Abstract

The dissertation thesis is focused on the historical technology of processing of iron ore in La Téne furnaces. The focus of the study is thermal-physical properties. Precisely an examination of the early technologies of iron production. The technology itself has been used since 450 BC. The dissertation thesis contains extensive theoretical and research work, completes a large amount of information contained in historical and current literature. The research part is richly expanded with practical knowledge. In the practical part, experimental smelts are presented, which resulted in practical findings. There were enough of these smelts to determine the efficiency of several types of smelting processes. Several temperature measurement experiments were created and one of them was the first to be performed in this field. When 20 thermal probes were placed in the wall of the furnace and in its center. Subsequently, the chemical properties of the slag were investigated and compared with historical findings. In this case, a striking similarity with the preserved findings was confirmed. Diffraction and fluorescence methods of examination of the samples were used for the analysis. Finally, the iron lupus and its chemical composition were investigated when extensive measurements were made using SEM technology. Lastly, in mainly the theoretical part, the work outlines several other conclusions that could be looked upon and investigated. Mostly, these are different types of methodology of the iron production process and its processing.
