Many foundry enterprises also use casting simulation analysis software to improve the process. Xiazezi and others from China shipbuilding industry group carried out three-dimensional simulation by using Huazhu CAE to verify the feasibility and reliability of steel casting process. Through production practice and process analysis of several methods (CAE simulation analysis, riser feeding efficiency analysis, thermal nodal circle method analysis and modulus method analysis), Mou Xiangshan and others of Shandong East Asia Machinery Co., Ltd. confirmed that setting the riser at the position deviating from the thermal nodal can avoid the formation of new contact thermal nodal, reduce the shrinkage defect of castings and reduce the volume of riser, Improve the yield. Wang Jinyong and others from Xinxing Casting Pipe Co., Ltd. applied viewcast software to design the casting process and applied it to actual production. Finally, the internal structure of steel castings is dense and meets the technical requirements.
The h-dimensional simulation is carried out by using the integrated system of Huazhu CAE casting process analysis software. The system can analyze and optimize the casting process of steel castings. It is a software developed by Huazhong University of science and technology and continuously improved and improved in production practice. At present, in China’s foundry industry, Huazhu CAE integrated system is one of the most famous process analysis systems. At present, more than 100 industrial and mining enterprises and scientific research institutes in China use the system. Huazhu CAE system can complete the solidification, flow analysis, flow and heat transfer calculation and analysis of steel castings with various alloy materials and casting methods. Through application practice, this system can be used to predict the tendency of shrinkage cavity and porosity defects of steel castings, so as to optimize the casting process, improve the yield and shorten the trial production cycle.
