An innovative approach is reported for recovering Fe and Zn resources from hazardous zinc-bearing electric arc furnace dusts (ZBDs) in a sustainable manner. A combination of carbothermal H2 reduction were used to overcome challenges associated with the high temperatures costs/limited supplies hydrogen. In-depth studies carried out using zinc-rich (17 wt.%), iron-poor (35 wt.%) ZBD; coke oven battery dry quenching dust (CDQD) was as reductant. Briquettes prepared by mixing ZBD CDQD powders...
Pyroxene glass-ceramic enamels based on combinations of blast furnace slag and some additives were produced investigated. The batch compositions technological regimes enameling developed to produce high temperature protective coatings for carbon steel (ASTM 1010/1008). composition raw materials was selected match the values thermal expansion coefficients coating (~11∙10−6 K−1) metal substrate (~12∙10−6 taking into account temperatures fluidization (Tf ~ 800°) crystallization (Tc = 850−1020...
Blast furnace slag is a key large-tonnage waste product of metallurgical production, which considered to be promising alternative material in construction. In order determine the scope potential use as marketable product, it necessary study its structure and composition, determined by means modern analytical instrumental methods. This paper analyzes application Fourier transform infrared spectroscopy (FTIR) chemometrics methods develop calibration models for identifying pelletized elemental...
Abstract The article presents the laboratory and industrial research analysis of impact modification refractory concretes products with finely-dispersed nanomaterials. dependence structural physical-mechanical characteristics mullite-corundum refractories different types (for ladle furnace lances for supporting blocks rolling mill carriages) on nanomodification by electromagnetic homogenization is shown. possibility using a vortex homogenizer to significantly improve performance In addition,...
This work studied biocomposites based on a blend of low-density polyethylene (LDPE) and the ethylene–vinyl acetate copolymer (EVA), filled with 30 wt.% cellulosic components (microcrystalline cellulose or wood flour). The LDPE/EVA ratio varied from 0 to 100%. It was shown that addition EVA LDPE increased elasticity biocomposites. elongation at break for 9% 317% microcrystalline 120% flour (with an increase in content matrix 50%). biodegradability assessed both laboratory conditions open...
A study of a two-stage method for the formation nanostructured Ni 3 Fe is presented. Nanostructured hollow microspheres were synthesized by ultrasonic spray pyrolysis (URP) from mixture aqueous 10 wt. % solution nickel (II) and iron (III) nitrates. At first stage, formed oxides with diameter in range 0,5‒10 microns. The second stage metallization tubular furnace hydrogen atmosphere. XRD data final product showed presence Ni3Al phase crystallite size close to 40 nm. Scanning transmission...
Glass-ceramic composites based on blast furnace slag have unique mechanical properties and can be used as wear-resistant lining of mining chemical equipment, electrical insulators, technical decorative materials in a number other areas. In this work, samples synthetic stone casting with various additives, including sand, glass cutting reagents, increasing the degree crystallinity melting products, were made. Studies obtained products shown that highest are characterized by material basis...
The influence of the method introducing silicon oxide (aerosil) into Portland cement on characteristics model concretes has been studied. Two main methods aerosil through a suspension obtained using an ultrasonic homogenizer and charge treatment in vortex layer apparatus (VLA) are considered. resulting were studied for phase composition, microstructure, compressive strength. injection activity was evaluated. effect VLA processing granulometric composition morphology particles
Hollow nanostructured copper molybdate microspheres CuMoO 4 were synthesized by spray pyrolysis. Synthesis was carried out in a tubular furnace the range of 700‒1000 ˚C with step 100 and subsequent heat treatment at 500 for 1 hour air. The effect synthesis temperature during pyrolysis on physicochemical characteristics samples hollow studied. obtained studied dynamic light scattering, thermogravimetric analysis (TG), scanning electron microscopy (SEM) X-ray spectral (XRS).
The effect of the synthesis temperature hollow microspheres cadmium ferrite in spray pyrolysis process was studied.
