New furnace to increase DMS
Powders output
BATEMAN has been contracted by DMS Powders, a division of Samancor
Ltd, to replace its existing furnace with a new, 2 t induction furnace
that will increase the output of ferrosilicon by 40 %, and to upgrade
the feed system to the furnace.
The contract covers the removal of the existing furnace,
generator and all associated equipment, and replacing it with a new
Electrotherm medium-frequency induction furnace. ABB South Africa is
managing the project on behalf of the client.
Although the new furnace is similar in dimensions to the old furnace,
the fact that it operates between 300 and 350 Hz means that the production
capacity will be greatly improved. Also, homogenisation of the melt
will be facilitated, as will start-up of the furnace from a cold state
with no heel required.
The contract follows BATEMAN's signing of a representative
agreement with Electrotherm (India) Ltd, designer and supplier of the
latest technology in induction melting, smelting, heating and re-heating.
Over 800 furnaces have to date been supplied worldwide by Electrotherm,
and this contract increases the number of Electrotherm furnaces in South
Africa to four after only two years of marketing in South Africa. The
furnaces installed locally have capacities of 1 t, 3 t, 4,5 t and 5
t, although furnaces of up to 30 t are available.
The post-taphole services provided by BATEMAN have
traditionally covered the design and supply of processes and equipment
in secondary metallurgy, such as the solidification of molten metals
and slags, from atomisation through granulation to lump and ingot formation.
These processes are enhanced by the design and supply of hydraulic and
electro/mechanical taphole equipment, ladle tilters and the latest designs
in granulation de-watering equipment.
The agreement with Electrotherm has resulted
in a significant increase in the portfolio of post-taphole services
and technology offered by BATEMAN. As a result, induction furnaces,
induction-refining furnaces, AC and DC ladle-refining furnaces, and
induction heating and refining converters are now offered. Also available
are Electrotherm's open-arc furnaces, ranging from 5 t to 150 t, and
AC sub-arc furnaces up to 15 MVA (which supplement BATEMAN's range of
larger furnaces), DRI kilns, technology for furnace charge pre-heating
and the continuous casting of billets, and rolling mills.
