摘　　要：以烧结板状刚玉、锆莫来石、天然鳞片状石墨为主原料 ,酚醛树脂为结合剂 ,Al、Si、B4C、Mn粉为添加剂 ,经 1 4 50℃埋炭烧成后 ,制成铝炭和铝锆炭系列试样 ,并对各试样的抗渣侵蚀性能进行了对比研究。结果表明 :在铝锆炭材料中 ,当Mn与Al、Si复合加入且Mn与C的质量比为 1∶4时 ,试样的抗侵蚀性和渗透性均较好 ;在铝炭材料中 ,当Mn与Al、Si、B4C复合加入且Mn与C的质量比为 1∶4时 。Al 2 O 3 -C and Al 2 O 3 -ZrO 2 -C specimens were prepared using sintered tabular corundum,zirconia-mullite and natural flaky graphite as major materials,powders of Mn,Al,Si,B 4 C as additives and phenolic resin a s cement.The specimens were sintered at 1450 ℃.The slag resistances of the Al 2 O 3 -C and Al 2 O 3 -ZrO 2 -C materials were studied.Resear ch results show that slag resistance of Al 2 O 3 -ZrO 2 -C materials is good when Mn is added with Al,Si,and the mass ratio of manganese to carbon i s 1∶4.Penetration resistance of Al 2 O 3 -C is good when Mn is added with Al,Si,B 4 C,and the mass ratio of manganese to carbon is 1 ∶4.
