碳化硅澆注料 NRT-ALPUMP-608SCX

碳化硅澆注料ALPUMP 408SCX

碳化硅澆注料:氧化鋁一碳化硅澆注料

氧化鋁一碳化硅澆注料是指 Al2O3為主要成分,SiC為次要成分的耐火澆注料。

中文名 氧化鋁一碳化硅澆注料 外文名 alumina-silicon carbide castable 

 Al2O3、SiC 

 燒結或電爐剛玉、黑色碳化硅 

 燒結或電熔剛玉粉、碳化硅粉 結合劑 純鋁酸鈣水泥

簡介:氧化鋁一碳化硅澆注料是用燒結或電爐剛玉、黑色碳化硅作為骨料,用燒結或電熔剛玉粉、碳化硅粉作為基質,結合劑用純鋁酸鈣水泥、或結合粘土加促凝劑、或硅溶膠加凝膠劑、或酸式磷酸鋁加促凝劑、或酚醛樹脂加交聯劑。

應用:

氧化鋁一碳化硅澆注料通常用作金屬熔液或熔渣的流槽和容器的內襯,如化鐵爐鐵水流槽、鐵水罐內襯、出鋼槽等,也可用作高溫耐磨襯里,如高溫旋風分離器內襯。

衍生發展:

在氧化鋁一碳化硅澆注料中還可加入碳素材料或氮化硅材料及少量的防氧化劑,如金屬硅粉和鋁粉等,配制成氧化鋁一碳化硅(氮化硅)一碳素澆注料,具有較好的耐熱震性、耐侵蝕性和耐沖刷性,可用作大、中型高爐出鐵溝內襯。其主溝鐵線以下和支鐵溝用澆注料化學成分為Al2O370~80%,SiC10~20%;主溝渣線以上和渣溝用澆注料化學成分為AI2O350~60%,SiC20~30%。
