| 摘 要： | 以矾土为主要原料,加入硅线石粉、SiO2微粉、活性A l2O3微粉、水泥等制备矾土基浇注料,研究了硅线石加入量(质量分数分别为0、4%、8%和12%)对浇注料常温性能和抗渣侵蚀性能的影响。结果表明:随着硅线石加入量的增加,浇注料的常温强度和体积密度下降,显气孔率增大;在浇注料中加入硅线石有助于提高试样的抗渣侵蚀性能,但加入质量分数大于8%时,试样抗渣侵蚀性能下降,渣渗透深度和侵蚀深度增加;硅线石加入质量分数为4%~8%时,浇注料的综合性能较好。

| Abstract: | Bauxite based castables was prepared using bauxite as main starting material,and adding sillimanite powder,SiO2 micropowder,active Al2O3 micropowder,and cement.The influences of sillimanite additions(mass percent:0,4%,8%,and 12%)on cold properties and slag resistance of bauxite based castables were investigated.The result shows that:(1)the cold strength and bulk density of castables decrease while the apparent porosity increases with the increase of the sillimanite addition;(2)the sillimanite improves the s... |
