研究了熔体调节剂（MC）在半固态条件下生产高质量DC方坯和板坯中的应用。在该技术中，液态金属被连续地供给到双螺杆熔体调节装置中，在该双螺杆熔体调节装置中，液态金属或半固态浆料经受高剪切速率，然后被连续地输送到DC铸造机中。本文研究了变形铝合金半固态MC铸造的可行性，探索了液态温度以下MC铸造的可能性。这种想法可能会挑战通常在液相线温度以上进行的常规DC铸造。
The application of Melt Conditioner (MC) for production of high-quality DC billets and slabs at semisolid state is examined. In this technique, liquid metal is continuously fed into a twin-screw melt conditioning device, where the liquid metal or semisolid slurry is subjected to high shear rate, and then delivered continuously into a DC caster. In this paper, the feasibility of MCDC of a wrought aluminium alloy in the semi solid state has been investigated and the possibility of DC casting by MC technique below the liquidus temperature as a novel idea was explored. This idea may challenge the conventional DC casting which is normally performed above liquidus temperature.
