what is the apparent porosity for chromite

The overall rates of carbon decrease in the alloy were reported but these data were not translated into apparent interfacial reaction rates. 2.5 Reduction of chromium in solution in slag by carbon in molten alloy Yokoyama et al. [89] reported a series of experiments examining the reduction of chromite ore with Fe-Si-C melts in graphite crucibles at temperatures between 1743-1903K. Rotary dryer for chromium and chromite what is the apparent porosity for chromite. rotary dryer for chromium and chromite chromite ore crusher machine and chrome ore beneficiation plant chrome is the value ore because of high corrosion . get price sodium

Study of Liquid Phase Formation during the Sintering of

the chromite particles resulting in pellets with low porosity and high compressive strength. Figure 5 also confirm the effect of silica on strength of pellets. Reactivity of very high strength pellets in smelting process is lower due to poor porosity and also formation of

EXPORTS AND RE-EXPORTS OF CHROMITE Exports and re-exports of ore have been primarily for the production of chromite based in Canadian or South American plants owned by U.S. firms. ' There is little processing of this ore except per- (2) haps some finer crushing.

63 E. Prestes et al. / Cermica 55 (2009) 61-66of the solid solution MgO-FeO area can be noticed. With high oxidizing conditions, the liquidus temperatures strongly rise for high values of iron oxide [4]. Table II shows chemical and physical properties of different

Free Opening Performance of Steel Ladle as a Function

For both studied materials (A1 and B1) an increase in the particle size (A2 and B2) enhanced the apparent porosity after firing, what resulted in a higher free opening. The increased on porosity suggests the formation of a weaker sintered layer due to the increase of critical flaw size.

100 (apparent specific gravity) Total Porosity 100 x = − [2] Apparent Porosity % W Wi −W = [3] where W = weight of dry coke, Wi = weight of wet coke. The results are presented in Table V. Table V: Specific gravities, bulk densities and

Apparent porosity is the ratio of the mass bone tissue in a specimen to the bulk volume of the specimen. Typical apparent densities for cortical bone and trabecular bone are 1.85 and 0.30 g/cm 3, respectively with a much higher variability and standard deviation for trabecular bone.

Instead, dunites may represent high porosity conduits formed by reactive porous flow. Using the observed size/frequency relationship, the assumption that dunites form a coalescing network and the requirement that flux is conserved where dunites merge, we estimate the total flux through a porous dunite network and the fraction of that flux that remains chemically isolated.

We developed and introduced a sonic method for determining the apparent density, porosity, and compressive strength of magnesite-chromite, chromemagnesite, and chamotte (fireclay) refractories. A method is discussed for mass control of steel-casting plugs

In some areas chromite reaches almost modal abundance, whereas in other parts chromite is so disseminated that it can hardly be recognized as a distinct layer. Such characteristics have also been reported for UG2 leaders in other localities in the Eastern Bushveld ( Mathez Mey, 2005 ).
