Preparation of sludge grinders for metallurgical remelting
Waste of the metalworking industry is analyzed from the point of view of their further processing. There is a lack of effective methods of processing and disposal of grinding sludge and, as a consequence, a negative impact on the environment. Existing

The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Biomass Briquettes From Açaí (Euterpe oleracea Mart.) Seeds As A Renewable Energy Alternative
This study evaluates açaí seed briquettes as a sustainable energy source. Characterized by high density of 985.6 km.m−3 and heating value of 19.75 kJ.kg−1, these densified residues reduce industrial reliance on fossil fuels, manage solid waste, and preserve native biomes and reducing pollutant emissions. ABSTRACT In this study, the use of açaí (Euterpe

Influence of annealing temperature of straw briquettes on their density and hardness
The study evaluated the effect of annealing temperature of non-wood, herbaceous ground briquettes on their density, hardness and fracture incidence. The study showed an average density of hay briquettes at 20 °C was 1 256.99 kg·m−3, whereas at 60 °C ...
