| 摘 要： | 应用共存理论和规划理论,以夹杂物与钢水化学反应自由能变化值最小化为目标,建立了夹杂物成分与结晶器钢水成分之间关系的数学模型.经验证,在夹杂物为液态的情况下,模型计算结果与实测结果相符合.利用模型计算了Ca]、Al]含量对夹杂物成分的影响.结果表明,为将CaO-SiO2-Al2O3系夹杂物控制在塑性区,结晶器中钢水Al]含量应根据Ca]含量的变化而变化.当Ca]的质量分数为5×10-6时,应控制钢水中Al]的质量分数在12×10-6左右. |

| Abstract: | Based on the coexistence theory of steel slag structure and the programming theory, a mathematical model revealing the relationship between inclusions and molten steel composition in a continuous casting mold was developed with the aim to minimize the free energy change of the reaction between inclusions and liquid steel. It is verified by the experiment that results calculated with the model are agreement with the experimental ones well when the inclusions are in liquid state. The effects of Ca] and Al] ... |
