PREPARATION METHOD OF DOLOMITE REFRACTORY WITH GOOD HYDRATION RESISTANCE

摘要

PURPOSE: A method for preparing a dolomite refractory is provided, to obtain a dolomite refractory with the improved the hydration resistance by recycling the slurry generated in the perite manufacturing process. CONSTITUTION: The method comprises the steps of adding the perite slurry comprising 65 wt% or more of Fe2O3 and 40 wt% or less of the Mn-Zn-Ni component to a dolomite clinker in the content of 5-15 wt% based on the content of CaO contained in the dolomite clinker and mixing them; molding the mixture; and calcining the molded one.
