The blade portion of the electrode is then rolled after it has been cast. The blade portion may be rolled into at least two different thicknesses. In one embodiment the metal is lead or lead alloy and the method relates to the forming of a lead or lead alloy anode.
Description
AN ELECTRODE AND A METHOD FOR FORMING AN ELECTRODE
BACKGROUND OF THE INVENTION
THIS invention relates to an electrode and to a method for forming an electrode, typically a lead alloy anode.
Previously, electrodes were cast from a metal and had to be formed with a thicker blade for rigidity and corrosion resistance as cast metal, such as cast lead, typically corrodes faster than rolled metal.
Later developments have seen the manufacturing of the electrode by casting the header of the electrode and rolling the blade with the blade then bei'ng welded to the head.
However, this is relatively more difficult to manufacture.
The invention seeks to address this.

BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 shows an example plant for manufacturing electrodes according to one aspect;
Figure 2 shows a schematic representation of an electrode formed using the plant of Figure 1; and Figure 3 shows a schematic representation of an electrode after it has been cast but before it has been rolled.
DESCRIPTION OF PREFERRED EMBODIMENTS
An embodiment will be described with reference to the forming of lead alloy anodes but it wiil be appreciated that the methodology could be used with other metal or metal alloy electrodes such as the forming of aluminium cathodes to name but one example.
Referring to the accompanying Figures, a metal or metal alloy is passed into a melting pot 10.
The melting pot is heated to a temperature range for example between 300 C and 600 C, depending on the alloy, and the alloy is melted.
A second metal such as a copper bar, for example, is placed into a mould 12. Copper is used worldwide and is the preferred metal. The length shape and thickness of the copper hanger bar is determined by the weight and size of the anode to be formed.

DESCRIPTION OF PREFERRED EMBODIMENTS
An embodiment will be described with reference to the forming of lead alloy anodes but it wiil be appreciated that the methodology could be used with other metal or metal alloy electrodes such as the forming of aluminium cathodes to name but one example.
Referring to the accompanying Figures, a metal or metal alloy is passed into a melting pot 10.
The melting pot is heated to a temperature range for example between 300 C and 600 C, depending on the alloy, and the alloy is melted.
A second metal such as a copper bar, for example, is placed into a mould 12. Copper is used worldwide and is the preferred metal. The length shape and thickness of the copper hanger bar is determined by the weight and size of the anode to be formed.
-4-Under the force of gravity melted lead alloy passes from the melting pot through connecting pipe 14 into the bottom of the mould 12, rising up and covering the copper bar.
Because the melted lead alloy is gravity fed from the bottom of the mould, this helps eliminate air pockets and impurities floating on the matter metal.
Once the metal has cooled sufficiently, it is placed in a cooling tank 16, if necessary.
Certain alloys do not require cooling in which case the cooling tank 16 will not be used.
The metal is moved from the mould 12 to the cooling tank 16 using an overhead crawl beam and hook contraption 18.
Thus the first step of casting the metal or the metal alloy in the mould is complete and the metal is now moved to a mould 20 in the form of a horizontal mould.
After the anode has been cast but before it is rolled its shape is as depicted in Figure 3 with the thickness of the blade 32 being a thickness "A".
The moiald typically includes guide rollers 22 and compression rollers 24 which have a flywheel compression drive 26. As the cast metal passes through the horizontal rollers the cast metal is rolled and the shape of the cast metal changes.
If required, the electrode can be rolled and cross-rolled to spread in the molecules evenly.
After rolling the width of the blade 32 is as shown in Figure 2 with thickness "B" and "C" being less than the thickness "A" in Figure 3.
The thickness of the casting before rolling will be ascertained by the required finished thickness and will typically need to be compressed by between about 30% and 70% depending on the alloy in use. In the illustrated embodiment this amounted to about 3mm.
In any event, the compression rollers 24 typically start in a more open position to allow the part of the electrode with the copper insert to pass through towards the pit 28.
Once the copper portion has passed through to a predetermined position, the compression rollers begin closing to compress the portion of the metal or metal alloy behind the copper portion.
In this manner, the copper header bar 30 and blade 32 are integrally formed without requiring the welding of the header to the blade.
The header is typically not rolled at all since it is not immersed in the solution and is not subject to corrosion.
The electrode is,then trimmed and fettled ready for dispatch.
It will be appreciated that where the electrode corrodes quicker at solution level, the electrode can be rolled thicker from the header to approximately 30mm below the solution level while the remainder of the blade can be rolled as required. An example of this can be seen in Figure 2.
Thus the electrode will have three different thicknesses. One example of these different thicknesses is illustrated in the accompanying drawing.
In any event, the method is suitable for any metal or metal alloy electrode and will give required electrical conductivity and mechanical strength of rolled metal or metal alloy but with a simpler and less costly manufacturing process than previous designs.
In addition, the methodology allows existing lead anodes to be recast and rolled to provide the improved structure.
