Effect of Addition Amount of Mullite Sols on Property of Corundum Castable
摘 要
以共沉淀法制备的莫来石溶胶为结合剂,在不同温度(1 100,1 300,1 500 ℃)烧结制备了刚玉质浇注料,研究了莫来石溶胶添加量对刚玉质浇注料物相组成、烧结性能、常温耐压强度和微观结构的影响。结果表明:随莫来石溶胶添加量的增加,试样的体积密度先增后降,显气孔率先降后增;试样的物相均主要为刚玉相和莫来石相,随着烧结温度的升高和莫来石溶胶添加量的增加,莫来石相的含量增加,试样的常温耐压强度增大;当莫来石溶胶的质量分数为3%时,1 500 ℃烧结试样的常温耐压强度最大。
Abstract
With the mullite sols prepared by coprecipitation method as a binder, the corundum castable was sintered at different temperatures (1 100,1 300,1 500℃). The effects of addition amount of mullite sols on the phase composition, sintering performance, compressive strength at ambient temperature and microstructure of the corundum castables were studied. The results show that with the increase of mullite sols addition amount, the bulk density of the sample first increased and then decreased; the apparent porosity first decreased and then increased. The phase composition of the sample mainly consisted of corundum phase and mullite phase. With the increase of sintering temperature and addition amount of mullite sols, the content of mullite phase increased; the compressive strength at ambient temperature of the sample was improved. When the mass fraction of mullite sols was 3%, the compressive strength at ambient temperature of the sample sintered at 1 500℃ was the largest.
