| titleOfInvention | Method and apparatus for the treatment of molten metals |
| abstract | ABSTRACT METHOD AND APPARATUS FOR THE TREATMENT OF MOLTEN METALS Apparatus for the treatment of molten metal with a particulate treatment agent and a gas comprises a vessel, a rotary device for dispersing particulate treatment agent and a gas in molten metal contained in the vessel and means for supplying the particulate treatment agent and gas to the rotary device. The rotary device comprises a hollow shaft having a discharge end and a hollow rotor attached to the shaft, the rotor having a plurality of vanes each extending from the shaft or from a location adjacent the shaft towards the periphery of the rotor so that the hollow interior of the rotor is divided into a plurality of compartments, each compartment having an inlet adjacent the shaft and an outlet adjacent the periphery of the rotor, and the rotor has means for passing the particulate treatment agent and gas from the discharge end of the hollow shaft of the device to the compartments. In a preferred embodiment the discharge end of the shaft opens into a manifold in the rotor and the inlets for the compartments are in the wall of the manifold. For relatively fine particles the means for supplying the particulate treatment agent and gas to the rotary device may be a hopper fitted with gas injection nozzles, or an apparatus in which the particulate treatment agent is fluidised by the gas to produce a dispersion and which is connected by a pipe to the bore of the shaft of the rotary device. For larger particles the means for supplying the particulate treatment agent and gas to the rotary device may be a hopper having a sealed top having a closable inlet for the particles of treatment agent, and an aperture in its base communicating with a tube located inside the bore of the shaft of the rotary device, the sidewall of the hopper adjacent the base having at least one series of apertures spaced apart around its perimeter, each aperture having projecting through it to the inside of the hopper a sliding member, and the tube having one or more apertures therein for the introduction of gas. |
