title: Effects of Na2CO3 on properties of low fluoride content mould flux for thin slab continuous casting.
abstract: To reduce fluorine pollution, partial fluoride could be replaced by Na2C03 in mould flux for continuous casting. The properties including melting temperature, viscosity fluidity, surface tension and A1203 inclusion adsorption of low fluoride content mould flux with addition of Na2C03 for thin slab casting were studied. The results showed that with the increase in Na2C03 content, melting temperature, viscosity and viscous activation energy of mould flux decreased obviously, fluidity increased, surface tension changed little, and A1203 inclusion adsorption of mould flux increased. The Na2C03 could play effective role when its content was less than 9%. The results would play a guiding role in designing of low fluoride content mould flux for thin slab continuous casting.
