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 barium titanate waste with low cost. CONSTITUTION: The method comprises the steps of adding the barium titanate waste to a dolomite clinker in the content of 1-10 wt% based on the amount of the dolomite clinker and mixing them; molding the mixture; and calcining the molded one. The barium titanate waste has a particle size of 1 mm or less, and its barium titanate content is 90% or more.
