Crystallisation Behaviour and Heat Transfer Phenomenon of Fluoride-free Mould Fluxes for Steel Continuous Casting
… a benchmark. The critical cooling was 7 degree Celsius/s and the shortest incubation time was 15 s at 1000 degree Celsius. Dominant precipitate was Ca2SiO4 at 950 and 1100 degree Celsius with minor Na2CaSi3O8 and Ca2MgSi2O7. Cuspidine was only found at 950 degree Celsius. For fluoride-free mould …
