摘要: 采用稀土氧化物固态渣饼作为脱硫剂和球化剂,在吹氩条件下对高硫(S=0.100%)铁水进行球化处理生产球墨铸铁。在1380,1410和1450℃下均获得成功。在1450℃下处理45min左右其成功率为90%。获得球铁的碳当量为4.7%左右,RE含量为0.020—0.081%。对脱硫反应和稀土氧化物的还原反应进行了热力学分析,结果表明在本实验条件下上述反应在热力学上是可行的。实验事实和热力学计算均表明,固态渣饼在球化处理中可重复使用。
Abstract:A new spheroidization process was developed for production of nodular cast iron from high-sulphur (0.1%S) molten iron. The solid slag cake of rare-earth oxide was used as desulphurizer and spheroidizer under the Ar-blowing operation. The results achieved after the experiments under 1380, 1410 or 1450℃. Treatment at 1450℃ for about 45 min attended 90% of success. The carbon equivalent and the content of rare-earth for nodular cast iron produced are about 4.7% and 0.020—0.081% respectively. Thermodynamic analysis on the desulphurization and the reduction of rare-earth oxides has proved available for the experimental conditions. And it was indicated by both thermodynamic calculation and experimental practice that the solid slag cake may be used repeatedly.
