摘要: Thin cast sheets having an excellent quality are obtained by continuous casting in which a semi-solidified metal slurry is fed from a continuous production device of the semi-solidified metal slurry through a discharge nozzle provided with means for heating the nozzle itself into a twin roll type continuous strip caster, at where the slurry is rapidly quenched and solidified to fine a structure and dispersion of precipitate.
