The effect of 2CaO·SiO2 (C2S) addition on the melt formation temperatures and microstructures iron ore sinters has been elucidated from perspective silico-ferrite calcium aluminum (SFCA) in bonding phases as SFCA improve strength sinter. samples used this study are categorized into two: “C + S” “C2S”. contain CaO SiO2 components, while “C2S” intermediate compounds SiO2, i.e., C2S. Both have an ...

Abstract The main indicators of the iron ore quality are content iron, silica, phosphorus and other components. It is ascertained that depends on its grain-size composition. article proves when crushing 16-0 mm fraction to 5-0 mm, Fe reclassified by sizes due liberation both martite hematite at this grain size. To reduce energy consumption during grinding, it recommended install high pressure g...

The article analyzes the production and sales results of enterprises mining metallurgical complex Ukraine (hereinafter MMC) in 2020, first quarter for four months 2021, as well preconditions that developed 2019. It was determined MMC 2019 were worst entire period existence independent Ukraine. factors ineffective work this period. In situation aggravated by COVID-19 pandemic. Steel declined, wh...

Oxygen content in aluminium alloys Al-3Fe or Al-8Fe-lZr (wt%) maked from air atomized powders by a sinter-forging

Sintering is a complex industrial process that applies heat to fine particles of iron ore and other materials to produce sinter, a solidified porous material used in blast furnaces. The sintering process needs to be carefully adjusted, so that the combustion zone reaches the bottom of the material just before the discharge end. This is known as the burn-through point. Many different parameters ...

The article presents results of the research on use chars produced during pyrolysis residual biomass as a substitutional fuel in iron ore sintering process. Such an approach allows to implement circular economy and industrial symbiosis steel branches. effect substitution conventional coke breeze used final sinter quality emission was examined. With regard productivity, consumption, properties i...

Iron ore sintering is a predominant process for fine iron and its concentrate to be applied in the blast furnace process. However, produces negative impact on environment. One of effective ways reduce greenhouse gas emissions from use CO 2 -neutral biomaterials fuel needs this technology. Walnut shells (WNS) are promising raw material such substitute. Herein, effect pyrolyzed WNS with constant ...
