摘要： 釆用Al₂Q₃溶解速率测定仪测定了 CaO-SiO₂-Na₂O-CaF₂-Al₂O₃-MgO连铸保护渣系的抱@溶解速率。通过建立Al₂O₃溶解速率和渣成分关系的回归正交设计模型，精确预测铝镇静钢连铸保护渣的夹杂物吸收能力，并通过建立的非线性规划模型对该保护渣进行优化设计。结果表明，在CaO/SiQ = 1.15,Na₂CO₃0.0%,CaF₂ 20.0%,2.0%, MgO 8.0%时，连铸保护渣的溶解速率的最大值为1.73 x 10^-3 kg·m^-2 ·s^-1

Abstract: Hie Al₂O₃ dissolution rate of casting mold powder CaO-SiO₂-Na₂O-CaFi-Al₂O₃-MgO series has been measured by dissolution rate measuring apparatus. Hie inclusion absorption ability of mold powder for Al-killed steels could be predicted accurately by established regression analysis model for relation between Q dissolution rate and mold powder ingredient, and the mold powder for Al-killed steels has been optimized and designed by established nonlinear programming model. Hie results showed that with CaO/SiOz = 1.15, Na₂CO₃ 20.0%, CaF₂ 20.0%, Al₂0₃ 2.0%, MgO 8.0%, the Al₂0₃-2 ·s^-1
