硅铁合金是生产特殊钢材的重要原料,也是我国出口创汇的拳头产品。硅铁合金对其所含铬、钙的量有一定的要求,其含量的高低直接影响产品的质量,因此,快速简便地测定铬、钙的含量,是把握硅铁合金质量的关键。用原于吸收光谱法分别测定铬和钙,前人已做过一些工作,本文系在同一
Ferrosilicon alloy is an important raw material for the production of special steel, but also China’s leading foreign exchange earning products. Ferrosilicon alloy has certain requirements for the amount of chromium and calcium contained therein. The content of ferrosilicon directly affects the quality of the product. Therefore, the determination of chromium and calcium content quickly and easily is the key to grasping the quality of ferrosilicon alloy. With the original determination of chromium and calcium by absorption spectrometry, predecessors have done some work, this article in the same
