Abstract
A distributor device for use in aluminium casting includes a rigid, substantially bowl-shaped receptacle (2) of a refractory material having a base member (4) and a peripheral wall (6) that extends upwards from the base. The receptacle has an inlet opening (8) towards the upper end thereof and a pair of outlet openings (14) towards the base thereof. The device is constructed and arranged such that, in use, molten aluminium poured into the distributor device through the inlet opening (8) is redirected by the distributor device and flows outwards into the mould through the outlet openings (14).
Claims24
A distributor device for use in an aluminium casting operation to direct the flow of molten aluminium into a mould, the distributor device including a rigid, substantially bowl-shaped receptacle (2) of a refractory material having a base member (4) and a peripheral wall (6) that extends upwards from the base member, said receptacle having an inlet opening (8) towards the upper end thereof and at least one outlet opening (14) towards the base thereof, the device being constructed and arranged such that, in use, molten aluminium poured into the distributor device through the inlet opening (8) is redirected by the distributor device and flows outwards into the mould through said at least one outlet opening (14).
A distributor device according to any one of the preceding claims, wherein the peripheral wall (6) includes two side wall members (10) and two end wall members (12).
A distributor device according to any one of the preceding claims, wherein the base member (4) includes a raised flow deflector (16).
A distributor device according to any one of the preceding claims, wherein the peripheral wall (6) is inclined outwards.
A distributor device according to any one of the preceding claims, including a heating element for pre-heating the device.
A distributor device according to any one of the preceding claims, including a support structure (24,26).
A distributor device according to any one of the preceding claims, including a porous element (38) constructed and arranged such that, in use, molten aluminium poured into the distributor device flows through said porous element.
A distributor device for use in aluminium casting, the distributor device (36) including a rigid, substantially bowl-shaped receptacle (2) having an inlet opening at the top and at least one outlet opening (14) towards the base thereof, and an inner liner (38) including a substantially bowl-shaped mesh of woven material that fits into and is supported by said rigid receptacle (2), the arrangement being such that molten aluminium poured into the distributor device through the inlet opening flows through the mesh of woven material before exiting through the at least one outlet opening (14).
An aluminium casting installation including a mould (20), a delivery device (28,30) for delivering molten aluminium into the mould and a distributor device (2) according to any one of the preceding claims, the distributor device (2) being mounted below the delivery device (28,30) and above the mould (20), the installation being constructed and arranged such that, in use, molten aluminium is poured from the delivery device into the mould through the distributor device.
