Abstract
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.

In an abrasive slab casting device wherein a molten abrasive oxide material is cast between a plurality of generally vertically arranged chilling plates having opposing pairs of surfaces shaped to form a narrow abrasive receiving recess between each pair of plates, said plates being supported so they are normally free to move towards and away from each other, the improvement which comprises
- plate driving means in front of a casting position moveable at a predetermined velocity and operative on a group of plates, while generally vertically arranged, to push them toward, through and beyond the casting position,
- plate restraining means beyond said casting position having a surface which is moving at less than said predetermined velocity and which acts to restrain said group of plates so that adjacent pairs of plates are pressed together through and beyond said casting position to prevent leakage of molten abrasive from the narrow recesses, and
- plate separating means beyond the restraining means operative to separate adjacent plates, and thereby to discharge from the narrow recess the solidified abrasive oxide material formed therebetween.
