Project 1: Calculation of mold level hunting by unsteady bulging during continuous casting of slab
• Performed structural analysis using Abaqus and Matlab
• Inspected the simulation method by simplified model to expand to the requested model
• Analyzed the result data of Abaqus simulation using Fast Fourier Transform (FFT) on Matlab
• Built Matlab codes to analyze the bulging displacement of solidified shell of a continuous casting's slab
• Communicated actively with the customer to verify the procedure of computational simulation
• Reported progress in customer meeting periodically
Project 2: Designing water channels in a casting mold for an improvement of cooling power
• Performed thermal and structural analysis using Ansys
• Constructed 3D modeling and meshing for three different staves of a blast furnace
• Presented the result in customer meeting
