BATEMAN rebuilds Transalloys No. 3 Furnace in 105
days
Highveld Steel and Vanadium Corporation commissioned
its Transalloys Furnace No. 3 at Witbank, South Africa in October
2005, following a successful BATEMAN mini-rebuild that took just 105
days.
The lump sum turnkey (LSTK) contract awarded to BATEMAN to rebuild
the furnace included the supply of a new furnace foundation, shell
and refractory lining, shell hearth-cooling system, operator tapping
platform and related tapping equipment, such as a rail-mounted clay
gun and tap drill arrangement and two control stations. A fume-extraction
system was installed to manage fumes generated during the tapping
process, in compliance with Transalloys' overall commitment to environmental
conservation. In addition, the existing electrode-clamping device
was replaced with the more advanced BATEMAN model.
In the rebuild, the existing rotary furnace was replaced with a stationary,
dual tap-hole furnace, and radial cooling system. The latter is able
to provide an average air flow of 15 m/s, thereby efficiently cooling
the furnace base. The entire tapping floor was rebuilt and two new
tapping launders fitted.
The BATEMAN electrode slipping / clamping device was conveniently
adapted to operate within the envelope of the replaced slipping device,
with only minor structural modification to the support structures
of the main building. The device was also modified to accommodate
selected components of the replaced slipping device, saving on both
time and cost. The adaptability of the clamping device has proved
to be a key element in the successful installation of the device.
Installation was constrained by existing major building structural
steelwork, as well as the lack of available work space. However, despite
the constraints and extremely tight schedule, Bateman still managed
to successfully complete the project within 105 days.
