The aim of this paper is to define and select stable zones in the off-gas duct an ore-thermal furnace using a mathematical model. This needed increase effectiveness exhaust gas composition control metallurgical silicon production. Methods. goals study were achieved by means computational fluid dynamics. A model with water-cooled roof as well comprising steel passes sliding shutter was developed...

The archaeometallurgy of copper have been pioneer technologies in ancient Iran and goes back to about ten thousand years ago in Iranian Plateau [1, 2]. The Haft Tappeh Middle Elamite Site is located in Southwest Iran and have been an important city belonging to early phase of Middle Elamite period (14th century BCE) [3, 4]. Based on various metallurgical evidences found in archaeological excava...

Geometallurgical mapping is a new team-based approach that documents variability within an orebody and quantifies the impact of geology (host rocks, alteration and structure) and mineralogy on grinding, metallurgical response and metal recovery processes. The quantitative, spatially constrained database that results can be readily integrated into 3-D block models and mine planning activities. T...

The main production route for cast iron and steel is through the blast furnace. silicon content in an important indicator of thermal condition a High contents indicate increase furnace's input and, some cases, may excess coke reactor. As costs predominate iron, tighter control therefore has economic advantages. objective this article was to design artificial neural network predict hot metal, va...

Most of the iron in the world is produced using a blast furnace process, which has iron ore (iron oxides) and coke as its raw materials. When pellets are used in a blast furnace, the iron burden material is charged in the form of pellets and fine, iron-rich by-products are charged typically in the form of cold-bonded briquettes at the top of the blast furnace. Coke is the primary fuel and reduc...

B. Gajdzik, The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland The publication presents the most recent results of research conducted in metallurgical enterprises which build Polish metallurgical sector. Three main areas of restructuring were tested, that is repair restructuring, development restructuring and adaptation restructuring. For each t...

Recent excavations made by University of Lecce in Piazzetta Epulione and Piazza Castromediano (Lecce) have produced structures and artifacts related to metal-working. Most of the evidence dates back to the Roman period; traces of metallurgical activity can also be traced to the periods preceding and following the Roman period. Iron slags and semi-finished objects have been found in Piazzetta Ep...

We report a multipurpose furnace designed for studies using synchrotron radiation on polycrystalline materials, namely, metals, ceramics, and (semi)crystalline polymers. The furnace has been designed to carry out three-dimensional (3D) x-ray diffraction measurements but can also be used for other types of synchrotron radiation research. The furnace has a very low thermal gradient across the spe...
