Effects of li-based mold fluxes
WebMold fluxes play a crucial role during the continuous casting of steel:1)they prevent steel reoxidation and freezing of the steel surface, absorb non-metallic inclusions, control horizontal heat transfer and provide lubrication throughout the strand. WebDec 15, 2024 · When using conventional silicate-based mold flux for continuous casting to produce special steels, reactions occur between the molten mold slags and the molten steel; the metallurgical roles change, resulting in deterioration of the continuous casting conditions [ [5], [6], [7], [8] ].
