摘　　要：通过大型风电球墨铸铁轮毂的研制,针对生产中出现的问题,摸索出大断面球墨铸铁轮毂生产工艺及质量控制措施。采用该工艺,通过严格选择原辅材料和严格控制铁液的化学成分,恰当的球化和孕育处理以及添加适量的微量合金元素,生产出各项性能指标合格的风电轮毂。结果表明,该生产工艺可行,技术措施得当。两年内共生产4种类型的风电轮毂400件,合格率达到96%以上。In view of the problem in producing heavy nodular iron hub of wind turbine generator, the processing technique and quality control measures were studied. The results show that qualified heavy wind turbine generator hub can be obtained by strict selection of raw and auxiliary materials, chemical composition control of molten iron, suitable nodulizing and inoculation treatment, trace element addition. 400 pieces of 4 types of wind power hub in all were produced in two years and the qualified ratio reached 96%.
