Silicon carbide olivine refractory castable for household garbage incinerator lining
The invention provides a silicon carbide olivine refractory castable for a lining of a household garbage incinerator. A component A comprises forsterite fine powder, sintered magnesia fine powder, silica powder, caustic-burned magnesia powder, quartz sand fine powder, ferro-silicon nitride, sodium citrate and phenolic resin; a component B comprises forsterite fine powder, sintered magnesia fine powder, silica powder, caustic-burned magnesia powder, quartz sand fine powder, ferro-silicon nitride, sodium citrate and phenolic resin; a component C comprises forsterite particles and sintered magnesia particles; a component D comprises silica powder, ferro-silicon nitride, citric acid, monatomic silicon powder, forsterite fine powder, dextrin and water; a component E comprises explosion-proof fibers and a water reducing agent; and the component A and the component B are subjected to heat treatment in a neutral protective atmosphere, and then are subjected to crushing, ball milling and screening. According to the invention, forsterite is used for replacing part of magnesia raw materials, and the obtained olivine castable effectively reduces environmental pollution and has the characteristics of high strength, good compactness, good slag corrosion resistance and good construction fluidity.
本发明提供一种用于生活垃圾焚烧炉内衬碳化硅橄榄石耐火浇注料，A组分包括镁橄榄石细粉、烧结镁砂细粉、硅微粉、轻烧镁粉、石英砂细粉、氮化硅铁、柠檬酸钠、酚醛树脂；B组分包括镁橄榄石细粉、烧结镁砂细粉、硅微粉、轻烧镁粉、石英砂细粉、氮化硅铁、柠檬酸钠、酚醛树脂；C组分包括镁橄榄石颗粒、烧结镁砂颗粒；D组分包括硅微粉、氮化硅铁、柠檬酸、单质硅粉、镁橄榄石细粉、糊精和水；E组分包括防爆纤维、减水剂；A组分、B组分中性保护气氛下热处理，再经破碎、球磨和筛分。本发明使用镁橄榄石替代部分镁砂原料，获得的橄榄石浇注料有效的降低了环境污染，并且具有高强度、致密性好、抗渣侵蚀性能好、施工流动性好的特点。
