摘　　要：用FeSiMg6RE2低镁球化剂分别对不同球化处理温度的铸铁进行了盖包法球化处理试验。通过对不同球化处理温度下铁液中镁吸收率、石墨大小和球化率、球铁力学性能的比较,分析了球化处理温度对球铁组织和性能的影响。The tundish-cover spheroidization treatment for cast iron was performed with FeSiMg6RE2 low Mg nodularizer at different temperatures. By comparing of Mg absorptivities in melted iron, the graphite sizes and spheroidization rate, and the mechanical properties of ductile iron at different temperatures, the effects of the spheroidizing temperatures on the microstructure and property of ductile iron were analyzed.
