精密铸造不锈钢弯管支架的工艺优化
Process Optimization of Precision Casting Stainless Steel Bending Bracket
摘要
Abstract
Through UG modeling and AnyCasting software,the precision casting numerical simulation of 304 stainless steel bending bracket was carried out,the distributions of shrinkage cavity defects of the casting were predicted,and the gating system was improved.By analyzing the structure of castings,the process parameters such as roasting temperature and pouring temperature were changed,and the actual production was carried out.Metallographic microscopy(OM)and scanning electron microscopy(SEM)were used to detect and analyze the samples before and after process optimization.The results show that the macroscopic and microscopic shrinkage cavity and porosity defects of castings were significantly reduced,the mechanical properties were improved,the number of inclusions was reduced,and the microstructure and hardness are more uniform.These provided references for the production of stainles steel thin-wall bending bracket castings.关键词
