METHOD FOR PRODUCING RECYCLED REFRACTORY RAW MATERIAL
To provide a method for producing a recycled refractory raw material capable of sufficiently reducing the carbon content of the recycled refractory raw material.SOLUTION: The inventive method for producing a recycled refractory raw material includes: a granulation step in which carbon-containing refractory bricks are granulated to obtain granulated bricks; and a heat treatment step in which the granulated bricks are heated in the presence of an oxidizing gas to obtain a recycled refractory raw material, wherein the heating temperature in the heat treatment step is 1200°C or higher and the carbon content of the recycled refractory raw material is 1 mass% or less.SELECTED DRAWING: None
【課題】再生耐火原料の炭素含有量を十分に低減できる再生耐火原料の製造方法を提供する。【解決手段】炭素含有耐火れんがを細粒化して細粒化れんがを得る細粒化工程と、前記細粒化れんがを酸化性気体の存在下において加熱して、再生耐火原料を得る熱処理工程と、を含み、前記熱処理工程における加熱温度は、１２００℃以上であり、前記再生耐火原料の炭素含有量は１質量％以下である。【選択図】なし
