摘要：

The successful application of the repair and prevention of LD converters refractories technique called Slag Splashing requires a close control of the slag physicochemical properties (basicity, viscosity and surface tension), as well as suitable selection of operational parameters and geometric configurations. In this paper, a Slag Splashing process cold simulation is carried out, focusing on a case study of an LD converter from Ternium Brasil Company, located in Rio de Janeiro. The cold physical simulation showed the effect of solids fraction and viscosity on slag projection intensity, evidencing how the coating is affected. Finally, computational thermodynamics shows the evolution of the phases and viscosity during N-2 blowing, allowing correlating results of the cold model with industrial practice.
