| 摘 要： | 在制砖基料中加入２０％铬渣，制成所要求几何形试块，按给定的烧成温度烧成试块，测量烧成块几何尺寸和烧成前后试块所含水溶样Ｃｒ（Ⅵ）值，将烧成试块置于不同条件的浸出液中进行长期浸取，根据Ｉａ的浸出数据，浸出率ＬＲ＝０．８×１０＾－７ｃｍ／ｄ，累积浸出分数ＬＦ＝１×１０＾－４ｃｍ，判断炻质砖试块中Ｃｒ（Ⅵ）的稳定程度，从而判定此处理铬渣方法的可行性。

| Abstract: | By adding 20% chromium-bearing slag into base materials of making brick, the brick sample was sintered in the required geometric shape under the given temperature. The size of sintered base sample was measured and the associated Cr water solubility test made before and after sintering. The sample was tested in leaching liquid under variable conditions. Based on the experiment results data,the leaching rate is 0.8×10-7 cm/d and the accumulative leaching faction is 1×10-4 cm/d, the stability of Cr in base sample was determined and therefore such method of treating chromium slag was considered feassible and practible. |
