Study On Die Of Electrode Ingot Pouring Process Based On ProCAST

The characteristics of electroslag remelting is produced to obtain good qualitysteel ingot or casting under the refining. The ingot of electroslag remelting hasobvious advantages compared to traditional casting, because the heat transferdirection of electroslag remelting is much clearer. In addition to outside the ingotsurface has a layer of the chilling, in the ingot is given priority to with column strongcrystal structure, and due to the bottom and sides in the crystallizer forced watercooling effect, quicken the solidification rate of metal, at the same time of reducingsegregation, effectively control the crystallization direction, so the electroslag ingot isgiven priority to with tending to the crystallization of axial organization. Along withour country the growth of the national economy and social purchasing powercontinues to grow, the electrode ingot quality requirements also more and more high,and the pure traditional electrode ingot casting experience in order to meet the futuredevelopment, combined with the simulation of computer software will be the trend ofthe times.Metal mold casting process based on the mathematical physical model,numerical simulation according to the actual production conditions, set up the initialconditions and boundary conditions, using ProCAST software to phi450ingot castingfilling and solidification process of the internal process of temperature field, flowfield in visual observation. Control variable method, design of ingot and riser with acertain pouring time than the schemes for the multiple variable speed of pouring,compare the temperature field during the filling process, solidification time and thedistribution of top shrinkage degree after choose the optimal solution. On the analysisof the numerical simulation results: when the electrode time of the riser casting ingotingot casting body ratio of3:7, pouring temperature of1520℃, pouring the besteffect.
