土法冶炼生铁,含硫量较高,硫是有害元素,直接影响着钢铁的质量的好坏。现在各地正采取措施向高硫开展斗争,必须把钢铁的含流量降低到最低限度。因此,化验工作担负着重大责任,必须把钢铁和矿石的含硫量及时地化验出来,解决冶炼钢铁的迫切需要。硫酸钡重量法定硫,要两三天的时间才能得出化验结果。操作比较复杂,需有仪器设备,对一般化验室相当困难。发生硫化氢的方法定硫比硫酸钡重量法要简便得多。但作为一个快速分析方法的要求,还存在一些问题。对于用酸不能全部分解的矿样,测定含硫量
Induction smelting pig iron, high sulfur content, sulfur is a harmful element, a direct impact on the quality of steel is good or bad. Now that everybody is taking measures to fight high sulfur, it is necessary to reduce the flow of steel to a minimum. Therefore, the laboratory work has a major responsibility, we must promptly test the sulfur content of the steel and ore to solve the urgent need of smelting steel. Barium sulfate weight statutory sulfur, two or three days time to come to test results. The operation is more complex, requiring equipment, the general laboratory is quite difficult. The method of occurrence of hydrogen sulfide fixed sulfur than barium sulfate gravimetric method is much more convenient. However, there are still some problems as a requirement for rapid analysis. For acid can not be fully decomposed ore samples, determination of sulfur content
