-
(Southern African Institute of Mining and Metallurgy, 2019-10)The mining industry of the 21st century needs a new kind of leader as certain leadership styles and most leadership models currently employed in the world, and also in South Africa, are not sustainable. This article ...
-
(Southern African Institute of Mining and Metallurgy, 2021-02)Accretions often form in furnaces when slag and charge materials attach to the refractory wall and build up over time. Accretion formation is usually unwanted because it reduces the working volume of the reactor and ...
-
(Southern African Institute of Mining and Metallurgy, 2017-07)Extraction of nickel from either laterite or sulphide ores involves various complex hydrometallurgical processes, the final step of which is often electrowinning to produce pure nickel metal. Methods to investigate, monitor, ...
-
(Maney, 2009-12)Hulamin Rolled Products (Ltd) developed a high Mn and Si containing alloy, EN 4017 as a scrap consuming alloy from the waste generated in producing their range of clad products for brazing of inter alia automotive heat ...
-
(Southern African Institute of Mining and Metallurgy, 2013-04)Ti-64, which accounts for more than 50% of the worldwide titanium tonnage, has found commercial importance in industries requiring components with high specific strength and resistance to corrosion. Investment casting ...
-
(MDPI, 2022-05)Nickel alloying of carbon steel is used to enhance steel strength and toughness. Nickel alloying of the weld metal via solid weld wire presents several difficulties as highlighted previously, such as work hardening of ...
-
(MDPI, 2022-02-24)Al assisted alloying of carbon steel in Submerged Arc Welding (SAW) by Al-Cr-Ti-Cu unconstrained metal powders is applied. A base case without metal powder additions is compared to two metal powder addition schedules, ...
-
(MDPI, 2022-11-02)Unconstrained metal powders of chromium and nickel, in combination with aluminium, were used in the submerged arc welding (SAW) process to simplify weld metal alloying. Unconstrained metal powders refer to non-alloyed ...
-
(MDPI, 2021-10-01)The element transfer of Ti from molten flux to the weld metal is limited to less than 310 ppm Ti in the submerged arc welding of carbon steel. This limitation is due to the high oxygen partial pressure prevailing at the ...
-
(MDPI, 2022-08-25)The application of cobalt and aluminium powders in unconstrained format, not as metal powder in tubular wire nor as pre-alloyed powder, is used in this work to simplify weld metal alloying. The objective of this study ...
-
(Iron and Steel Institute of Japan, 2018-02-15)Please read abstract in the article.
-
(IOP Publishing, 2019-09-09)In South Africa, forged wheels for rail cars are imported but cast wheels are manufactured locally, although recent developments indicate that forged wheels will in future be manufactured locally. The forged wheels are ...
-
(MDPI Publishing, 2018-06-22)Global industrial adoption of laser-based powder bed fusion (LPBF) technology is still limited by the production speed, the size of the build envelope, and therefore the maximum part size that can be produced. The cost of ...
-
(Southern African Institute of Mining and Metallurgy, 2021-04)Additive manufacturing can be used to produce complex and custom geometries, consolidating different parts into one, which in turn reduces the required number of assemblies and allows distributed manufacturing with short ...
-
(Southern African Institute of Mining and Metallurgy, 2020-06)Denel Dynamics, a South African armaments development and manufacturing company, is interested in introducing additive manufacturing (AM) in the fabrication of missile components. The practicality of using AM for industrial ...
-
(MDPI, 2023-02)Unconstrained metal powders of Cu, Cr, Ni and Al were applied to submerged arc welding (SAW) to clarify the chemical behaviour of copper in this modified SAW process. Aluminium metal is avoided in SAWbecause it is easily ...
-
(MDPI, 2022-02-01)In submerged arc welding (SAW) of chromium containing steels, the chromium in the weld metal is usually sourced from weld wire. Manufacturing of precise weld wire compositions for alloying of the weld metal is expensive. ...
-
(Southern African Institute of Mining and Metallurgy, 2015-03)In April 2013 a 48 MVA submerged arc furnace producing silicomanganese was excavated in South Africa. Since the high shell temperatures recorded in the tap-hole area resulted in the furnace being switched out for ...
-
(Taylor and Francis, 2023-06-15)This paper presents the numerical and experimental results of the mechanical and microstructural properties of liquefied petroleum gas cylinders from local sources. The tensile strength, burst and fracture toughness of the ...
-
(Elsevier, 2023-12)The use of alternative low polycyclic aromatic hydrocarbon (PAH) binders in taphole clays is essential due to health and environmental concerns associated with PAHs. Binders that could potentially substitute for ...
