通过现有铁源利用及碳冶金流程分析,提出了太阳能光伏非碳冶金概念.太阳能光伏非碳冶金研究包括高温冶炼、非碳还原介质的选择及还原-熔融三个方面.自主设计制造了1kg容量的太阳能非碳冶金系统,进行了三类非碳冶金实验.实验结果表明太阳能光伏非碳冶金在技术上可行,自主设计制造的太阳能光伏非碳冶金系统均能满足冶炼要求.高温冶炼实验光伏电池转换率9.8%,钢水热焓占总能量消耗5%;非碳还原制铁实验电解法电流效率平均为85.1%,最高可达97.6%;氢还原Fe2O3还原度影响因素由强到弱依次为:气氛、温度、时间、粒度.根据实验结果,研究还需深化,以寻求太阳能光伏非碳冶金系统更好的经济性、稳定性及可操作性.
Based on the existing iron source utilization and carbon metallurgy process analysis, the concept of solar photovoltaic non-carbon metallurgy was put forward.The solar photovoltaic non-carbon metallurgy research includes three aspects: high temperature smelting, non-carbon reduction media selection and reduction-melting.It independently designs and manufactures 1kg Capacity non-carbon metallurgical system of solar energy, three types of non-carbon metallurgical experiments were conducted.The experimental results show that solar photovoltaic non-carbon metallurgy is technically feasible, independently designed and manufactured solar photovoltaic non-carbon metallurgical systems can meet the smelting requirements.High temperature smelting experimental photovoltaic Battery conversion rate of 9.8%, the enthalpy of molten steel accounted for 5% of the total energy consumption; non-carbon reduction of iron in the experimental electrolysis current average efficiency of 85.1%, up to 97.6%; hydrogen reduction Fe2O3 reduction factors from strong to weak As: atmosphere, temperature, time, particle size.According to the experimental results, the research needs to be further deepened to seek better economy, stability and operability of solar photovoltaic non-carbon metallurgy system.
