Preparation method of long-service-life prefabricated part for solid hazardous waste incineration rotary kiln
The invention relates to a preparation method of a long-life prefabricated part for a solid hazardous waste incineration rotary kiln. The preparation method comprises the following steps: uniformly dry-mixing raw materials comprising, by mass, 40-70 parts of fused chrome corundum particles, 0-30 parts of corundum granules, 5-15 parts of spinel fine powder, 3-10 parts of chromium oxide fine powder, 4-10 parts of activated aluminum oxide micro powder, 2-6 parts of pure calcium aluminate cement and 0.2-0.4 parts of a high-efficiency water reducing agent, then adding 4.2-5 parts by mass of water,and uniformly stirring all the components; and carrying out vibration casting molding to obtain an anti-erosion castable working layer A. According to the invention, the prefabricated part is energy-saving, convenient to construct, excellent in thermal spalling resistance and long in service life, and the kiln coating temperature of the rotary kiln is obviously reduced compared with that of a traditional refractory material.
本发明涉及一种固体危废焚烧回转窑用长寿命预制件的制备方法，将质量份数为40‑70的电熔铬刚玉颗粒、质量份数为0‑30的刚玉颗粒、质量份数为5‑15的尖晶石细粉、质量份数为3‑10的氧化铬细粉、质量份数为4‑10的活性氧化铝微粉、质量份数为2‑6的纯铝酸钙水泥以及质量份数为0.2‑0.4的高效减水剂干混均匀后再加入质量份数为4.2‑5的水搅拌均匀，经振动浇注成型得到耐抗侵蚀浇注料工作层A；具有节能，施工方便，抗热剥落性能优良，使用寿命高，且回转窑窑皮温度较传统耐火材料有明显降低。
