QT500-14风电主轴的铸造工艺开发

Casting Process Research of QT500-14 Wind Turbine Spindle

高硅球墨铸铁QT500-14材料具有良好的力学性能,可应用于大功率风力发电机组的主轴,大幅度降低机组成本。通过严格控制材料QT500-14的化学成分、采用金属型铸造、通过MAGMA软件模拟主轴铸造工艺预测铸造缺陷,在主轴铸造过程中采取在预测缺陷位置处放置冷铁的控制措施,铸造出符合设计要求的风电主轴。

High silicon ductile iron QT500-14 material has good mechanical properties and can be applied to the casting of high-power wind turbine spindle to reduce the unit cost significantly.By strictly controlling the chemical composition of QT500-14,casting with metal mold,simulating the spindle casting process with MAGMA software,predicting the casting defects,and taking measures to place chill at the predicted defect position in the actual casting process,the wind turbine spindle meeting the design requirements has been cast.
