b'Engineer Innovation | Heavy EquipmentThe total time for the melt, starting fromcalculations. Calculation results of the the activation of the furnace to thesteps are transferred, as input to the next actual metal casting, has to be dividedstep of the workflow and to a common into time steps.workflow output.Each time step consists of independentThe first step is the time between the electromagnetic block made of astart of the heating process and the Simcenter MAGNET mode. Theactual melting of the top surface of the post-processing of all simulation dataload. It differs from other time steps will be done in Mathcad. The input in thebecause it requires a separate solid load Simcenter MAGNET model comes fromcalculation method. The rest is calculated the output of the previous step. Theby dividing the remaining time by the Simcenter MAGNET models makenumber of time steps without the first. electromagnetic calculations andTaking in to consideration the shape of transfer the results to MCD program. Thethe cold crucible segments, requires full MCD program uses the results for3D simulations of the electromagnetic thermal, hydrostatic and electrodynamicfields in Simcenter MAGNET. An example of cold crucible meshing is shown in Section Figure 5.Gap 1SectionGap 1 The results of Simcenter MAGNET 1 simulation after each step are transferred 2 1 to Mathcad postprocessing blocks. The blocks are responsible for providing the 1 1 2 following operations:2Calculation of temperature and energy 1 1 1 as in solid so in molten parts of load;Plane XZDetermination of load meniscus 1 shape; and 2Meniscus EM stabilization. 1 1 The results of each time step are integral parameters and shape of the molten load. The results are transferred to the a) b) next time step input.Figure 5:Cold crucible meshing. a) section surfaces b) plane XZ cross section.1- section mesh layers (3x0.3mm), 2-gaps mesh layers (4x0.1 mm)Figure 6 is the result of thermal analysis, 2000 1601800 140 2Temperature, C Distance from load bottom, mm1600 1 120 314001200 10021000 80 1800 60600 340400200 200 0 4 8 12 16 20 2428 32 36 4044 48 5256 60 64 68 72 7680 84 88 92 96 0 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1Time, Sec Relative distance from load axisFigure 6: Determination of initial molten load front at one of time step Figure 7: A profile of partially molten load after 80 sec (step2).1-surface T at 50mm from load bottom, 2-axis T at 98 mm from load1-load solid part, 2-molten load after iteration, 3-molten load before bottom, 3-time of load axis melt. iteration2.0 3.52Pressure, kN/m 1.6 2 3.0Pressure, kN/m1.2 2.52.00.8 1.50.4 1 1.0 2 12 0.50 0a) 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 b) 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0Relative distance from load axis Relative distance from load axisFigure 8: Hydraulic and EM pressure on meniscus surface. 1-hydraulic pressure, 2-EM pressure36'
