<P>PROBLEM TO BE SOLVED: To provide a method for melting solid-iron source in a molten iron carrier by which even in the case of beforehand laying dephosphorized bare metal and/or desulfurized bare metal recovered at the slag-off time after dephosphorization and/or desulfurization of the molten iron, there is no possibility of phreatic explosion. <P>SOLUTION: A technique with which the solid iron source is beforehand laid into the molten iron carrying vessel, the molten iron from a blast furnace is received and this solid iron source is melted by using the sensible heat and stirring force, is improved. In this method, as the solid-iron source, the dephosphorized bare metal and/or the desulfurized bare metal which are agglomerated and solidified at the size of 200-1,500mm and recovered in the high temperature state of 100-600°C are used in the slag generated with the dephosphorization and/or the desulfurization of the molten during leaving the slag in the yard. In this time, it is preferable to beforehand lay the dephosphorized bare metal and/or the desulfurized bare metal into the molten iron carrier by using a heat-resistant hydraulic-type heavy machine. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
