Description

<p>Wettability between molten iron and non-metallic inclusions is an important factor, as it influences the behavior of non-metallic inclusions during secondary metallurgy. In the present study, the wettability of CaS against molten iron was investigated using the sessile drop method at 1873 K. The CaS substrate was fabricated using spark plasma sintering, achieving a high relative density of 98%. The measured contact angle of CaS against molten iron was found to be 118 degrees. This finding indicates that the wettability of CaS is poor, which contrasts with the previous report. This result will contribute to further understanding regarding the inclusions’ behavior during secondary refining processes.</p>
