Improvement of Casting Process for Wind-Driven Generator Accelerator Planet Carrier
摘要
Abstract
Ductile iron planet carrier applied in wind-driven generator accelerator has thick wall of inner tooth and it takes a long time to finish eutectic solidification along with a high solidification expansion pressure, which causes the defects of shrinkage porosity. The test casting process is optimized, according to the simulation results of the filling and solidification and the actual casting process. The productive practice indicates that the defect of shrinkage porosity is solved and technological yield of casting increased by 15.13% with the optimized process.关键词
