In this work, the effect of slag phase on dephosphorization in BOF (basic oxygen furnace) is explored by industrial practical experiments. The research results show that final rate related to rather than basicity and T.Fe content slag. correlation between ability proportion liquid (phase B) phosphorus-containing solid solution A) much higher RO (MgO·FeO, MnO·FeO) C). phosphorous partition fitti...

In this study, the early age hydration kinetics of BOF slag is investigated. Isothermal calorimetry and in-situ X-ray diffraction (XRD) are used to examine effects K3-citrate concentration nanosilica addition on reactivity. The results reveal that brownmillerite most reactive phase during first 24 h hydration. controlled by dosage, reaction strongly accelerated with highly concentrated solution...

Abstract This work shows an innovative application for electric arc furnace (EAF) slag: its use as a filler nitrile butadiene rubber (NBR). Composites with various EAF slag contents were tested. It was found that the polymer matrix significantly reduces leaching of (determined according to standard CEN-EN 12457-2) incorporated in NBR. The processability characteristics determined by rheometric ...

Vanadium extraction methods were developed for iron-vanadium-phosphorus (FeV-P) melts derived from processing of V-bearing titanomagnetites and steel slags. Studies on phase relationships of V slags were carried out to provide important understanding of the extraction processes. Phase relationship in vanadiferous slag was investigated experimentally at 1573K, 1673K and 1773K, for the compositio...

The control of slag foam that is produced during the Basic Oxygen Furnace (BOF) process has been subject significant research. behaviour foams complex. Hence, in dynamic BOF challenging. Acoustic analysis one most promising methods for indirect measurement height. This paper reviews different studies on fundamental acoustics liquid and various acoustic related to determining height process. Stu...

This study investigates the potential to recover iron and chromium from a chromium-bearing carbon steel Electric Arc Furnace (EAF) slag. slag contains indeed about 30 wt.% Fe 2.5 Cr. However, minerals are intergrown at small scale (<100 µm) mostly contained in spinel phases which makes separation challenging. Several methods including Mössbauer spectroscopy, X-ray Diffraction, Scanning Elect...
