of CaO and Al2O3 in all inclusions were close to the composition of the phase Ca12Al14O33 and the contents of CaO and Al2O3 in the slags were close to the composition of the phase Ca3Al2O6 in the binary phase diagram of CaO-Al2O3.The forth sub project set out to study the effect of vacuum degassing time on non-metallic inclusions.Properties of ShKh15 steel remelted in vacuum - NASA/ADSRemelting in vacuum (10 -3 -10 -4 mm Hg) practically eliminates nonmetallic inclusions and gases from the steel.This decontamination decreases the susceptibility of the steel to blue brittleness and increases its wearability.Nucleation,Growth,Transport,and Entrapment of Jul 27,2013 Nonmetallic inclusions in vacuum#0183;Inclusion-related phenomena in the continuous casting mold region are shown in Fig.2,and the inclusion-related phenomena are summarized in Table I.The current project is to quantify the contribution of these phenomena on inclusions in final products using models combining the macroscale fluid flow models and nano- and microscale inclusion models.

Apr 05,2016 Nonmetallic inclusions in vacuum#0183;The nonmetallic phase consists mainly of small inclusions of alumocalcium silicate.In cold-rolled sheet (thickness 1.2 mm),the nonmetallic phase consists of a few very small globules (23 m).The results are compared with the composition of the nonmetallic phase in analogous steel with no vacuum treatment.Non-metallic inclusions in steel [SubsTech]May 31,2012 Nonmetallic inclusions in vacuum#0183;The non-metallic phases containing more than one compound (eg.different oxides,oxide+sulfide) are called complex non-metallic inclusions (spinels,silicates,oxysulfides,carbonitrides).Despite of small content of non-metallic inclusions in steel (0.01-0.02%) they exert significant effect on the steel properties such as:Non-metallic inclusions : FMA Mechatronic Solutions AGNon-metallic inclusions Metal cleanliness influences nearly all parameters of casted pieces and the casting process.Thus,tests of the melt material are of particular importance.With the devices of FMA the quality of the metal melts is simply investigated.
