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. [..]

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.

DOI: https://doi.org/10.37904/metal.2019.669, 95-100
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.

DOI: https://doi.org/10.37904/metal.2019.676, 101-106
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.

DOI: https://doi.org/10.37904/metal.2019.800, 117-122
Abstract:
Production of innovative types of steel and other metallic materials requires the composition to contain, in addition to iron, other chemical elements that influence desired properties of the alloy. Alloy additions are mainly introduced due to the use of appropriate ferroalloys in the production process. [..]
