别取样,用SEM-EDS观察钢中夹杂物,在浸入式水口、铸坯中特别是铸坯中心处观察到大量外面包裹一层碳化物、中心为钙铝酸盐的双层夹杂物,将这类夹杂物称之为碳化夹杂物或者石墨化夹杂物.通过面扫描和线扫描发现碳化物两种结构：一种为CaC2,另一种为铁碳化合物（渗碳体和石墨）.从热力学上分析了碳化夹杂物形成的条件,由于钢中碳为易偏析元素
