The process of metallurgical equipment information space is complex and diverse, including multi-level spatial information or spatial process factor. How to divide the metallurgical equipment information space, to plan its communication path intelligently and to enhance the level of intelligent equipment has become one of the metallurgical equipment systems’ problems needing to be resolved. Aim...

Bauxite Metallurgical Residue (BR) is a highly alkaline and very fine-grained by-product of the Bayer process for alumina production. Its huge global annual production has resulted in increasing accumulation BR, causing deposition problems serious environmental issues. RM contains oxides salts main elements Fe, Al, Ca, Na, Si, Ti, rare earths—REEs (Sc, Nd, Y, La, Ce, Ds)—many which have been ca...

INTRODUCTION To improve the fracture resistance of nickel-titanium (NiTi) files, manufacturers have introduced new alloys and developed new manufacturing processes for the fabrication of NiTi files. This study aimed to examine the phase transformation behavior and microstructure of NiTi instruments from a novel controlled memory NiTi wire (CM wire). METHODS Instruments of EndoSequence (ES), P...

The problem of parasitic residual deposition on the passivation layer in electroless deposition process is studied in this paper. The characterization analysis tools involved are focused ion beam (FIB), scanning electron microscopy (SEM), electron dispersive Xray (EDX) and metallurgical interface analysis. Samples were identified as either good or bad prior to the characterization process via a...

The noxious potential of metallurgical tailings from the Ag/Pb/Zn/Cu mining district of Sta. María de la Paz (Mexico) is ascertained via the chemical characterization of slag material. Batch experiments using various extraction solutions (e.g. natural rainwater, water rich in humic substances, ammonium nitrate solution) revealed information on the dissolution behaviour of the elements Fe, Mn, N...

This work illustrates the production and characterization of metallurgical coke from Duduguru coal, Obi local Government Area Nasarawa State, Nigeria. The analytical assessment properties such as proximate analysis, elemental composition, calorific value are very important to know coking qualities coal. analysis showed that moisture content, ash volatile matter, fixed carbon values coal are; 1....
