Abstract

Low carbon steel fluoride free continuous casting mold powders comprise NaO 5% 10% MgO 3% 10% MnO 3% 10% ?O 3% 10% ?lO = 6% LiO < 3% C 1% 3% the components being counted in weight percentage and the margin being CaO SiO and unavoidable impurities and CaO/SiO being 0.8% 1.3%. The melting point thereof is 950°C 1150°C and 1300°C and the viscosity is 0.1 Pa.s 0.3 Pa.s. After being melted at 1350°C 50g of mold powders are poured into a steel crucible for natural cooling the proportion of a section crystal is used for representing that the crystallization rate of the mold powders is in the range of 10% 50%. The boric fluoride free mold powders have a modest crystallization rate can effectively control the heat transfer of molten steel by a mold and are successfully applied in a low carbon steel slab caster so the metallurgical effect completely reaches the level of conventional fluorine containing powders.
