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...

The combustion process of TiO2- 2Mg- C and 3TiO2-4Al-3C systems in a tubular furnace was investigated. TiC has been synthesized by the magnesiothermic reaction from a mixture of compacted powders of TiO2, Mg and charcoal as starting materials in the presence and absence of NaCl. The effects of temperature, pressure, and the stoichiometry ratio in the reactio...

The spectra were recorded by a FTIR spectrometer (Brucker Equinox 55) with a MCT detector at an optical resolution of 2 cm-1 and 2 level zero-filling. For the accelerated ageing tests the quartz reaction chamber with ZnSe optic windows was placed in the sample compartment of the spectrometer. The chamber was equipped with an electric furnace enabling heating in the broad temperature range (to 9...

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...

We applied a recently developed single particle mass spectrometer to analyze the elemental composition of individual aerosol particles and applied the technique to study the kinetics of thermal decomposition of metal nitrate aerosols (aluminum, calcium, silver, and strontium). Such decomposition processes on the industrial scale is known as spray pyrolysis and is a common method for making meta...
