-
(Springer, 2023-01)The opening of a furnace tap-hole with an oxygen lance is a complex phenomenon that is not well understood in a quantitative way. By means of a case study, the effect of lancing on flow in and around the tap-hole area at ...
-
(MDPI, 2022-10-31)Chromium alloying of weld metal is usually accomplished via weld wire. This is done because chromium has a high affinity for oxygen and is therefore not easily transferred across the arc. The formation chromium (VI) is one ...
-
(MDPI, 2022-05-11)Flux formulations are specified to target chemical and physico-chemical parameters. Chemical parameters set flux element transfer behaviours and weld metal oxygen contents. Physicochemical parameters such as slag viscosity, ...
-
(MDPI, 2022-12-15)The influence of primary cooling and rebound temperature at C–Mn slab corner surfaces during continuous casting on ferrite film transformation and AlN precipitation was investigated. Laboratory simulations included primary ...
-
(Elsevier, 2022)Thin-walled Al-Si alloy precision casting components are used for various applications due to their excellent castability, corrosion resistance as well as high strength to weight ratio. It is very difficult to achieve all ...
-
(Wiley, 2022-05)Please abstract in the article.
-
(Springer, 2022-12)Please read abstract in the article.
-
(Springer, 2022-04)Please read abstract in the article.
-
(Springer, 2022-04)Boltzmann-type sigmoidal equations to model the tensile strain hardening and flow stress behavior of a metastable AISI 301LN austenitic stainless steel subjected to prior cold deformation have been developed. This model ...
-
(Springer, 2022-06)Please read abstract in the article.
-
(MDPI, 2022-04)The submerged arc furnace (SAF) has become the equipment of choice to produce manganese ferro-alloy. Furnace operators aim to reduce the cost of production by better understanding the role played by the various raw materials ...
-
(Southern African Institute of Mining and Metallurgy, 2022-12)The CSIR-Ti process employs lithiothermic reduction of titanium tetrachloride feedstock to produce titanium sponge. The product is therefore contaminated by a range of lithium and chloride species. In this study we examine ...
-
(Southern African Institute of Mining and Metallurgy, 2022-07)Ferritic stainless steel is utilized to fabricate automotive exhaust systems using a ferritic weld metal. Ductility of the weld metal is higher if its microstructure contains a significant proportion of equiaxed grains. ...
-
(Southern African Institute of Mining and Metallurgy, 2022-07)The aim of this investigation was to determine whether the composition of a shielded-metal arc-welding electrode coating affected the low-temperature impact toughness of austenitic stainless-steel weld metal. It is ...
-
(IGI Global, 2022)Additive manufacturing is a popular emerging technology of producing parts directly from digital models. This technology has presented benefits such as freedom of design, the ability to customise, and shortened process ...
-
(Springer, 2022-03)Traditionally, pyrometallurgical reactors are lined on the inside with refractory materials. Some of the high-temperature phases are aggressive towards the furnace lining, requiring periodic repair or replacement of the ...
-
(University of Pretoria, 2022)Manganese is an important raw material in many industries, such as the steel, non-ferrous and battery industries. Manganese ores are typically mined and are then fed to submerged arc furnaces where a manganese ferroalloy, ...
-
(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 ...
-
(University of Pretoria, 2023-07-27)Incorporating multi-component, multi-phase, high-temperature, complex chemical equilibrium calculations into multiphysics and process models can provide valuable insights into industrial processes and equipment that current ...
