Definitions

  • the present invention relates to the continuous production
  • Mol ten aluminium alloy is used in a variety of production methods, for example in continuous casting and to supply a "Conform"
  • the present invention seeks to provide a method and apparatus for the production of molten alloy metals in controllable quant i t ies .
  • the invention provides an
  • the apparatus includes a feedback control system whi ch determines the rate of production of the alloy and adjusts the amount of alloying metal being supplied.
  • a valve controls the flow of the mol ten basic metal from the furnace and the val ve assembly forms part of the receiving means and the alloying metal is introduced into the basic metal flowing through the valve, and together they are supplied to an alloying chamber where the alloy is temporarily contained to allow the alloying elements to diffuse uniformly through the basic molten metal.
  • the alloying metal(s) can be held in a "master" alloy of the basic metal with high coneentration(s) of the alloying metal(s). According to another aspect of the invention there is provi ded a method of producing molten metal alloy comprising
  • Figure 1 is a schematic section through an apparatus according to the preferred embodiment of the i nvent ion.
  • Figure 2 is a combination of a part of the diagram of Figure 1 and a block schematic diagram of a control circuit for the apparatus of Figure 1. DESCRIPTION OF PREFERRED EMBODIMENTS
  • Figure 1 shows a preferred em bodiment of the invention, wherein a molten al uminium alloy is produced and supplied to a "Conform" extruding apparatus.
  • a furnace 1 is connected through a mixing and flow control valve 2 to an alloying chamber 3, which val ve has an upper port 2a.
  • a conveying apparatus 4 is arranged to supply a molten alloy from the alloying cham ber 3 into a Conform apparatus 5.
  • a sluice gate 6 controls run-off from the alloying chamber 3 to a run-off 7.
  • aluminium A is melted in the f urnace 1 and run into the mixing control valve 2.
  • the "Master Alloy” rod B in rod form is also -supplied into the mixing control valve 2 through port 2a, to be melted by the molten al uminium A.
  • the molten al l oy mixture runs into the alloying cham ber 3 where the alloying metals in the " Master Alloy” diffuse throughout the basic al uminium metal to produce a consistent alloy of desired composition.
  • the "Master Alloy” rod B is of known alloy composition and is cont i nuously fed into the mixing control val ve 2 to produce the des i red output alloy.
  • the feeding of the "Master Alloy" B is controlled by a pair of rollers 10.
  • the speed, of rotation of the rollers 10 is controlled by a control circuit 20.
  • a sensor 8 detects the area of the extrusion output from the Conform extruder 5 to provide an area input A to control circuit 20 and a speed sensor 9 provi des an input V related to the speed of product ion of the extrusio n material.
  • the control ci rcuit 20 is supplied with input data giving the required alloy composi t ion and the composition of the master alloy B which is to be added to the basic molten alum inium A. From the data supplied the cont rol circuit 20 controls the feed rolls 10 to provide the master al loy rod at an appropriate rate to produce the desired output alloy..
  • valve 2 At termination of extrusion with a particular alloy the valve 2 is closed shutting off flow of aluminium from the furnace 1 and the master alloy B is no longer supplied. The remaining, 5 relatively small quantity of alloy in the mixing control valve 2 and alloying chamber 3 is run-off through run-off 7 by opening the sluice gate 6. It will be appreciated that only a relatively small volume of alloy is run-off. Production of an alloy of differing composition can then begin, with the appropriate data being provided
  • the control circuit 20 is supplied with data such as:- (1) extrusion speed V, 5 ' (2) extrusion cross section area A, which together with the extrusion speed V enables it to calculate the volume or weight per minute flowing through the valve,
  • control system would reduce the master alloy rod speed to 0.98 m/min to maintain the correct alloy composi t ion.
