Optimization of Investment Casting Process for Wheel Castings of Mining Flatbed Trucks
摘要
Abstract
The structure of mining flatbed wheel castings is complex,and defects such as shrinkage and shrinkage holes often occur in the process of investment casting.The pouring process of the casting was analyzed by numerical simulation software,and the results showed that there were many shrinkage holes at the bottom of the wheel rim,which seriously affected the quality of the casting.In order to reduce the porosity of the casting,the process scheme was improved,and the three process parameters of pouring temperature,pouring speed and shell preheating temperature were optimized.The influence of each process parameter on the porosity is mutual,and the optimal process combination is obtained through orthogonal tests.The optimized process parameters improve the process quality and production efficiency of wheel castings.关键词
