分析铁合金中含碳量,常采用纯铁或低碳钢(含碳量已知)作为辅助助熔剂(以下称引燃试样),以气体容量法测定含碳量。如何扣除辅助助熔剂的含碳量是在实际工作中一个不容忽略的问题。现将我们所使用的扣除公式介绍如下,以供参考。
Analysis of carbon content in ferroalloy, often using pure iron or low carbon steel (carbon content is known) as an auxiliary flux (hereinafter referred to as ignition sample), gas volumetric method for the determination of carbon content. How to deduct the carbon content of auxiliary flux is a problem that can not be neglected in practical work. Now we use the deduction formula described below, for reference.
