The loss of permeability affects the reduction ferrous burden in cohesive zone a blast furnace (BF). Vanadia–titania magnetite (VTM) various chemical compositions have different metallurgical properties. and softening-melting-dripping properties kinds VTM were investigated. results showed that core sinter or pellet is indirectly reduced to wustite (Fe,Ti)Ox, periphery contains interlinked metal...

In the vitrification of nuclear wastes, the melter feed (a mixture of nuclear waste and glass-forming and modifying additives) experiences multiple gas-evolving reactions in an electrical glass-melting furnace. We employed the thermogravimetry-gas chromatography–mass spectrometry (TGA-GC–MS) combination to perform evolved gas analysis (EGA). Along with identifying the gases evolved, we performe...

Selecting a set of representative prototypes in prediction systems enable us to generate prototype based rules (P-Rules), which constitute a very powerful means of providing domain experts with knowledge about the data and the process depicted by the data. P-rules has already proved very useful in classification tasks. This paper investigates application of P-rules to regression problems. The p...

Powder samples and single crystals of the boride phases MxRh7−xB3 (M = Cr, Mn, Ni; x≤ 1) have been synthesized from the elements using an arc-melting furnace under purified argon atmosphere in a water-cooled copper crucible. The new phases were characterized from single-crystal and powder X-ray diffraction, as well as semi-quantitative EDX measurements. The obtained phases crystallize in the he...

This paper describes an application of a CBR System in a factory, which manufactures Fused Cast (Electro Cast) Refractory blocks used as Lining for Glass Melting Furnace Tanks. The attributes, which are associated with the manufacturing process, are captured in the shop floor. The CBR system enables the users and the experts to correlate the dependence of the success and failure of these blocks...

A well crystallized sample of U 2A13C4 was obtained by melting the elemental components in a carbon crucible in a high frequency furnace. The crystal structure of this compound was determined from single-crystal diffractometer data of a twinned crystal: P 63mc, a = 342.2(1) pm. c 2323.0(3) pm. Z 2 , R 0.030 for 537 structure factors and 18 variable parameters. The structure can also be describe...

The metal-rich intermetallic compounds NblrSi, NblrGe, and TalrSi were synthesized by arc-melting of the elements and subsequent annealing in glassy carbon crucibles in a high-frequency furnace. The three compounds were investigated by X-ray diffraction on powders and single crystals: TiNiSi type, Pnma, a = 641.27(3), b = 379.48(2), c = 727.70(3) pm, wR2 = 0.0773, 430 F 2 values for NblrSi, a =...

Experiments were carried out to grow 3.Nitroaniline (m.NA) crystals doped with 4.Nitroaniline (p.NA) and 2.chloro 4.Nitroaniline (CNA). The measured undercooling for m.NA, p.NA, and CNA were 0.21 tm K, 0.23 tm K and 0.35 tm K respectively, where tm represents the melting temperature of the pure component. Because of the crystals' large heat of fusion and large undercooling, it was not possible ...
