Environment-friendly anhydrous stemming for multi-taphole blast furnace, and preparation method thereof
The invention belongs to the technical field of refractory materials for blast furnaces, and discloses environment-friendly anhydrous stemming for a multi-taphole blast furnace, and a preparation method thereof. The stemming consists of, by mass, 38-45% of aggregate, 40-47% of powder and 10-16% of a composite binding agent, wherein the composite binding agent is formed by mixing Carbores T60, Carbores T10, environment-friendly anthracene oil, Carbores P and a wetting agent, the benzo a pyrene content of the composite binding agent is smaller than 150 mg/kg, and the moisture content of the composite binding agent is smaller than or equal to 1.0%. The raw materials comprise a plurality of regenerated refractory materials and carbon-containing raw materials, so the production cost can be reduced, meanwhile, the prepared stemming product is convenient to operate during use, moderate in drying speed, good in peristalsis and filling performance, easy to pug, easy to open, stable in taphole depth, resistant to scouring and stable in slag resistance, the consumption of per ton of iron stemming is smaller than 0.5 kg in practical application, the benzopyrene content is smaller than 25 mg/kg, the environment of a blast furnace production area can be better improved, and the body health of operators is guaranteed.
本发明属于高炉用耐火材料技术领域，公开了一种多铁口高炉用环保无水炮泥及其制备方法。所述炮泥由骨料、粉料和复合结合剂组成，按质量百分含量计，骨料为38％～45％；粉料为40％～47％；复合结合剂为10％～16％；所述复合结合剂由Carbores T60、Carbores T10、环保蒽油、Carbores P和润湿剂混合而成，所述复合结合剂的苯并a芘含量小于150mg/kg，水分含量≤1.0％。本发明原料中包含多种再生耐火材料和含碳原料，不仅有利于降低生产成本，同时制得的炮泥产品使用时操作方便，干燥速度适中、蠕动性和填充性好，好打泥，易开口，铁口深度稳定，抗冲刷、抗渣性能稳定，而其实际应用时的吨铁炮泥消耗量小于0.5kg，苯并芘含量小于25mg/kg，更有利于改善高炉生产区域环境，保证作业人员身体健康。
