Effects of NaF on Mould Flux Properties for Thin Slab Continuous Casting

Abstract:

Using industrial material and synthetic test instrument for the physical characteristics of slag, the effects of NaF on melting temperature, viscosity, fluidity, surface tension and Al2O3 inclusion adsorption of mould flux for thin slab continuous casting were studied. The results showed that with the increase of NaF content, melting temperature, viscosity and surface tension decreased obviously, and fluidity and Al2O3 inclusion adsorption increased. The effects of basicity on properties should be taken into account. NaF could play effective role when its content was less than 9%. The results would play a guiding role in designing of mould flux for thin slab continuous casting.
