Method of surface treatment of sinter ore for improvement of RDI

摘要

PURPOSE: A method for water treating agglomerate is provided, for increasing the low temperature reduction differentiation strength of agglomerate in a furnace. CONSTITUTION: The method comprises the steps of controlling the acidity of aqueous solution to be above 7 and the concentration of Ca2+ to be above 4.4 ppm to prepare an aqueous solution; dipping agglomerate into the aqueous solution; drying the agglomerate; and charging the dried agglomerate into a furnace.
