METAL CASTING METHOD AND APPARATUS, AND METAL MATERIAL MANUFACTURING METHOD AND APPARATUS

摘要

A casting method includes the steps of cooling a molten metal to form a metal slurry containing a solid phase, cooling the metal slurry to form a solid metal material and heating the metal material to a semi-melted metal materia l and supplying it into a mold. A casting apparatus includes a first device fo r cooling a molten metal to form a metal slurry containing a solid phase and a second device for cooling the metal slurry to form a solid metal material. T he metal material is then heated to a semi-melted state and the resultant metal material is poured into a mold. A method for manufacturing a metal material being heated to a semi-melted state and then supplied into a mold, includes the steps of cooling a molten metal to form a metal slurry containing a solid phase and cooling the metal slurry to form a solid metal material. An apparatus fo r manufacturing a metal material being heated to a semi-melted state and then supplied into a mold, includes a first device for cooling a molten metal to form a metal slurry containing a solid phase and a second device for cooling the slurry to form a solid metal material.
