摘　　要：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.A new concept named 'non-carbon metallurgy by solar energy photovoltaic technology' was put forward through the analysis of the iron source usage and the carbon metallurgy process. The main study included smelting at high temperature,no-carbon reduction,and melting-reduction. The experimental system with 1-kg capacity was designed and manufactured. Three kinds of experiments were carried out. It shows that the concept of 'non-carbon metallurgy by solar energy photovoltaic technology' is feasible and the system can meet the needs of smelting. The conversion rate of the photovoltaic cell is 9.8% and the steel enthalpy accounts for 5% of the total energy consumption in the high temperature smelting experiment. The current efficiency is 85.1% with the highest being 97.6% during the electrolysis process. The decrease order of influence on the reduction degree of Fe2O3 is atmosphere temperature,time,and particle size in the hydrogen reduction process. According to the results,further study is needed to get better economy,stability,and operability of this system.
