shape casting process, melt-conditioned high-pressure die-casting (MC-HPDC) was developed. In this process, liquid metal was conditioned under intensively forced convection provided by melt conditioning with advanced shear technology (MCAST) unit before being transferred to a conventional cold chamber high-pressure die-casting (HPDC) machine for shape casting. The effect of melt conditioning......

and liquidus temperature in the PbO-ZnO-CaO-SiO2-"Fe2O3" system, with the mass ratios of CaO/SiO2=1-1.6 and Fe/SiO2= 1.3-1.7, and 40% PbO and 8% ZnO, were carried out between 1273 and 1573 K. Slags were... between 1373 and 1473 K. The Ca/Pb silicate and magnetoplumbite phases are partially formed by an incongruent reaction. The experimental and thermodynamical results showed that the liquidus increased......
