Title
Materials Processing : Studies on Characteristics of Mold Level Fluctuation in Thin Slab Casting
윤욱석U Sok Yoon,김성연Seong Yeon Kim
Abstract
The characteristics of mold level fluctuation were investigated using FFT(Fast Fourier Transformation) analysis of mold level and measuring strand bulging in thin slab casting. The special frequency of periodic mold level fluctuation, which was amplified with casting time and sometimes made breakout of solidified shell, was coincided with that of strand bulging and pinch roll speed. The unsteady bulging of strand was the main cause of this kind of mold level fluctuation.
