LOST-WAX METHOD ASSOCIATED WITH PIEZOCRYSTALLISATION AND A DEVICE FOR CARRYING OUT SAID METHOD |
摘要 |
The inventive casting method consists in pressing a melt from a metal receiver into the cavity of a shaped investment mould at a temperature which is greater than a liquidus line and a pressure which enables a maximum splash-free liquid metal flow and which is increasable along with the melt crystallisation to a pressure sufficient for filling the mould to a quantity of a casting shrinkage volume. The inventive device for carrying out said method comprises a metal receiver embodied in the form of a removable cylinder, which is coated inside thereof and provided with an annular flange, and a container which, comprises the shaped investment mould and whose hollow throat is provided with a removable fire-resistant sleeve. The flange is mounted in such a way that the internal diameter thereof mates with the external diameter of the sleeve, wherein the internal diameter of the flange is smaller than the internal diameter of the cylinder.
