Controlling the Thermal and Rheological Properties of Silicate Glasses for Development of Advanced Mold Flux Systems

Development of the advanced mold flux is always mandatory to enhance both quality and productivity continuous casting steels. Especially, increasing demands for high alloy steels production speed reveals serious contradiction between two principal functions flux: lubrication controlling heat transfer. In order overcome this problematic needs, some innovative research activities are being carried out. MAE (Mixed Alkali Effect) has been examined in alumino-borosilicate-based system stabilize alkali cation aluminum association, which enables chemically stable glassy film during Non-Newtonian fluxes could be developed by addition Si3N4 or SiC due increase stiffness polymeric structure, would beneficial satisfy contradictory requirements viscosity at top surface wall. Some ideas transfer without deteriorating have dispersion nano-size metallic particles modification prenucleation motif. All these trials closely related with glass science engineering. Therefore, it should highly collaborative metallurgy society further development functional systems.
