Improving the quality of iron ore sintering and adding specific components has positive effects on blast furnace productivity. Optimizing basicity in the blast furnace charge is one way to improve all indices of production processes. Adjusting basicity aims to achieve the formation of new phase compounds that are favourable for the metallurgical an...

The study investigates the Portevin–Le Chatelier (PLC) effect in the cold-rolled Al-Mg alloy EN AW-5754. The tensile tests were performed on dog bone specimens at test speeds of 10, 20, and 50 mm/min. Digital image correlation (DIC) and infrared thermography were used to monitor strain rate and temperature changes. The results showed a strong...

One of the new methods of anchoring steel structures is the use of large-scale buckling-restrained braces (BRBs) on the lateral system of this type of structure. This study investigates the behavior of BRBs and compares them with buckling braces. In this study, a two-dimensional frame with four stories and four spans was taken and analyzed in eight...

The changes in pH and conductivity during the rinsing of the pumpkin peel and the biosorption of Cu2+ ions were the subject of this work. The obtained data showed that the pH value of the solutions increased during the rinsing of the biosorbent, as a result of the transfer of H+ ions from the aqueous phase into the structure of the pumpkin peel. An...

To analyze the co-combustion process of coal and biomass in a steam boiler furnace originally designed for pulverized coal combustion, it is crucial first to investigate the dynamic behavior of particles within the aero-mixture channels. Due to differences in material properties and particle size distributions, the behavior of coal and biomass part...
