Abstract

PURPOSE:To mold additive for continuous casting which is obtained by mixing alkali silicate glass at the specific ratio in the powder of the amorphous basic fluorine-contained calcium silicate of less contents of oxides of Al and Fe as impurities and which is inexpensive and has higher cleaning capacity for slab surfaces. CONSTITUTION:The powder of the fluorine-contained calcium silicate shown by general formula yCaO.SiO2.xF and the powder of alkali silicate glass such as sodium silicate are mixed and the mixture is granulated by a water glass solution, whereby the mold additive for continuous casting is prepared. In this case, the values of x, y in the above formula are the values within the range where the A, B, C, D of the figure are encircled and the water granulated slag by-produced at the production of white phosphorus of 10% or less in contents of Al2O3, Fe2O3 as impurities is used. The compounding ratios are: The molar ratios of Na2O or K2O: CaO.SiO2: F of the alkali silicate glass are 0.1-0.3:0.8-1.5:0.3-0.8.
