Wetting behavior of CaO–Al2O3-based mold flux with various BaO and MgO contents on the steel substrate
文献摘要：
The interfacial phenomena in mold have a great impact on the smooth operation of continuous casting process and the quality of the casting product. In this paper, the wetting behavior of CaO–Al2O3-based mold flux with different BaO and MgO contents was studied. The res-ults showed that the contact angle between molten flux and interstitial free (IF) steel substrate increased from 62.4° to 74.5° with the increase of BaO content from 3wt％ to 7wt％, while it decreased from 62.4° to 51.3° with the increase of MgO content from 3wt％ to 7wt％. The interfa-cial tension also increased from 1630.3 to 1740.8 mN/m when the BaO content increased, but it reduced from 1630.3 to 1539.7 mN/m with the addition of MgO. The changes of contact angle and interfacial tension were mainly due to the fact that the bridging oxygen (O0) at the interface was broken into non-bridging oxygen (O?) and free oxygen (O2?) by MgO. However, more O? and O2? connected into O0 when BaO was ad-ded, since the charge compensation effect of BaO was so stronger that it offset the effect of providing O2?.
