| titleOfInvention | Lightweight periclase-magnesium-iron-aluminum composite spinel refractory material and preparation method thereof |
| abstract | The invention relates to a lightweight periclase-magnesium-iron-aluminum composite spinel refractory material and a preparation method thereof. The technical scheme is as follows: 10-22 wt%, 25-41 wt% and 15-31 wt% of porous periclase-magnesium-iron-aluminum composite spinel ceramic particles with the particle sizes of 3-5 mm, 1-2.8 mm and 0.1-0.8 mm in sequence are used as aggregates, 4-8 wt% of porous periclase-magnesium-iron-aluminum composite spinel ceramic fine powder with the particle size of less than 0.074mm and 15-27 wt% of magnesite fine powder are used as matrixes, and the sum of the aggregates and the matrixes is used as a raw material. Placing aggregate into a stirring pot, stirring, adding a sulfurous acid paper pulp solution with the weight percent of 3-8% of the raw material, stirring, adding a matrix, stirring, forming, drying, preserving heat at 1520-1620 ℃, and cooling to obtain the lightweight periclase-magnesium iron aluminum composite spinel refractory material. The product prepared by the invention has the characteristics of low heat conductivity coefficient, uniform distribution of microstructures, good kiln coating hanging performance and good erosion resistance, and can be applied to a second-generation novel cement rotary kiln. |
