<p>An automatic progressively or continuously operative mold assembly for chilling a material which melts in excess of 1700.degree.C and forming quickly a fine crystalline solid material therefrom by depositing said material in a molten state in the relatively thin spaces between a plurality of relatively thick heat sink plates maintained tightly contiguous as they are moved sequentially through and beyond a first mold filling or discharging station, and then moved very rapidly sequentially through a second mold emptying or discharging station in which the relatively thick heat sink plates are maintained spaced apart to discharge therefrom the fine crystalline solid material adhered thereto.</p> |
