The use of sintered CaO as a refractory material is not uncommon. Refractory material based on lime as the lining of the Bessemer converter was applied for the first time in 1875 in order to carry out desulphuring and dephosphoring of the molten pig iron. Due to interaction of the porous burned CaO with the atmospheric moisture during dead time followed by damage and disintegration of this case...

We justified theoretical and experimental bases of synthesis of new class of highly nanostructured composite nanomaterials based on metal matrix with titanium carbide nanowires as dispersed phase. A new combined method for obtaining of metal iron-based composite materials comprising the powder metallurgy processes and the surface design of the dispersed phase is considered. The following stages...

Titanium alloys have been widely used in many industrial applications. Nevertheless, efforts to improve their properties are continually increasing. One of the most effective routes strength, hardness and wear resistance is create a coating layer on substrates. In current study, stainless steel was selected for in-situ joining creating continuous Ti6Al4V alloy. The process carried out at two di...

The topic of the volume “Early Indian Metallurgy the production of Lead, Silver and Zinc through Three Millennia in North West India”, just published by Archetype Publications in London, discusses archeological data and analytic results, collected in several decades of research in three zinc, lead and silver mines in India. The author of the volume is Paul T Craddock, former Head of Metallurgy ...

In modern cold rolling mills in the steel industry, iron oxide powder is produced as a by-product when used pickling agents are recycled. Further processing of these powders could enable production for various applications metallurgy. For this purpose, new process route with an eco-friendly hydrogen reduction treatment was developed. The able to manufacture variety particles through minor adapt...

Mining and metallurgy have negative consequences for the environment [1-3] and lead to changes in geological [4] and climatic conditions [5]. Mining-metallurgy operations include the extraction, preparing of ores (crushing ore and flotation), processing of concentrates, and the disposal of waste rock and by-products. The main waste in mining and metallurgy are waste rocks, flotation tailings an...
