Definitions
- the invention relates to a method and to a device for casting metals, in particular aluminum or one of its alloys, into charge.
- this reserve also called enhancement or "HOT-TOP according to the Anglo-Saxon designation has found its interest in the search for a good surface condition, especially on billets.
- the methods using an enhancement have been particularly developed in the case of multiple flow castings where they allow, with a single level adjustment, to lead the casting into several tens of molds at the same time.
- This process is characterized in that an inert gas pressure is applied to the lower part of the periphery of the riser throughout the duration of the casting.
- the inert gas is believed to prevent the ingress of ambient air at the bottom of the riser.
- the elements are mounted as follows: the lower riser rests on a shoulder which is provided with the upper part of the mold.
- the nuts also contribute to pressing the clamping ring against the lower riser and thus subjecting it to a higher stress the higher the tightening rate of the nuts.
- the clamping ring is provided with a flange which is fixed on a shoulder placed at the upper part of the mold. by means of screws and that said ingot mold is made integral with the base plate by at least four diametrically opposite springs two by two integral with a clamping bar.
- a lower riser-ingot mold-clamping ring assembly is formed which can be separated as a whole from the base plate. This assembly also makes it possible to maintain constant and independent of the tightening of the ingot mold fixing on the base plate the pressure stress exerted on the lower riser.
- this assembly into the device is done simply: it is applied against the base plate and the upper part of the riser by means of a seal and maintains it in this position by means of elastic strips. This shortens the disassembly and reassembly times.
- FIGS. 1 and 3 represent in section along a vertical axis a half-section of the casting device.
- an extension consisting of an upper part (1) connected to a lower part (2) via a seal (3).
- the part (2) is placed overhanging (4) relative to the graphite ring (5) of the mold (6) cooled externally by the coolant fluid from (7a).
- This assembly is held integral by means of a clamping ring (8) and nuts (9) which fix the mold on a base plate (10).
- the bottom of the part (2) is surrounded on its entire periphery by a ring (13) so as to form an annular chamber (11) which is supplied with inert gas via a pipe (12).
- Figure 2 differs from Figure 1 in that the mold is cooled by means of a system (7b) generally called "water jacket •.
- the ring is formed by a portion of the ingot mold which corresponds to a particular embodiment of the invention since this ring can be distinct from the ingot mold.
- the clamping ring (8a) is provided with a flange (14) which is fixed on a shoulder (15) placed at the upper part of the mold (6) by means of screws (16) and said mold is made integral with the base plate (10) by the pressure of at least four springs (17) diametrically opposite two by two and integral with the clamping bar (18).
- Disassembly and reassembly of such a device requires almost 15 times less time than for a device of the prior art.
- the replacement rate of the extensions due to disassembly is practically zero.
- the gas supply line was vented.
- the pipe was connected to a source of dry nitrogen so as to maintain a pressure of 0.024 MPa, while the other casting parameters were kept identical to those of the first test. It was found that the billet obtained during the first test had numerous pits on its surface while that of the second test was completely free.
- the method and the device according to the invention can be applied in particular in multiple ingot mold installations for billet casting with reduced labor and without any risk of adjustment.
