As a MAGMASOFT® user, LIVAR was familiar with the possibilities of the core shooting simulation and turned to its contact in Slovenia, the company EXOTERM-IT. MAGMA C+M was implemented to investigate and solve the problem.
The first simulation was performed with standard data. However, in the critical area, the results still showed too high sand densities. Therefore, it was decided to first calibrate the sand properties and shooting parameters. For this purpose, a virtual design of experiments was defined in MAGMA C+M, and a total of 36 designs with different sand properties were tested. The results were compared in the critical zone with an evaluation area. Using the main effects diagram, which shows the influence of different sand and process conditions on the core density, optimized sand data for LIVAR could be determined.
