An experimental study of slag foaming
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Slag foaming occurs in several pyrometallurgical processes. These processes include
steelmaking in basic oxygen steelmaking furnaces and electric arc furnaces (EAF) as well
as various non-ferrous ...
Modelling and control of an autogenous mill using a state space methodology and neural networks
(Stellenbosch : Stellenbosch University, 2002-12)
ENGLISH ABSTRACT: Metallurgical processes are often high dimensional and non-linear making them
difficult to understand, model and control. Whereas the human eye has extensively
been used in discerning temporal patterns ...
The development of a simulative hybrid model for optimising the production of a high-carbon ferromanganese furnace.
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: A project was initially commenced for optimising the production output at a specific
high-carbon ferromanganese furnace. Since operational difficulties were experienced
in this furnace and with a lack ...
The control of calcium and magnesium in a base metal sulphate leach solution
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: This thesis investigates the control of calcium and magnesium in a base metal
sulphate leach solution containing nickel and cobalt. The presence of calcium and
magnesium in the hydrometallurgical ...
The development of a one-dimensional quasi-steady state model for the desulphurisation process at Saldanha Steel
(Stellenbosch : University of Stellenbosch, 2003-04)
ENGLISH ABSTRACT: The pneumatic injection of reagent powder into molten iron has become
the preferred way to carry out iron and steel desulphurisation. It is
therefore essential to not only understand the thermodynamic ...
Acoustic monitoring of DC placma arcs
(Stellenbosch : Stellenbosch University, 2008-03)
ENGLISH ABSTRACT: The arc, generated between the cathode and slag in a dc electric arc furnace
(EAF), constitutes the principal source of thermal energy in the furnace.
Steady state melting conditions rely on efficient ...
