Abstract

PURPOSE:To desulfurize iron or steel without causing the nozzle clogging, by mixing the cooling agent consisting of more than one kind out of MgO, CaO, etc. to the Mg desulfurizing agent containing Mg more than specified quantity and having the particle size below a specified value and by blowing the mixture into the molten pig iron, etc. together with the carrier gas.
