摘要
介绍了钢渣铁精粉通过二次制样,使样品粒度均匀,满足化学分析要求,采用三氯化钛还原-重铬酸钾容量法测定全铁量。试验结果表明,本方法测试结果重复性良好,测定结果控制在国标误差范围内。
The,, sample of steel slag iron powder by twice preparations would have homogeneous grain size and meet the requirements of chemical analysis. And the total iron content was determined by the titanium trichloride reduction and potassium dichromate volumetric method. The test results showed that the determination results of this method have good repetitiveness and are controlled in the range of national standard allowable errors.
