Slag without FeOx shows poor wettability on graphite due to absence of strong chemical reactions
FeOx reduction enriches Fe at interface, enhancing slag-graphite wetting
Coke exhibits better wettability than graphite
Coke has more pores allowing slag to penetrate surface gaps within certain surface tension range
