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...

The work contains the results of analysis technical literature and author’s research on use aluminium slags products their processing in metallurgical production. It has been shown that bulk reagents derived from secondary aluminum production wastes (APWs) are used with increased sodium potassium chloride. This creates some inconvenience for out‑of‑furnace steel treatment due to chloride conten...

Thegoal. Silicon carbide is one of the most essential artificial inorganic materials widely used to produce abrasive instruments, high-temperature heaters, fireclay ceramics, and metallurgy. The amount silicon produces in resistance furnaces. One issues production process lack supervisory thermal state furnace working space, which does not always allow for select rational electrical modes accor...

In graphite furnace atomic absorption spectrometry (GF-AAS), the atomization process of lead occurring in graphite atomizers with/without a platform plate was investigated when palladium was added to an iron-matrix sample solution containing trace amounts of lead. Absorption profiles of a lead line were measured at various compositions of iron and palladium. Variations in the gas temperature we...

This article presents the results of a research on recycling wastes from metallurgical plants in city Pavlodar at steel smelting plant KSP Steel. The pellets were produced with aspiration dust and mixed steelmaking (white) slag, ferrous sand, scale. fired temperature 600 ° C. experience use 20% white sand 10% mill scale shows, after burning furnace, quite satisfactory strength, which is 80 kg /...

Abstract In this work, fire simulations were carried out on zinc-coated steel sheets usually employed for the structural parts of furniture, transformer rooms and aeration pipes. The thermal alteration induced by was simulated heating samples at 13 different temperatures (from 20° C to 1050° C) exposure times (1 h 6 h) in a laboratory furnace. metallurgical investigation concerned surface color...

The iron and steel making is considered among the biggest industries which run world. This industry contributes around 20% of global industrial-sector energy consumption that provided significantly by coal coke. fossil-based fuels are consumed largely for heat generation reducing agents in production processes leads to huge CO2 emissions. matter encourages find an effective, environmentally fri...

Metallurgical dusts are by-products from steel manufacturing. The high iron content of cast house dust (~64%) makes this by-product an interesting feedstock alternative. Therefore, its return into the internal steelmaking circuit, specifically in sinter plant, is a common practice industry. However, fraction also contains heavy metals, as zinc. As result re-entry zinc process, concentration bla...

In reactor furnace, due to high temperature and high pressure, data can be measured only near the furnace wall. In this paper, the way to estimate temperature distribution in a reactor furnace using measured data near the furnace walls and to control temperature distribution to the desired temperature distribution was studied. In the estimation, SQP method is employed using measured data near t...

Abstract The article presents innovative technology which integrates a metallurgical pusher-type furnace with waste heat recovery system that consisted of reactor for torrefaction and pyrolysis biomass. is designed utilizing both liquefied gaseous by-products (torgas, gas condensate denoted as TPC) obtained from TPC considered to be applied an additional fuel example effective energy management...
