Due to the voids within the sections, this type of charge is characterized by porosity even exceeding 85%. This makes the thermal properties of these elements, expressed by the effective thermal conductivity kef, totally different from the thermal conductivity of steel.}, abstract={The value of the kef coefficient depends on many factors such as: the ratio of the thermal conductivity of steel to that of gas, the structure of the solid matrix and its porosity and the lack of the continuity of the steel phase. The paper describes experimental investigations concerning the measurements of the effective thermal conductivity of a steel sections bundles.}, type={artykuł}, title={The experimental study of the effective thermal conductivity of bundles of rectangular steel sections = Badania eksperymentalne efektywnej przewodności cieplnej wiązek stalowych profili prostokątnych}, keywords={przewodnictwo cieplne, profile stalowe, obróbka cieplna, urządzenia grzejne, effective thermal conductivity, steel sections bundles, heat treatment, hot plate apparatus}, }
