METHOD FOR MAKING ARTICLES BY FREEZING ON MELT MATERIALS Russian patent published in 2002 - IPC

FIELD: foundry, namely processes for making laminate articles of hard-to-form metals and alloys, including precision articles. SUBSTANCE: method comprises steps of preparing surface of moving mandrel, freezing on its surface melt layer and cooling it; preliminarily freezing on or melting on mandrel surface additional layer of easy-to-melt matter; milling and(or) turning said layer for providing its predetermined dimensions and necessary quality of its surface; cooling mandrel, adding to it upper and lower heat insulation inserts and introducing it from downwards in thermal chamber for freezing on in vacuum or in protective atmosphere; feeding melt from mixer onto mandrel for freezing on; working formed layer until its predetermined thickness and separating it from mandrel due to demounting the last or due to melting additional layer. Method provides possibility for making at superhigh cooling rates directly from melts thin-wall laminate products, articles with capillaries and reinforced articles. EFFECT: enhanced efficiency of method. 4 dwg
