Abstract (en)
In order to prevent crack formation in a hot top (2, 3), made from refractory material, surmounting an ingot mould (1) in a casting of aluminium and of its alloys in the form of plates or billets, a compression prestress is applied to the said hot top before the casting, perpendicular to the casting axis independent of the flanging forces on the ingot mould and obtained by controlled peripheral hooping (binding, banding). <IMAGE>
