(University of Pretoria, 1987)Please read the abstract in the section, 00front, of this document
-
(University of Pretoria, 1991)A plug-type oxygen probe containing a magnesia stabilized solid zirconia electrolyte rod, was developed. This oxygen sensor was evaluated in the Fe-Cr-0 system at 1873 K by determining the Raoultian chromium and Henrian ...
-
(University of Pretoria, 1994)The interactions between engineering materials and their environment which give rise to stress corrosion cracking are reviewed and industrial examples from the petrochemical industry are described. In one of the examples, ...

-
(University of Pretoria, 1998)During the past two decades many efforts have been made to increase the control of blast furnace conditions to ensure a homogeneous product. The dissections on blast furnaces by various iron and steel companies in Japan ...
-
(University of Pretoria, 1998)The repair welding of main steam pipelines, which involves the welding of new material onto service-exposed material, are investigated. This paper investigates the literature and experimental work surrounding this subject. ...

(University of Pretoria, 2004)This study focused on the dynamic behaviour of the freeze lining and slag bath, and the interactions between these components in an ilmenite-smelting furnace process. The purpose of the work was to gain a better understanding ...
-
(University of Pretoria, 2004-02-26)Nitrogen-alloyed austenitic stainless steels are becoming increasingly popular, mainly due to their excellent combination of strength and toughness. Nitrogen desorption to the atmosphere during the autogenous welding of ...
-
(University of Pretoria, 2005)The effects SIBX/C10 (or C12) TTC mixtures on flotation response of pyrite, gold and uranium from Anglogold Ashanti’s No 2 Gold Plant feed were investigated. In batch flotation tests where TTC was dosed from aged 1% wt ...

-
(University of Pretoria, 2006)The aim of this study was to arrive at a fundamental understanding of kimberlite weathering and of factors which affect the rate and extent of weathering. Weathering was evaluated by measuring the change in size distribution ...
-
(University of Pretoria, 2006)Mould powders are synthetic slags that contain mixtures of silica (SiO2), lime (CaO), sodium oxide (Na2O), fluorspar (CaF2), and carbon (C). When heated to elevated temperatures these powders liquefy and float on the liquid ...
-
(University of Pretoria, 2006-05-16)A study was carried out to improve the flotation selectivity between galena and sphalerite during the flotation of a Cu-Pb-Zn sulphide composite ore from the Rosh Pinah Mine (Namibia). Xanthate collectors were found to be ...
-
Susceptibility of service exposed creep resistant materials to reheat cracking during repair welding (University of Pretoria, 2006-05-18)Please read the abstract in the section front of this document
-
(University of Pretoria, 2006-06-20)Extensive research has been done over the years and has contributed quite a lot to the development of 3CR12 stainless steel. Nevertheless, there is still much to be understood about the behaviour of this steel during its ...
