Abstract: Electric arc furnaces (EAF), especially of foundry class, operating with a long-term technological period, are characterized by a high level of energy loss. Intensification of heat and mass transfer in steelmaking bath by pneumatic or electromagnetic (EMS) stirring contributes to increase energy efficiency of the EAF. [..] Read more

Abstract: The paper analyses the magnitude of foundry stresses in cast iron and steel castings. For the analysis of foundry stresses, a new methodology for measuring the level of residua! stresses on modified test bodies was proposed to test the propensity of iron alloys to hot-cracks and cold-cracks.

Abstract: The paper deals with the possibility of thermodynamic analysis of CaO - SiO2 - Al2O3 - MgO slag system for optimizing of steel desulphurization in a ladle. From the point of view of reducing the sulphur content in steel, the chemical composition of the slag plays a crucial role which affects a critical thermodynamic parameter of the slag, such as the liquidus temperature of the slag, the amount of solid phases in slag at range of refining temperatures, respectively the effective viscosity of slag and CaO saturation in slag.

Abstract: During last decades, extracting value-added products from industrial waste materials became a crucial research area because it not only provides valuable products but also mitigates the problem with disposal of these wastes and, at the same time, it facilitates saving natural resources. Various dense media for industrial separations are based on a variety of raw materials or commercially manufactured materials, such as clay, quartz, slate, galena, magnetite or ferrosilicon.

Abstract: The specific heat capacity of substances is one of the determining thermal technical properties of technical materials such as steels influencing their heating or cooling. Knowledge of their values is necessary for accurate calculations of processes such as solidification during casting in the form of continuously cast billets or ingots and during heating before forming processes or during heat treatment of finished products.

Abstract: Titanium aluminide alloys are considered to be attractive materials for aerospace and automotive high-temperature applications due to their high specific strength, creep resistance, and heat resistance. However, their brittleness makes it difficult to manufacture complex-shaped components of these alloys using conventional processes making additive manufacturing a promising way to produce titanium aluminide parts.
