| 摘 要： | 利用化学分析、X射线衍射仪、电子探针以及热力学等方法对攀钢铁水罐用后高铝残砖进行了分析.结果表明:残砖几乎没有挂渣层.舍钒钛渣由于表面张力小,黏度低,在高铝砖中的渗透很深;渣中的V2O5、TiO2、MnO、FeO等与高铝砖中组分反应生成的固溶体和化合物(如尖晶石、刚玉、钙长石等)中均发现固溶有V2O5;变质层的形成导致了致密化热震剥落;而较高的气孔率也是高铝砖损毁严重的另一重要原因.

| Abstract: | Used bauxite based brick in torpedo ladle of Pangang Group Co.,Ltd.was analyzed by means of ICP-AES,XRD,EPMA,and thermodynamics.The results show that:(1)there is hardly any slag layer adhering on the used brick;(2)the vanadium and titanium containing slag penetrates into the bauxite based brick deeply because of low surface tension and viscosity;(3)V2O5 is found in the solid solution and compounds(such as spinel,corundum,and anorthite) formed by the reactions of V2O5,TiO2,MnO,and FeO in slag with the compon... |
