Wire products (continued)
Developments in open-cut mining led to the use of cable belt conveyors requiring wire ropes not previously made in Australia, together with provision of the subsequent steel reinforcing of the conveyor belt.
The plant at Newcastle was largely related to older technology and it was decided to erect a new modern plant at Geelong, Victoria which took its first shipment of rod coils from Port Kembla in 1953. The Geelong plant became a high speed production facility while Newcastle remained the centre of technical developments.
The gradual development of wire producing capacity and technology by BHP had been handled, basically, as separate companies, Rylands, Lysaght Bros. and Co., A.W.R.W. and Bullivants. These were drawn into one company, Australian Wire Industries Pty. Ltd., incorporated in 1959, which resulted in this Company becoming the third or fourth largest wire producer in the world, both by size and product range. From this time, major advances in technology have occurred in the areas of galvanizing, rod preparation and computer process control.
The most significant technological achievement has been the development of the AWI Gas Wiping Process for high speed wire galvanizing. This process revolutionised the manufacture of heavy zinc-coated wires not only in Australia but also in the numerous countries abroad where this technology has since been licensed. It established AWI as a world leader in wire galvanizing. The new process enabled production speed to increase by a factor of three whilst maintaining the quality of the finished product. The enormous speed increases required changes in plant design and further advances have been made with the introduction of vertical pad wiping, again improving plant design over the old inclined withdrawal system, giving ease of operation and flexibility of plant loading. Quenching systems associated with vertical pad wiping now allow a particularly bright finish on this type of wire. The Company is now able to offer a wide range of services covering technology, plant design and commissioning to prospective galvanizing licensees.
A novel development called Fibresteel has made an impact on fibre reinforced concrete technology through a subsidiary, AWI Fibresteel. This Company produces steel fibres with enlarged ends that overcome the problems of inadequate mixing and insufficient bond strength formerly associated with these products. The technology has been licensed to Norway, which is the centre of a large market for fibre reinforced concrete.
Drums and pails
During the war, Rheem made a wide range of products for the allies including boom defence buoys, bombs, smoke containers, shells, aircraft parts, ammunition boxes and water bottles, of the latter, 319,000 without a single leak. Following the war, Rheem returned to the more traditional products and introduced the electric water heater to their range.
Rheem expanded into packaging products and in 1970 it acquired the National Bag Company of Australia. Its main operating company was A. Abrahams & Sons Pty. Ltd. which had begun in 1908 as a sack and bag company and became the national leader in flexible packaging.
