Abstract: Nature and natural systems represent from the beginning of human being magnificent source of both basic raw materials as well as of an inspiration for majority of human driven processes and applications. Biopolymers, representing substances with indispensable role in natural ecosystems, can be listed as the proper example. [..] Read more

Abstract: Self-assembly techniques attracted a lot of interest in recent years due to its ability to form number of periodic surface patterns over large areas. This process is fast, very efficient and cost effective. [..] Read more

Abstract: This paper deals with application of CdTe nanoparticles for analytical determination of Cu(II) and Pb(II) ions by means of laser-induced luminescence spectroscopy. The analytical procedure was optimized for experimental conditions (pH, concentration of nanoparticles and analyte) and then it was utilized for simultaneous determination of both metal ions in water samples.

Abstract: Hydrogen is a well-known chemical element for centuries however its use was highly limited as mainly industrial gas applied in metallurgy, chemical industry, glass industry and others. Within last two decades, hydrogen became significantly more popular thank to its use also as an alternative fuel and source of an energy. [..] Read more

Abstract: The use of technological packages and consequently following our technologic & continuous casting principle, we achieve the shortest start-up times in the industry 4.0. Our modular solution approach ideally meets all technological requirements and customer demands, for both new and existing casters and for the production of carbon, stainless and special AHSS (Advanced High-Strength Steels) steel grades.

Abstract: During the sintering of iron ore in the sintering process, nitrogen oxides (NOx) are produced and discharged with the process off-gas. The reported concentrations of nitrogen oxides expressed as NO2 in sintering off-gas are typically in the range of 300-500 mg/Nm³. [..] Read more

Abstract: During High Carbon Ferromanganese production, the understanding of phases formation is of vital importance since they determine the quality of the overall operations in the furnace. This is also strongly dependent on the chemical composition of the feed. [..] Read more

Abstract: The continuous steel casting (CSC) technology has resulted in an increase in steelworks productivity and made it possible to cast billets of a favourable internal structure. Developing and improving the CSC technology for alloy addition feeding to liquid steel for increasing the purity level or correcting of chemical composition grade seems to be quite an interesting approach for advanced steelmaking process.

Abstract: One model alloy based on Fe-C-Cr and one model alloy based on Fe-C-Ni were studied. Fe-C-Cr based alloy contained carbon of 0.34 wt. [..] Read more

Abstract: The aim of this work is to understand how to manage biomass, either as a stand-alone fuel or in interaction with fossil fuel, and to help define optimal granulometry and fuel mix. A higher proportion of fine-grained particles in sawdust can lead to complications in agglomeration mixture. [..] Read more

Abstract: The potential use of artificial neural networks to determine the solidus temperature for steel based on composition has been investigated. Input data consist of solidus composition and temperatures both from literature and both from measurements. [..] Read more

Abstract: The hot ductility behaviour of a Ti-Nb micro alloyed steel was investigated to evaluate the probability of surface crack formation during the continuous casting process, by performing hot tensile tests. The testing temperatures are ranging from 1100 °C to 700 °C. [..] Read more

Abstract: This work shows the numerical simulation results of liquid steel flow in three strand tundish designed for the continuous bloom casting process. The authors proposed the modification of ladle shroud by expanding-compressing-expanding system at the end of ladle shroud. [..] Read more

Abstract: Continuous steel reheating furnaces belong to high-energy consumption units and an optimization of their operation can thus bring significant economic and ecological benefits. Numerical modelling is one of the tools for an optimization of a design, process parameters and operation control of the furnaces. [..] Read more

Abstract: This paper deals with an experimental determination of surface tension, densities and wetting angles, which were considered for spreading on an alumina substrate, of selected Fe-C-O-X (X = Cr, Ni) alloys. The concerned physico-chemical quantities were determined by a sessile drop method in the temperature interval between liquidus temperature of the given alloy and temperature of 1,600 °C during heating with a rate of 5 °C·min-1.

Abstract: Currently, there is increasing pressure to reduce waste generation and to use it as a secondary raw material. In the framework of this work, there are presented beginning parts of the project plan called "Research of processing of metallurgical waste, materials and by-products from metallurgical and related operations number CZ.02.1.01/0.0/0.0/17_049/0008426“. [..] Read more

Abstract: Model alloys based on Fe-C-Ni and Fe-C-Cr with graded carbon, chromium and nickel content were studied. Two devices with various arrangements and principle of measurement were used and solidus, peritectic transformation and liquidus temperatures were precisely determined for prepared model alloys. [..] Read more

Abstract: The residence time for individual tundish configuration is one of the most important factors of the tundish metallurgy. In the T-type tundishes, it is difficult to set a tundish furniture in order to obtain similar residence time for every strand. [..] Read more

Abstract: The effect of rolling temperature (800-1000°C) - strain accumulation (number of rolling passes: 3÷5) - cooling rate (8.6 – 250C/s) parameters at the High Temperature Thermomechanical Processing (HTMP) on the microstructure, mechanical properties at the room and low temperatures of C-Ni-Nb and C-Ni-V steels intended for the usage as a high- strength material for production of the shelf constructions, strips and other special welded products has been studied. Experiment planning method (EPM) has been used to study the effect of the mentioned above parameters on the mechanical properties. [..] Read more

Abstract: In the paper the results of investigation of drawing method including simple drawing and shear by computer simulation were presented. The simulation in Deform program was performed. [..] Read more
