一种焦炉加煤口整体座砖用浇注料及其制备和使用方法
摘要：
本发明公开了一种用于焦炉加煤口整体座砖用浇注料及其制备和使用方法，其含有粒度为5～8mm的莫来石15～35％，粒度为3～5mm的堇青石15～30％，粒度为0～3mm的氧化铀5～20％，粒度为0～1mm的氮化硼10～15％，粒度为180目的碳化硅4～10％，粒度＜0.088mm的二硅化钼5～10％，粒度为180目的磷酸盐5～10％，粒度为200目的硅微粉2～5％。该浇注料可满足焦炉加煤口整体座砖使用条件，内部应力小，热震稳定性好，对碳的润湿性低，不结石墨、不粘焦油。同时，该浇注料抗颗粒碳侵蚀和煤粉摩擦能力更强，使用寿命更长。
摘要（英）：

The invention discloses a castable for an integral seat brick of a coal charging port of a coke oven and a preparation method and application method thereof. The castable comprises 15-35% of mullite with the particle size of 5-8 mm, 15-30% of cordierite with the particle size of 3-5 mm, 5-20% of uranium oxide with the particle size of 0-3 mm, 10-15% of boron nitride with the particle size of 0-1 mm, 4-10% of silicon carbide with the particle size of 180 meshes, 5-10% of molybdenum disilicide with the particle size less than 0.088 mm, 5-10% of phosphate with the particle size of 180 meshes and2-5% of silicon micropowder with the particle size of 200 meshes. The castable can meet the use condition of the integral seat brick of the coal charging port of the coke oven, and has the advantagesof small internal stress, good thermal shock stability, low wettability to carbon, no graphite formation and no tar adhesion; and meanwhile, the castable is high in granular carbon erosion resistanceand pulverized coal friction resistance and longer in service life.
