Continuous casting mold powder is a silicate - containing functional materials for a wide range of flux and reinforcing materials . Protection of slag in the mold plays to prevent secondary oxidation of liquid steel , insulation , absorption inclusions, uniform heat transfer , lubrication slab role is to promote the development of continuous casting technology to ensure the continuous casting process anterograde and slab quality one of the critical materials . Now, with the continuous improvement of the continuous casting casting speed , slab species continue to expand , the slab quality requirements rising , a variety of physical and chemical properties of mold powder day of the continuous casting process anterograde and slab quality and more important , to become one of the limiting factors for the future development of continuous casting technology . Firstly continuous casting mold powder composition and performance relationship , mainly including various trace components , alkali metal oxides , melting speed regulation etc. such as melting temperature , melting rate , viscosity , crystallization temperature performance discussed ; scene mold powder melting point and viscosity experimental determination of the results of the analysis ; then focus on the heat transfer performance of the protective slag , analysis of the impact of the protective slag thermal diffusivity , interfacial thermal resistance factor. Finally, a simple forecast the future direction of development of the protective slag , that is, to meet the high - speed casting , suitable for the production of ultra-low carbon steel , suitable for the needs of environmental protection . This paper aims to draw some conclusions, including the protective slag composition on its properties and characteristics of the various Fluxes conclusion , through the study of the composition and performance of the protective slag of the relationship between hope these conclusions is composed of more reasonable Fluxes provide some basis for the development and continuous casting technology to improve .
