The problem of biomass combustion and co-combustion is a particularly important aspect many district heating systems, where the use makes it possible to reduce CO2 emissions. present article continuation previous studies behavior mineral matter selected fuels during sintering processes. Three biomasses were studied: wheat straw, barley straw rye as well two coals from Polish mines: bituminous c...

Abstract To investigate the thermodynamic stability and evolution process of inclusions in Al–Ti deoxidized steels, both laboratory experiments calculations were conducted present work. Scanning electron microscope-energy dispersive spectrometer (SEM-EDS) Al 2 O 3 –Ti –TiO phase diagrams used to composition oxide after adding various contents Ti. The results show that TiO x content increases wi...

In this work, the softening and melting (S&M) behaviour whole blast furnace (BF) performance of Newman Blend Lump (NBLL), plant sinter, sinter-NBLL mixture were studied using S&M under load test numerical BF modelling. Both physical chemical interactions between sinter lump confirmed in process. Significant improvements found because interaction. The interaction was examined X-ray/Neutron Compu...

Ferrous metallurgy enterprises continuously fill dumps with steelmaking and blast furnace sludge high zinc content. Sludge occupying significant territories of is not involved in production harms the environment. Since leads to formation deposits furnace, manufacturers cannot involve this sinter processing. In addition, working can lead problems such as decrease iron content sinter, productivit...

The current research on metallurgical remains from scientific excavations in northeast Yunnan the Bronze Age period is insufficient. In order to study smelting technology of north-eastern Yunnan, samples slag and mineral excavated Yubei Di site Dongchuan were examined. Based outcome characterization analysis, a simulation was executed utilizing software Factsage 7.1 generate phase diagram that ...

When preparing lightweight ceramsite using carbide slag, trace amounts of toxic elements are released into the atmosphere due to high-temperature calcination, posing a significant risk environment. The real-time monitoring gases is challenging under laboratory conditions while large quantities ceramsite. Therefore, heating was simulated experimental data and FactSage 7.0 thermochemical database...

Several fluorine-free mold slag compositions have already been established in the literature. In all cases, formation of a crystalline phase exhibiting behavior similar to that cuspidine is emphasized control horizontal heat transfer without influencing lubrication performance for casting peritectic steel grades. contrast, soft steels, glassy solidification required. Herein, different involving...

Abstract Oxidative ladle refining (OLR) is the most widely used process for removal of dissolved Ca and Al in industrial production metallurgical grade silicon (MG-Si). Refining occurs by purging alloy with an oxygen–air mixture at temperatures preferably between 1823 K 1873 K, forming a SiO $$_{2}$$ 2</mm...

Abstract Production of high-quality aluminum products requires an extensive melt treatment process, even more so with the increasing focus on recycling and sustainability. Filtration is a commonly used process segment for removal non-metallic inclusions in aluminum, ceramic foam filters (CFFs) are often as filtration media. In present study, chemical stability phosphate-bonded Al 2 O 3 -based C...

Specific minerals in ash are triggers for fusion during combustion. This study analyses, the first time, link between individual and of pseudo pellets using Optimised Advanced Ash Fusion Test (OAAFT) FactSage modelling. The analysed 20 whose composition spanned a wide range fuels used power generation industry. Varying quantities 4 main were to create pellets; CaO (0–40%), Fe 2 O 3 MgO (0–25%),...
