新日本制铁公司开发出在炼钢过程中在线测定铁水中铬、锰等金属含量的系统。该系统除了设置在大分制铁所外，还决定在八幡等其它钢铁厂采用。迄今为止，分析金属成分都是从铁水中取样的，现在确立的连续分析转炉内金属元素燃烧时光谱的方法，能使钢的质量进一步提高。该测定系 Nippon Steel Corporation has developed a system for the on-line determination of metals such as chromium and manganese in hot metal during steelmaking. In addition to the system set up in Oita Iron and Steel, also decided to use Yawata other steel mills. So far, the analysis of metal components are all taken from the hot metal. The continuous analysis of the spectra of the metal elements in the converter at the present time, as established, can further improve the quality of the steel. This measurement system
