摘　　要：通过对回收中间包涂料颗粒代替烧结镁砂颗粒的研究,以期达到降本增效、环保的目的。结果表明:随着代替量的增多,试样的体积密度与气孔率虽然没有明显的差异,但是经中、高温处理后,试样的抗折强度逐渐提高。当代替量超过20%时,抗渣性能有所降低,极大的降低了试样的高温抗折强度。The purpose of reducing cost and environmental protection is expected to be achieved through study on recycling coating material particles replace of magnesia sand particles. The result shows： no big differences in the bulk density and porosity of the sample is found as increasing substitution rate, in the mean time, the rupture strength of the sample is gradually in- creased after medium and high temperature treatment. When the substitution rate is more than 20%, the slag resistance is decreased, which greatly reduces the high temperature rupture strength.
