cement powder, slag dust, sinter emis sion, and graphitic coke. This approach has been successfully employed by Feldstein et al.,1in the differentiation of cement emission from asphaltic batching material, and has also yielded quantita tive results as shown by Leroux2in cases where glass fiber filters have been im pregnated with pure standards.
· The assay was proved to be highly sensitive with a detection limit of 10(2) CFU/ml without preenrichment, and highly concordant () when compared with ISOIDF 22964 in 89 actual samples. The method performed for Cronobacter spp. detection was less than 24 h, drastically shortened, compared to several days using standard culturing method, it is probe .

Abstract: When liquid steel is tapped from a basic oxygen furnace (BOF), it is essential to minimize the quantity of .
EMLISIL Ladle Slag Detection System. The EMLI III Ladle slag detection system uses stateoftheart electronics and custom designed sensors to detect the presence of slag in the well block area of the ladle. The proprietary sensor design and sensor placement allows the EMLI system to generate a reliable and accurate slag alarm far in advance ...
This paper deals with the production of mortars prepared using a commercial CEMIIBS cement, a natural aggregate, steelmaking slag, a superplasticizer and water. The asreceived unprocessed steel slag was milled by a hammer mill and then sieved
1 day ago · The powdered specimens of lithium slag and sodium tetraborate decahydrate were placed on carbon tapped stub followed by sputter coating of carbon which was subsequently tested for SEM/EDS on Tescan VEGA 3. The quantitative oxide composition of calcined lithium slag was determined to be spiked with 4% lithium nitrate as an internal standard.

Ladle furnace slag samples were prepared for EDS analysis as follows: 4 grams of each powdered sample (particle size less than mm in diameter) was pressed into pellets of 20 mm in diameter (15 tons pressure, 30 s dwelling time). No binder material was applied. The samples were placed in standard sample holders and
· (a) Detection of Cronobacter sakazakii in BPW with an initial concentration of 22 ± 2 CFU in 25 g of PIF. Average signals of three spots of the same antibody: C5 antibody, C9 antibody, SA2 antibody and Negative control antibody. (b) Detection of Salmonella Typhimurium in BPW with initial concentration of 18 ± 2 CFU in 25 g of PIF.
· A synthetic Ferich slag resembling industrial copper or lead slags, was mixed with a sodium silie activating solution. 57 Fe Möss spectra analyses indie that the oxidation reactions are taking place simultaneously with the polymerization reactions. The slag contains Fe 2+ states and a small amount of Fe 3+.
· Xray powder diffraction (XRD) is a rapid analytical technique primarily used for phase identifiion of a crystalline material and can provide information on unit cell dimensions. The analyzed material is finely ground, homogenized, and average bulk composition is determined. Fundamental Principles of Xray Powder Diffraction (XRD)
Ladle Slag Detector Gate Closure System. In the early 90's, TelePro was approached by a vendor who had an idea for a slag detection concept. It involved monitoring the vibration signature of steel flow to detect the presence of slag. The new concept of "listening" to the steel flow differed from other existing methods of slag detection ...
From about 5 g of a representative sample powdered slag, frac tion passing through 90 pm iS Sieve and retained on 52 pm IS Sieve shall be treated as the sample for microscopic investigation as under IS : 12089 1987 . Is: ( ) ( ( ( _ Bureau of Indian Standards ...

tensive research on slag chemistry–property relationship has been carried out in order to optimize slag composition for more effective secondary metallurgical reactions,1–8) to control inclusion type, size and distribution,9) and to improve molten steel ) Slag composition also determines the physical properties
The Tozato Slag Detector, for continuous monitoring of metal teeming ladles, is equipped with a very sturdy software that uses a shielded vibration sensor and a high quality optical sensor, giving the system an unique performance in monitoring the slag carryover from the teeming ladle to the tundish. The triaxial vibration sensor has precision ...
· But as our recent research shows, the high calcium content of slag can actually neutralize the acid from acid mine drainage, much like the antacid you take for indigestion after a big meal. Not only that, but it can even reduce acids that have built up in soils. We looked specifically at ferrous slag, the leftover material from the smelting of ...
1 day ago · The XRD of powdered lithium slag specimen was performed upon mixing 10% weight of fluorite as an internal standard, micronized in ethanol suspension for 10 min to get the homogenous mixture. The specimen was dried for 24 h on a hotplate (40 °C) and was filled in the specimen holder step by step with a glass slide to avoid the preferred orientation of crystals [ 25 ].
