Torpedo ladle lining smearing repair material, preparation method and use method
The invention discloses a torpedo ladle lining smearing repair material, a preparation method and a use method. The torpedo ladle lining smearing repair material comprises three Al2O3-containing usedrefractory reclaimed materials with different granularities and two brown fused alumina with different granularities, and the surfaces of the three Al2O3-containing used refractory reclaimed materialswith different granularities and the two brown fused alumina with different granularities are coated or partially coated with nano carbon films; wherein the thickness of the nano carbon film is 20-200 nanometers, and the fixed carbon content of the nano carbon film is more than or equal to 90%. The repair material has the characteristics of low raw material cost, wide renewable resource source, excellent thermal shock resistance, high interface bonding strength of a repairing layer, strong slag iron erosion resistance, simplicity and convenience in preparation and application and the like. Bymeans of the repair material, the service life of the torpedo ladle is prolonged, the consumption and maintenance cost of torpedo ladle refractory materials are reduced, the heat preservation and insulation performance of the torpedo ladle refractory material lining is improved, and the temperature drop of molten iron is reduced.
本发明公开了一种鱼雷罐内衬涂抹修补料、制备方法及使用方法，包括三种不同粒度的含Al2O3用后耐火再生料和两种不同粒度的棕刚玉，三种不同粒度的含Al2O3用后耐火再生料和两种不同粒度的棕刚玉表面包覆或部分包覆纳米碳膜，纳米碳膜的厚度为20～200纳米，纳米碳膜固定碳含量≥90％。具有原料成本低廉、再生资源来源广泛、热震稳定性优良、修补层界面结合强度大、抗渣铁侵蚀能力强、制备与应用简便等特点，达到延长鱼雷罐服役寿命、减少鱼雷罐耐火材料消耗与维护成本、提高鱼雷罐耐火材料衬保温隔热性能、降低铁水温降等综合使用目的。
