Far-infrared observations of young clusters embedded in the R Coronae Austrinae and RHO Ophiuchi dark clouds [PDF]

Multicolor far infrared maps in two nearby dark clouds, R Coronae Austrinae and rho Ophiuchi, were made in order to investigate the individual contribution of low mass stars to the energetics and dynamics of the surrounding gas and dust.

Population of Nonmetallic Inclusions in Liquid High‐Silicon Electrical Steel in Contact With MgO–C Refractories Based on Recyclates and Environmentally Friendly Binders

Advanced Engineering Materials, EarlyView.
The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...

Quantitative evaluation of the sealing effect of penetrating gas drilling and in situ repairing technology for smooth holes

Energy Science & Engineering
In this study, a new method is proposed to quantitatively determine the extraction of boreholes under the effect of time. The main purpose of this method is to divide the gas drilling holes in the monitoring time into two stages: the early stage of ...

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

Advanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...
