摘要

This paper reports on the development of a novel technique to control standing surface waves and turbulence. The technique uses external refractory shapes in the continuous casting mold to modify fluid flow and control the surface waves. The method is both economical and flexible as compared to contemporary technologies to solve the problem. Two distinct methods are described based on the placement of the shapes in the mold. Type A shapes are placed nearer the free surface and predominantly work by modifying the upper recirculation region. Type B shapes are placed/deeper in the mold and work by altering the overall fluid flow pattern. Water modeling was carried out on thick slab caster models to understand the behavior of the surface waves. An optimum design of flow control device and its positioning were developed based on the study. Mathematical modeling using commercial fluid flow codes was also used to supplement the experimental results of the process.
