Abstract
PURPOSE: To improve the desiliconization reaction efficiency of molten iron by specifying the ratios of CaO and Fe2O3 and yet limiting grain size range.
CONSTITUTION: The desiliconizing agent which is composed of CaO 20W30wt% and Fe2O3 55W80% and in which particles of grain sizes 100W300 mesh are contained more than 80% is prepared. The Fe2O3 in the components reacts with the Si in molten iron like the undermentioned reaction formula and the Fe component is recovered into the molten iron. 2/3Fe2O3+Si=SiO2+4/3Fe To use this produce, an injection method using inert gas such as N2 gas as carrier gas is most effective.
