METHOD OF MAKING PLATES Russian patent published in 1994 - IPC

Abstract RU 2010670 C1

FIELD: casting production. SUBSTANCE: method of casting plates, for example of silicium, comprises steps of forming a liquid film of an initial material on a liquid substrate in a bath; simultaneous cooling of the substrate from downwards and the film from upwards till a temperature less, than material crystallization temperature at heating up lateral walls of the bath till temperature more, than the material crystallization temperature; providing contact of a seed with the melt film in its central zone with subsequent separation of the plate to upstairs with the aid of the seed. EFFECT: enhanced efficiency. 1 cl, 7 dwg
