Magnesia refractory dryout : managing the risk of hydration

Steenkamp, Joalet Dalene; Kotze, H.; Meyer, J.G.; Barnard, J. (Southern African Institute of Mining and Metallurgy, 2011-06)

In 2002 the commissioning of an ilmenite smelter on the North Coast of South Africa was extended by three months due to the failure and subsequent replacement of the magnesia-based refractory lining. The lining failed ...
Optimizing yield of metallic zinc tapped from a zinc smelter by studying factors causing zinc losses to dross

De Meyer, A.; Steenkamp, Joalet Dalene (Southern African Institute of Mining and Metallurgy, 2010-04)

Zincor experienced significant losses of metallic zinc to dross during the melting of zinc cathode plates. In this study five factors affecting the formation of dross are identified from literature. Dross from both the ...
Thermal conductivity of solidified manganese-bearing slags : a preliminary investigation

Steenkamp, Joalet Dalene; Tangstad, M.; Pistorius, Petrus Christiaan (Southern African Institute of Mining and Metallurgy, 2011)

The thermal conductivity of slag is an important parameter in the design of furnace-containment systems based on freeze-lining technology. Literature indicates that the crystal content of a slag has a significant influence ...
Wear mechanisms of carbon-base refractory materials in SiMn tap-holes : Part II : In situ observation of chemical reactions

Steenkamp, Joalet Dalene; Pistorius, Petrus Christiaan; Tangstad, M. (Springer, 2015-04)

The purpose of the study presented here is to determine to what extent chemical reactions between carbon-based refractory and slag or metal in the tap-hole of a SiMn furnace can contribute to wear of tap-hole refractory. ...
Wear mechanisms of carbon-based refractory materials in silicomanganese tap holes : Part I : Equilibrium calculations and slag and refractory characterization

Steenkamp, Joalet Dalene; Pistorius, Petrus Christiaan; Tangstad, M. (Springer, 2015-04)

Silicomanganese (SiMn) as an alloy supplies silicon and manganese to the steelmaking industry. It is produced through carbothermic reduction in a submerged arc furnace. The slag and metal are typically tapped through a ...
