Embodiment Construction
[0020] A method of doping water-quenched slag to produce aerated blocks for high-temperature furnaces, the method comprising the following steps:
[0021] 1), after mixing furnace ash and phosphogypsum for crushing, take 12-20 parts of furnace ash and 1-3 parts of phosphogypsum in parts by mass;
[0022] 2) Before fine grinding, take 60-70 parts of phosphate slag and 1-2.5 parts of aluminum powder, and mix the crushed furnace ash, phosphogypsum, phosphate slag and aluminum powder evenly before fine grinding , the crushed furnace ash, phosphogypsum, phosphate slag and aluminum powder are evenly mixed and finely ground to a particle size of less than 21mm;
[0023] 3), breaking the water-quenched slag, and taking 15-25 parts by mass of the water-quenched slag;
[0024] 4) Put the crushed water-quenched slag and the finely ground dry material into the mixing equipment, add water to fully stir, and add 2-5 parts of foam stabilizer solution with a concentration of 8-10% and add P...
