废钢中有锌的存在会加大炼钢生产的困难,并会引起环境污染。本文介绍了一种采用空气和氯气的混合气体去除熔炼前废钢中锌杂质的分离方法。热动力学表明,锌氯化合物比锌氧化合物稳定,铁则相反。在实验中,温度为800℃时,空气和氯的混合气体(10:1)可以有效的去除钢中锌杂质。多种分析技术对反应产物特性的分析结果进一步证实了热动力学的结论。这是一种 The presence of zinc in scrap increases the difficulty of steelmaking and can cause environmental pollution. This paper presents a separation of zinc impurities from scrap steel before smelting using a mixture of air and chlorine. Thermodynamics shows that zinc and chlorine compounds are more stable than zinc and oxygen compounds and iron is the opposite. In the experiment, a mixed gas of air and chlorine (10: 1) can effectively remove zinc impurities in steel at a temperature of 800 ℃. The results of the analysis of the reaction product characteristics by various analytical techniques further confirm the conclusion of the thermodynamics. This is a kind
