Numerical Analysis of Spray Water Flow in Secondary Cooling of Continuous Casting Process of Steel using MPS Method

Abstract

In continuous casting process of steel, evenness of solidification is one of the most important issues of quality of the steel. Molten steel is solidified at water-cooled mold and followed by secondary cooling by water spray. To analyze the phenomenon of width direction’s unevenness of solidification, it is important to visualize the flow pattern of spray water. Computational fluid dynamics is useful but grid based methods for example FVM, FDM, and FEM are not appropriate because of complex free surfaces. So, particle based method called MPS was applied. One of the characteristic patterns of roll arrangement was modeled, and spray water flow was calculated. As a result, it has been found that there are dripping water between roller bearings and steel plate and overflowed water on rolls. The accuracy of the numerical model has been verified by water model experiment.
