为了适应炼钢炉前的需要,我们对五元素快速分析摸索出一些经验。经多年实践证明,我们采用这些经验进行炉前分析,不仅快速、稳定、精确,而且易于掌握,节约瓷舟与药品。一、炉前磷的定标快速分析法 1、定标法根据炉前出钢样,磷必须小于0.030％的要求,我们采用磷含量为0.03％的标钢,在比色计上固定吸光度为0.30炉前样与其比较,报出合格与否的方法。单样分析时间为70秒。满足了炉前“快、准”的要求。
In order to meet the needs of the steelmaking furnace, we explored some of the rapid analysis of five elements of the experience. After years of proven, we use these experiences for pre-furnace analysis, not only fast, stable, accurate, but also easy to grasp, saving porcelain and medicine. First, the calibration of furnace phosphorus rapid analysis method 1, calibration method According to the sample from the furnace before, phosphorus must be less than 0.030% of the requirements, we use 0.03% phosphorus content of standard steel, the fixed absorbance of the colorimeter 0.30 before the stove compared with the way to declare the pass or not. Single analysis time is 70 seconds. Meet the stove before the “fast, accurate” requirements.
