一、前言自从炉前分析室对磷的测定采用高速分析以来,对于碳素钢,一般合金钢,以及不含钨的高合金钢,均能准确及时地配合炉中冶炼生产,然而对于含钨钢中磷的分析,则始终未能满足生产要求,严重地影响分析质量,其主要原因是有关钨的沉淀问题未能适当地加以解决,针对这一问题,我们最近在不改变原高速分析方法的基础上,对含钨钢进行了一些试验,对原方法溶样部份稍加变动,采取了一些适当步骤,使该方法既不改 I. INTRODUCTION Since the analysis of phosphorus in the furnace front analysis room using high-speed analysis, for carbon steel, the general alloy steel, and high alloy steel without tungsten, can accurately and timely with the furnace smelting production, but for tungsten Analysis of steel phosphorus, it has failed to meet production requirements, seriously affecting the quality of the analysis, the main reason is that the problem of tungsten precipitation has not been properly addressed, in response to this problem, we recently did not change the original high-speed analytical methods Based on the tungsten-containing steel for a number of tests, the original method of the sample part of a slight change, take some appropriate steps to make the method neither change
