amount of powder consumed per unit of surface area(Mold powder consumption has been expressed in different forms, such as kg/tonne of steel, kg/m2 and kg/minute. However, the consumption depends upon the size of the cast slab and is proportional to the surface of the strand. Therefore, the amount of powder consumed per unit of surface area(kg/m²) is most suitable for evaluating the lubrication capability of mold fluxes. 结晶器保护渣消耗量现已表示为不同的形式。如 kg/t 钢、 kg/m², kg/min。 然而，(保护渣)消耗量取决于连铸板坯尺寸并且与铸坯表面积成正比。因此，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。)
