FIELD: casting of flat ingots from aluminum alloys. SUBSTANCE: tray has recess in its upper part with central and side zones. Recess is made in the form of part of composite body of revolution cut off by horizontal plane. Central zone is formed by ellipsoid. Its depth is determined by radius amounting to 60-100% of tray width. Width of recess in central zone amounts to 80- 100% of tray width. Side zones of recess are formed by oblique elliptical cylinders with axes inclined towards upper plane of tray. Such form of tray prevents formation of bottom cracks in ingot and ensures uniform cooling of ingot which leads to enhanced quality of ingot. EFFECT: enhanced quality of flat ingots. 1 cl, 3 dwg
