The melting performance of high alumina blast furnace slags

With a view to understanding the performance of blast furnace slag with high Al2O3 content, effects w(MgO)/w(Al2O3), w(CaO)/w(SiO2), and w(Al2O3) on melting (melting characteristic temperature heat) content were investigated by differential scanning calorimeter (DSC) method. Experimental results indicate that end (Tend) for almost all slags has no obvious change increase w(CaO)/w(SiO2) will raise Tend slag. When (w(MgO)/w(Al2O3), R, are high, onset (Tonset) increases any variables. is low, Tonset decreases w(Al2O3). within scope this study these factors lead heat.
