Nano-sol combined siliceous refractory castable and preparation method thereof
The invention discloses a nano-sol combined siliceous refractory castable which replaces silica bricks and is used on thermal kilns such as a carbonization chamber, a combustion chamber and a partition wall of a coke oven, a glass tank furnace and a kiln crown, a tank wall, a high-temperature bearing part of a hot blast stove, a carbon roasting furnace and the like. Comprising more than or equal to 90% of waste silica brick SiO2, more than or equal to 98.5% of silica fine powder SiO2, more than or equal to 98.5% of metal silicon powder Si, more than or equal to 90% of silica micropowder SiO2, more than or equal to 75% of nano aluminum gel powder Al2O3, more than or equal to 4.5 m < 2 >/g of BET, 40-41% of stabilizer nano silica sol SiO2, less than or equal to 0.3% of Na2O, pH of 9.0-10.0, viscosity of less than or equal to 25.0 mPaS and average particle size of 10-12 nm. The castable can be used for local repair of coke ovens, carbon calcining furnaces and glass kilns, and can also be used for integral casting molding.
本发明公开了一种一种代替硅砖用于焦炉的炭化室、燃烧室和隔墙、玻璃池窑和窑顶、池墙、热风炉的高温承重部位、炭素焙烧炉等热工窑炉上的纳米溶胶结合硅质耐火浇注料；包括废硅砖SiO2≥90%，硅石细粉SiO2≥98.5%，金属硅粉Si≥98.5%，硅微粉SiO2≥90%，纳米铝凝胶粉Al2O3≥75%，BET≥4.5m2/g，稳定剂纳米硅溶胶SiO2：40%‑41%，Na2O≤0.3%，PH9.0‑10.0，粘度≤25.0mPa•S，平均粒径10‑12nm。该浇注料即可用于焦炉、炭素煅烧炉和玻璃窑局部修补，也可用于整体浇注成型。
