| Abstract: | Ti-bearing Al-killed steel always present an inferior castability, and a serious nozzle clogging. In this present paper, the research status on about Ti-bearing Al-killed steel was discussed synthetically, feature and behaviors orAl or Ti deoxidation was analyzed. The effect of different deoxidation technology and reoxidation of steel on the inclusions characteristics was summarized, reasons and some preventive measures of nozzle clogging were analyzed, which will be provided some ideas to improve the castability and quality of Ti-bearing Al-killed steel. |
