Abstract Traditional mold fluxes contain a large quantity of fluorides, which will corrode continuous casting equipment and pollute the environment. Non-fluorination of mold fluxes has been an objective requirement of green metallurgy. Although significant progresses has been achieved in the relevant research, the unstable metallurgical performances of fluorine-free mold fluxes limit their industrial applications, and the factors influencing the metallurgical properties remain undetermined. This paper reviews the worldwide efforts in exploring the metallurgical properties of fluorine-free mold fluxes in recent years, including melting properties, viscosity properties and crystallization properties, and analyzes relevant research results of various physical and chemical properties. It also contains a summary of current industrial applications of fluorine-free mold fluxes and a prospective discussion on the future trends, in which further investigations on the influence of composition and structure of slag on its performance from the aspects of molecular dynamics and thermodynamics are suggested. This review is expected to provide some guidance for the development of fluorine-free mold fluxes.

Key words： mold fluxes fluorine-free metallurgical properties continuous casting
