Chromite Sand for Ladle Drainage Sand is originally from South Africa’s Chrome ore. Chromite sand AFS30-35 & AFS35-40 are the main raw material for producing chromium-based ladle filler sand. It has the characteristics of high sintering temperature and strong thermal conductivity. Chromite filler sand, as the drainage medium for the ladle, can quickly form a sintered layer, thereby improving the opening rate of pouring.
