Using  principle  of  minimum  total  potential  energy  approach  in conjunction  with  Rayleigh-Ritz  method,  the  electro-thermo- mechanical  axial  buckling  behavior  of  piezoelectric  polymeric cylindrical  shell  reinforced  with  double-walled  boron-nitride nanotube  (DWBNNT)  is  investigated. Coupling  between  electrical and mechanical  fields  are  considered  according  to  ...

The blast-furnace process consists of a large number of processes that are physicochemical, thermal and mechanical interconnected processes. In addition to main processes consisting of iron oxides reduction, pig iron and slag melt creation, also realised are fuel combustion, gas flow, charge and melt flow, dissociation and other reactions in the solid and liquid phases. Inputs to the blast-furn...

Conductive fillers, such as graphite particles (GP), steel slags (SS), and ground granulated blast furnace slag (GGBS) have been widely utilized in designing electrically conductive cementitious composites (ECCC) for various applications, including traffic detection, structural health monitoring (SHM), pavement deicing. Owing to the complex working field, a comprehensive understanding of role t...

Boron nitride nanotubes (BNNTs) have many application areas thanks to their superior properties such as thermal and electrical insulation, resistance oxidation, high hydrophobicity, hydrogen storage capacity, well biocompatible properties. Therefore, new synthesis methods are being searched for BNNT with increasing interest in recent years. In this study, purity yield BNNTs were synthesized usi...

M. Szega, W. Stanek Silesian University of Technology, Gliwice, Poland L. Blacha Silesian University of Technology, Katowice, Poland The reduction of energy consumption in the blast furnace is still the subject of investigations using mathematical modelling of a blast furnace plant. Theoretical-empirical hybrid models of a blast furnace and its equipment have been presented. This model is built...

The purpose of this study was to evaluate the performance of porous vegetation concrete block made from blast furnace slag cement containing industrial by-products such as blast furnace slag aggregate and powder. The blocks were tested for void ratio, compressive strength and freeze-thaw resistance to determine the optimal mixing ratio for the porous vegetation block. An economic analysis of th...

grate bar is an industrial part which is used in the indurating furnace of an iron ore pelletizing plant. steel part ofthe grate bars are expected to have high resistance to atmospheric oxidation because of its contact with hot gases(up to 920 °c) during the normal operation of the process. in this study, different samples from several sections ofused grate bars with apparent defects were selec...

Sn-3.7wt.%Ag-0.9wt.%Zn alloy was directionally solidified upward under different conditions, with different growth rates (V = 3.38 220.12 μm/s) at a constant temperature gradient (G = 4.33 K/mm) and with different temperature gradients (G = 4.33 -12.41 K/mm) at a constant growth rate (V = 11.52 μm/s) by using a Bridgman-type directional solidification furnace. The microstructure was observed to...
