结晶器保护渣润滑能力(Therefore, the amount of powder consumed per unit of surface area(kg/m²) is most suitable for evaluating the lubrication capability of mold fluxes. 因此，采用单位表面积保护渣消耗量 (kg/m²) 最适合评价结晶器保护渣的润滑能力。)
铸坯/结晶器界面的润滑(A molten flux layer remains against the strand shell, which ensures the lubrication of the strand/ mold interface. 液态保护渣层紧挨铸坯壳，它确保了铸坯/结晶器界面的润滑。)
