一概述随着钢铁工业的迅速发展,氧气顶吹转炉炼钢在世界各国得到广泛应用。氧气顶吹转炉炼钢的特点是,吹炼时间短,每炉只用15分钟左右,降碳速度快。为了控制终点碳,在炉前化验室进行化学分析,最快也得5-10分钟。直读光谱分析及X-萤光光谱分析虽能同时分析钢中多种元素,但由于仪器复杂,投资大,不能直接装在炉前,从取样到报出结果仍需4～5分钟。所以这些方法的分析速度远远不能满足炉定定碳的要求,影响了钢的产量和质量的提
An overview With the rapid development of the steel industry, oxygen top converter steelmaking in the world are widely used. Oxygen top converter steelmaking is characterized by a short blowing time, only about 15 minutes per furnace, carbon reduction speed. In order to control the end of carbon, chemical analysis in the furnace before the laboratory, the fastest 5-10 minutes. Direct reading spectroscopy and X-ray fluorescence analysis can analyze many elements in steel at the same time. However, due to the complicated equipment and large investment, it can not be installed directly in front of the furnace. It still takes 4 to 5 minutes from sampling to report the results. Therefore, the analysis speed of these methods can not meet the requirements of the furnace to determine the carbon, affecting the yield and quality of steel
