Aluminum-magnesium anhydrous stemming
The invention discloses aluminum-magnesium anhydrous stemming. The aluminum-magnesium anhydrous stemming is prepared from recycled molten trough castable, a recycled sliding plate, recycled alundum powder, recycled magnesia and finished product raw materials including coke particles, pyrophyllite, silicon iron nitride, high-temperature asphalt powder, magnesium clay powder and a mixed oil bindingagent according to a certain weight ratio. According to the invention, on the basis of the material and the characteristics of the aluminum-magnesium anhydrous stemming, a large proportion of recycledand regenerated refractory materials made of the similar material are adopted to replace original refractory materials, so the recycled and regenerated refractory raw materials are fully utilized, precious resources are saved, the raw material cost of the anhydrous stemming is reduced, selling price is reduced to 3500 yuan/ton, the damage of industrial solid waste emission to the ecological environment is reduced, and the national resource recycling policy is accorded with. The aluminum-magnesium anhydrous stemming prepared by the invention is actually used in front of a furnace, and the actual application effect reaches and exceeds the application effect of an anhydrous stemming product prepared from a primary refractory raw material.
本发明公开了一种铝镁质无水炮泥，是由回收铁水沟浇注料、回收滑板、再生刚玉粉、再生镁砂以及成品原料焦炭粒、叶蜡石、氮化硅铁、高温沥青粉、镁质粘土粉和混合油结合剂按一定重量份配比配制而成。本发明根据铝镁质无水炮泥的材质和特性，较大比例采用相近材质的回收及再生耐火材料取代了原生耐火材料，充分利用了用后回收及再生耐火原料，不但节约了宝贵资源，降低了无水炮泥原材料成本，销售价格降为3500元/吨，同时也减少了工业固废排放对于生态环境的破坏，符合国家资源循环利用政策。本发明配制的铝镁质无水炮泥经过炉前实际使用，实际应用的效果达到并超过了原生耐火原料制作的无水炮泥产品。
