desulfurization of plain carbon steel by cao-al2o3-sio2 and cao-al2o3-sio2-x (x = na2o, sro) synthetic slags
synthetic slag process decreases sulfur and phosphorus contents of steel, improves inclusion removal, protects steel from atmosphere and prevents temperature drop of the liquid steel in the ladle. in this study, the synthetic slags of ternary cao-al2o3-sio2,and quaternary cao-al2o3-sio2-na2o and cao-al2o3-sio2-sro systems were pre-melted and then were kept in contact with the liquid steel in a ...
متن کاملEFFECT OF A FOURTH COMPONENT (Na2O, SrO, MgO AND BaO) ADDITION TO CaO-Al2O3-SiO2 SYNTHETIC SLAG ON SULFUR REMOVAL FROM PLAIN CARBON STEEL
In this paper, the effect of MgO, BaO, Na 2 O and SrO addition to a pre-melted CaO-Al2O3 -Si 2 O synthetic slag on sulfur removal from plain carbon steel was studied under the same experimental conditions. The slags were pre-melted at 1400°C in an electric resistant furnace and desulfurization experiments were carried out in a high frequency induction furnace. The results showed that ...
متن کاملInteraction between Deformation and Crack Initiation under Vickers Indentation in Na2O–TiO2–SiO2 Glasses
An observed minimum in the critical crack initiation load at Poisson’s ratio (ν) of 0.21–0.22 in Na2O–TiO2–SiO2 glasses was investigated. Vickers indentation was used to examine hardness and average cracking length, fracture toughness was measured through the single-edge pre-cracked beam method, and volumes of densification and shear flow around indents were measured using atomic force microsco...

متن کاملMagnetic properties of praseodymium ions in Na2O–Pr2O3–SiO2 glasses
Sodium praseodymium silicate glasses of nominal composition 0.3Na2O xPr2O3 (0.7 x)SiO2, where 0pxp0:10; have been studied by magnetisation and X-ray photoelectron spectroscopy (XPS). The magnetisation data fail to collapse to a single curve in the M versus H=T representation for all values of x and the spread increases with x; indicating an increase in the magnetic exchange interaction. The M v...
