Castable for hazardous waste disposal industry
The invention provides a castable for hazardous waste disposal industry. The castable comprises, by mass, 50-70% of corundum and 10-30% of an anti-erosion agent; the anti-erosion agent is composed ofsilicon carbide, boron nitride and spherical asphalt; the mass ratio of the silicon carbide to the boron nitride is (3-5): 1; and the mass of the spherical asphalt accounts for 3-10% of the total massof the silicon carbide and the boron nitride. The castable for the hazardous waste disposal industry has good erosion resistance, abrasion resistance, acid and alkali corrosion resistance and the like; when being applied to a rotary kiln for hazardous waste disposal, the castable can greatly relieve erosion and abrasion of hazardous waste to a lining, prolongs the service life of the lining, reduces the overhaul frequency of the rotary kiln, and guarantees long-period stable operation of the rotary kiln, thereby improving the efficiency of the hazardous waste disposal.
本发明提供一种危废处置行业用浇注料，所述浇注料按质量百分比计，包括50～70％的刚玉和10～30％的抗侵蚀剂，所述抗侵蚀剂由碳化硅、氮化硼和球状沥青组成；其中，所述碳化硅与所述氮化硼的质量比为(3～5):1，所述球状沥青的质量占所述碳化硅与所述氮化硼总质量的3～10％。本发明提供的危废处置行业用浇注料具有良好的抗侵蚀性、耐磨性以及耐酸碱腐蚀性等，应用于危废处置的回转窑上，可大大缓解危废对内衬的侵蚀和磨损，延长内衬的使用寿命，减少回转窑的检修次数，保证回转窑的长周期稳定运行，从而提高危废处置的效率。
