Study on Melting Properties of CaO-Al2O3-SiO2-MgO System Calcium Aluminate Flux
Melting properties of CaO-Al2O3-SiO2-MgO system calcium aluminate (CA) flux were investigated through orthogonal design on three levels of four factors (content of CaO,Al2O3,SiO2 and MgO,respectively) to explore a reasonable chemical composition of CA flux.Results show that the softening temperature (Ts),hemispherical temperature (Th) and flowing temperature (Tf) of CA flux are influenced by the flux components in the order of SiO2 > MgO > CaO > Al2O3.The optimal chemical composition of flux is 3 wt.% SiO2,6~12 wt.% MgO,45 wt.% CaO and 40 wt.% Al2O3.Additionally,mineralogy composition analysis of flux clinker shows that the CA flux is mainly composed of 12CaO·7Al2O3 (C12A7),3CaO·Al2O3 (C3A) and 6CaO·4Al2O3·MgO·SiO2 (C6A4MS,Q phase).
