Claims
1. Apparatus for the treatment of molten metal with a particulate treatment agent and a gas, comprising a vessel for holding molten metal, a rotary device for breaking up particulate treatment agent and gas within molten metal, and for dispersing particulate treatment agent and gas within molten metal within the vessel and means for supplying the particulate treatment agent and gas to the rotary device, wherein the rotary device comprises a hollow shaft having a rotor with an axial opening fixed to the discharge end thereof, said rotor comprising an annular plate with a plurality of radially mounted, upwardly directed blades projecting from the top face of the annular plate and a plurality of radially mounted downwardly directed blades projecting from the bottom face of the annular plate.
2. An apparatus according to Claim 1 wherein a further annular plate is fixed below the radially mounted blades that project downwardly from the said annular plate, whereby the particulate treatment agent and gas are discharged between the annular plates.
3. An apparatus according to Claim 1 or 2 wherein the vessel is an aluminum melting or holding furnace and the rotary device is mounted within the furnace with the axis of the hollow shaft at an angle to the horizontal of about 20-40°.
4. An apparatus according to Claim 1, 2 or 3 installed in a furnace having a capacity of about 10- 150 tons. 12
5. An apparatus according to any one of Claims 1-4 wherein the annular plate has 3-12 downwardly directed blades and 3-12 upwardly directed blades.
6. An apparatus according to Claim 5 having six blades on said bottom face and six blades on said top face.
7. An apparatus according to any one of Claims 1-6 wherein the outer ends of the radially mounted blades do not project beyond the outer periphery of the annular plate or plates.
8. A rotary device for the treatment of molten metal comprising a hollow shaft and a rotor with an axial opening fixed to the discharge end thereof, said rotor comprising an upper annular plate and a lower annular plate with a plurality of radially mounted, upwardly directed blades projecting from the top face of the upper annular plate and a plurality of radially mounted blades fixed between said upper and lower annular plates .
9. A process for the treatment of molten metal with a particulate treatment agent and a gas which comprises providing a rotary device comprising a hollow shaft having a discharge end and an annular rotor attached to the shaft, the rotor having a plurality of radially mounted upwardly directed blades and a plurality of radially mounted downwardly directed blades, immersing the rotary device in molten metal contained in a vessel, rotating the device while feeding particulate treatment agent and gas down through the hollow shaft whereby the particulate 13
treatment agent and gas enter the molten metal beneath the rotor and are broken into droplets and finer particles and dispersed within the molten metal by the shearing action of the downwardly directed blades and further mixing the molten metal by the action of the upwardly directed blades whereby clouds of bubbles formed by action of the downwardly directed blades are dispersed within the molten metal .
10. A process according to Claim 9 wherein the annular rotor includes a further annular plate fixed below the radially mounted blades that project downwardly from said annular plate and the particulate treatment agent and gas are delivered to the molten metal through segment-shaped cavities formed between the annular plates and radially mounted blades.
11. A process according to Claim 9 or 10 wherein the rotor is operated within the furnace with the axis of the hollow shaft at an angle to the horizontal of about 20-40° .
12. A process according to Claim 11 wherein the rotor is operated within the furnace such that all parts of the rotor are located at least 30 cm from any interior surface of the furnace.
13. A process according to any one of Claims 9-12 wherein the molten metal is aluminum or an alloy thereof and the particulate treatment agent is a salt flux.
14. A process according to Claim 13 wherein the salt flux is molten by the point at which it enters the molten aluminum.
