Title:
REFINING METHOD OF MOLTEN LOW CARBON IRON
Document Type and Number:
Japanese Patent JPH11193411
Kind Code:
A
Abstract:

To efficiently and economically achieve the refining of the molten low-carbon iron such as the molten reducing iron including the desulfurization without causing any problems such as dropping of the temperature of the molten iron and adhesion to the base metal.

A method for refining the molten low-carbon iron containing ≤4 wt.% C after separating the slag and after separating iron from the slag, comprises a process 2 to achieve the desulfurization by adding and stirring the desulfurizing agent into the molten iron in an iron melting and refining vessel, a process 3 to heat and/or carburize the molten iron in the molten iron refining vessel or other molten iron refining vessel before or after the desulfurization, and a process 4 to decarburize the molten iron through these processes in a decarburizing furnace.
