Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

this study aimed at evaluating some quantitative and qualitative properties of potato as one of the main commercial products in iran. to this end, a split plot experiment on the basis of randomized complete bloke design with silicone and iron was carried out in jiroft as one of the commercial area of planting potatoes. the main factor included different levels of silicon (0, 10, 20, 30 mm.l-1) ...

This paper evaluates the treatment of textile dyeing wastewater by using steel scrap as adsorbents and heterogeneous catalysts for Modified Fenton oxidation. The efficiency of the process was explored as a function of the experimental parameters: pH, hydrogen peroxide concentration and Steel scrap content. The composites with high steel scrap content were effective to adsorb colour and COD in t...

We investigated the suitability and applicability of Pseudevernia furfuracea (L.) Zopf for environmental genotoxicity assessment. P. furfuracea lichen specimens were collected from 10 different Pinus species, in every 5 km, starting from around an iron-steel factory located in the central area of Karabük Province up to Yenice Forest. The impact of the pollution sources such as iron-steel f...

C. Roman, “Stefan cel Mare” University, Faculty of Economics, Suceava, Romania. Iron and steel industry is an important sector of the real Romanian economy, knowing the fact that, generally, the metallurgy is a very important indicator of internal consumption. The most important companies in this sector are part of international groups (Arcelor Mittal, Mechel, TMK and Tenaris), which ensure an ...

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 /...

Amorphous silica and alumina of metakaolin are used to adjust the bulk composition of black (BSS) and white (WSS) steel slag to prepare alkali-activated (AAS) mortars consolidated at room temperature. The mix-design also includes also the addition of semi-crystalline matrix of river sand to the metakaolin/steel powders. The results showed that high strength of the steel slag/metakaolin mortars ...
