The scrap-based electric arc furnace process is expected to capture a significant share of the steel market in future due its potential for reducing environmental impacts through recycling. However, managing impurities, particularly phosphorus, remains challenge. This study aims develop machine learning model estimate phosphorus content at end based on input parameters. Data were collected over one year from plant, focusing parameters such as chemical composition and weight scrap, volume...
In hot metal desulphurisation (HMD) the slag will hold removed sulphur. However, iron that is lost when skimmed off, accounts for highest costs of HMD process. These losses are lower has a viscosity, which can be achieved by changing composition. A basicity decreases viscosity slag, but also lowers its sulphur removal capacity, therefore optimisation necessary. this study, optimal composition investigated, considering both capacity and losses. part I theory discussed in II validated with...
For a successful implementation of newly proposed silicon-based latent heat thermal energy storage systems, proper ceramic materials that could withstand contact heating with molten silicon at temperatures much higher than its melting point need to be developed. In this regard, non-wetting behavior and low reactivity are the main criteria determining applicability as potential crucible material for long-term ultrahigh temperature silicon. work, wetting hexagonal boron nitride (h-BN) by was...
Gold is a significant revenue source for custom copper smelters facing profitability challenges due to low treatment and refining charges, stricter regulations, rising costs. also often blended with concentrates, but precise recovery rates from smelting processes are poorly documented despite gold critical economic importance. This paper aims provide the first comprehensive estimates of first-pass across various operational units within sulfide concentrate processing flowsheet. It evaluates...
In the pyrometallurgical process of secondary lead recycling, a desulfurising agent, such as Na2CO3 is added to minimise emissions sulfur into atmosphere, while silica introduced smelter fluxing material. Subsequently, significant amount Na2O and SiO2 remains in downstream reverberatory furnace blast slags. However, there limited understanding thermodynamic behaviour silicate-based slags rich Na2O, posing challenges accurately determining optimal condition for targeted metal recovery final...

Abstract A pilot scale, silicomanganese alloy production campaign was performed in a 440 kVA, single phase electric furnace order to establish an overview of the minor- and trace element contents process input raw materials their distribution resulting primary secondary products. Samples in-going (manganese ore, coke, quartzite, high carbon ferromanganese slag) out-going products (silicomanganese alloy, slag, dust) were analyzed by inductively coupled plasma mass spectrometry. The 51...
The present study focused on reinforcing Al–Si–Cu alloy with a cast iron insert and using Zn– xAl–3Si–0·5Mg (wt-) intermediate alloys by the joining technique to take advantage of lightness stiffness hybrid structure. experimental set-up consisted coating hot dipping method followed immersing coated into Al melt allowing system cool down room temperature. quality Al–Fe joints in terms morphology, thickness, chemistry microhardness was evaluated as function composition immersion time melt....
The oxidation of silicon (Si) has been extensively investigated over the past 50 years. Yet, an understanding mechanism and rate liquid Si in atmospheres containing water vapor, is lacking. effect vapor on process particular importance industrial, metallurgical production processing silicon, as a significant amount silica fume generated under such conditions. generation due to active metal tapping, refining, casting steps—a major occupational health safety challenge for producers. In this...
A complete thermodynamic description of the Na 2 O–FeO–Fe O 3 –Al system was conducted based on critical evaluation and optimization available properties phase diagram data.

The optimal hot metal desulphurisation (HMD) slag is defined as a with sufficient sulphur removal capacity and low apparent viscosity (ηslag) which leads to iron losses. In part I of this study, the fundamentals behind were discussed. these are explored by Monte Carlo simulation, based on FactSage calculations, plant data analysis melting point measurements slag. Furthermore, applicability knowing composition for an industrial HMD

Abstract Knowledge of thermodynamics and phase equilibria oxidic materials is crucial for advancement in the field ceramics glass. With development computational thermodynamics, predicting diagrams chemical reactions multicomponent systems has become possible. However, there are still plenty oxides, thermodynamic properties which have not been identified due to challenges conducting experiments. Therefore, a key modeling would be develop universal model that can used estimate oxides with...
