Casting Numerical Simulation Technology Application In Representative Steel Casting

With casting CAD/CAE practical technology application development and the corresponding commercialized software using wider and wider, the CAD/CAE technology using to product development and quality improving has great economic and academic significance.In this paper the casting CAE technology and its development has been analysed. The mathematics model making, the solution of equations and the factors of flow field, temperature field and stress field have been studied.The defect problems of some typical castings have been solved using casting CAD/CAE. Three-dimensional modeling of Front-end casting of mining machinery, casting of Vane hydraulic-turbine and Blade casting of hydraulic-turbine runner are built using CAD software IronCAD. The flow field of Front-end casting, temperature field of Vane casting and stress field of Blade casting are simulated using casting numerical simulation software MAGMAsoft.The following cast processes was simulated and optimized using CAD/CAE software:1. Front-end casting filling course has been simulated using numerical simulation technology. The comparative study of simulation of tradition gating system and improved gating system indicate that tradition gating system has turbulent form filling in molten steel, a large number of gas cavity made in surface and inside of casting. When using improved gating system, not only molten steel fills steady but also there is no gas cavity of casting surface and inside of product.2. Temperature field of solidify process of vane casting was simulated. The location of shrinkage cavity and shrinkage porosity was predicted. The temperature field solidified in proper order was set up. The appropriate foundry technique according to it used in vane casting production and there is not shrinkage cavity and shrinkage porosity.3. The stress field simulation during solidify process of hydraulic-turbine runner blade casting was made. The deformation of casting caused by stress field was predicted. Following the result the oppose deformation allowance in the production process of the blade casting was added. According to the result of simulation the blade casting was made, which deformation totally in the range of predict.Using CAD/CAE technology studied Front-end casting, Vane casting and Blade casting making process. The results direct production successful. With science exploration and application trying for CAD/CAE and technology, it goes on some beneficial technology to cast producing in the future.CAD/CAE technology application in cast industry studies the whole course of cast production speediness, nicety and low cost. This technology changes the experimental reliance of the casting technology scheme making. It assures casting quality, saves casting cost and raises casting productivity. It can also promote cast technological progress.
