Slag/refractory and metal/refractory interactions during

Higher quality refractory materials result in increased costs, thus a balance needs to be struck between costs, quality of the steel, and throughput. Refractory properties play a vital role in their behaviour with slag and steel. These properties are both physical and chemical in nature, and extensive research has been conducted to understand the various mechanisms at play in the systems

Wear Mechanisms of Carbon-Based Refractory Materials in

refractory materials was tested in two ways: by exam-ining the slag–refractory interface after exposure to elevated temperature and by observation in situ in a wettability test. Wetting of carbon refractory by slag can be used to indie the occurrence of reaction because slag should not wet the carbon refractory if no reaction was to occur; however, if the slag was to react with the

Centre for Pyrometallurgy | Article | University of Pretoria

The Centre for Pyrometallurgy within the Department of Materials Science and Metallurgical Engineering was officially launched by Mr Godfrey Gomwe, Executive Director Anglo American South Africa on Monday 30 May 2011. With the establishment of the Anglo American Chair in Pyrometallurgy within this department in 2009, the concept of the formation of a Centre for Pyrometallurgy originated.
