铸铁中硅、锰、磷、铜四元素的分析,以往我们一直采用沪东造船厂编写的《金属的化学分析》一书中所介绍的分析方法。但随着我院附属工厂生产的发展,此方法在速度上已不能满足要求,为了提高铸铁中四元素的分析速度,我们对分析方法作了较大的改进,重新拟定了四元素的分析流程。经过几年的实践,证明此分析方法简便、快速,结果稳定、可靠,仪器设备简单,不需要三元素比色计,只要二个2型比色计就可同时测出硅、锰、磷三元素的
Analysis of four elements of silicon, manganese, phosphorus and copper in cast iron In the past, we have always adopted the analysis method described in the book Chemical Analysis of Metals written by Hudong Shipyard. However, with the development of subsidiary factory production in our hospital, this method can not meet the requirements in terms of speed. In order to improve the analysis speed of the four elements in cast iron, we made great improvements to the analytical methods and re-formulated the four-element analysis process . After several years of practice, this analysis method proved to be simple, fast, stable and reliable, the equipment is simple, does not require a three-element colorimeter, as long as two 2-colorimeter can simultaneously detect silicon, manganese, phosphorus three Element
