METHOD OF PRODUCING MAGNESIA/CARBON BASED REFRACTORY
To further densify magnesia/carbon based refractory.SOLUTION: There is provided a method of producing magnesia/carbon based refractory, comprising a process of adding a phenolic resin to a refractory material mixture containing magnesia and carbon, and blending and molding the mixture to obtain an intermediate product 1. Thereafter, the intermediate product 1 is heat-treated at a temperature of higher than 100°C and 200°C or lower to obtain an intermediate product 2. Further, the intermediate product 2 is cooled to a temperature of 35°C or lower to obtain an intermediate product 3. Finally, the intermediate product 3 is heat-treated at a temperature of 200°C or higher and 300°C or lower. Thereby, the product can be densified to a greater extent relative to a conventional method and its structural degradation can be prevented.SELECTED DRAWING: None
【課題】マグネシア・カーボン質耐火物の緻密化をさらに進める。【解決手段】マネシア・カーボン質耐火物の製造方法であって、マグネシアとカーボンを含む耐火原料混合物にフェノール樹脂を添加して混練、成形し中間製品１を得る。次いで、前記中間製品１を１００℃超、２００℃以下で熱処理して中間製品２を得る。更に、前記中間製品２を３５℃以下まで冷却して中間製品３を得る。最後に、前記中間製品３を２００℃以上、３００℃以下で熱処理する。これによって、従来よりもさらに緻密化し、組織劣化を防止することができる。【選択図】なし
