Plain strain deformation trials were carried out on samples of pipeline steels at 1473 K, 1673 K and 1723 respectively. The inclusions in the solid steel different temperatures semi-solid was studied. composition changed from 60.62%Al2O3–16.10%CaO–10.27%MgO–13.01%CaS before to 60.59%Al2O3–13.03%CaO–12.74%MgO–13.63%CaS, 59.69%Al2O3–7.04%CaO–11.51%MgO–21.76%CaS, 68.26%Al2O3–22.56%CaO–6.68%MgO–2.5...

Abstract Al 4 C 3 particles form during the primary production of aluminum via molten salt electrolysis due to carbon solubility and direct contact between bath, metal, anodes. Additional may melt processing through carbonaceous materials. As a result their small size similar density aluminum, removal carbide can be challenging. If not removed, carbides produce inclusion defects or poor surface...

Thermal conversion of automotive shredder residue (ASR) using indirect fluidized bed gasification was conducted in the Chalmers semi-industrial 2–4-MWth gasifier. The material consisted olivine that activated through deposition biomass ash prior to a 13-day exposure ASR. interactions between and ASR were investigated XRD, SEM-EDS, thermodynamic modeling. iron (Fe) onto particles noted, this is ...

The modification of basic oxygen furnace (BOF) slag by adding silica can improve the properties BOF for applications in cement industry. rapid dissolution is essential to hot modification. In this work, behavior molten CaO-SiO2-Fe2O3-MgO-MnO system as synthetic was investigated using traditional rotating cylinder technique. Effects rotation speed, temperature, immersion time, and basicity on we...

In blast furnaces it is desirable for the burden to hold a lumpy packed structure at as high temperature possible. The computational thermodynamic software FactSage (version 7.2, Thermfact/CRCT, Montreal, Canada and GTT-Technologies, Aachen, Germany) was used here study softening behavior of furnace pellets. effects main slag-forming components (SiO2, MgO, CaO Al2O3) on liquid formation were es...

Cord steel is used for making tire frames and wire saws cutting silicon wafers. The diameter of mainstream has been developed to be lower than 100 μm. size deformation ability inclusions are very important the breaking rate cord during drawing process. In order improve in steel, alkali metal oxide was added into molten so as obtain good, plastic, low-melting-point inclusions. Mass fractions 0.3...

In the Selective Crystallization and Phase Separation (SCPS) process, manganese oxide is used as an additive to promote precipitation of perovskite. However, influence on liquid domain perovskite primary phase field still unclear. present work, liquid-perovskite equilibrium with addition 0–15 wt% Mn 3 O 4 was experimentally determined using a high-temperature isothermal equilibration-quenching ...

Al2O3 substrate is widely used as a lining refractory material throughout the blast furnace (BF) process. Accordingly, erosion of by molten slag has negative influence on running cost and smooth operation BFs. The effect behavior BF primary containing FeO-CaO-SiO2-MgO-Al2O3 was fundamentally investigated using high-temperature contact angle method FactSage thermodynamic software based compositi...

CeO2 can be applied to refining slag minimize the size of inclusions, speed up deoxidization process, and adsorb Al2O3 inclusions. The impact through which content affects slag’s melting efficiency is still uncertain. thermal analyzer was used measure thermogravimetric analysis (TG) differential scanning calorimetry (DSC) curves process. According study results, with increase in content, temper...

Abstract With the raw materials for ironmaking are becoming increasingly complex, more accurate control of blast furnace operation is essential to reduce energy cost and CO 2 emission. CaO–SiO –Al O 3 –MgO a basic system slag in which CaO MgO mainly come from flux, SiO Al materials. Effect material composition on phase equilibrium can be described by pseudo-ternary (CaO + MgO)–SiO at fixed MgO/...
