| 摘 要： | 本文分别采用挂片失重法、线性极化法、极化曲线法研究了反应温度、物料配比、反应时间、萤石中所含杂质等因素对碳钢在萤石-硫酸体系中的腐蚀影响，结果表明：降低反应温度、控制杂质含量在一个较低水平都可以有效的降低碳钢的腐蚀速率；增加物料配比中硫酸的比例，会导致碳钢出现某种程度的钝化；碳钢在萤石-硫酸体系中的腐蚀存在着一个严重腐蚀阶段，在本文的实验条件下，该阶段为物料开始反应的前4分钟。

| Abstract: | The main factors influencing corrosion of carbon steel are studied by weight loss, linear polarization and polarization curves methods in this study. The results show that the corrosion rate of specimen decreased with reducing temperature and the impurity content. The carbon steel can passivate in some proportion between fluorite and sulfuric acid. The corrosion rate of carbon steel is more serious in the first 4 minutes of reaction. |

| Keywords: | Anhydrous Hydrogen Fluoride corrosion rate influencing factors impurity content temperature passivate |
