1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

OBJECTIVES Little has been known about the risk of cancer associated with occupational exposure to manganese. The objective of this study was therefore to examine the associations between duration of specific work and cancer incidence among employees in four Norwegian ferromanganese and silicomanganese producing plants. METHODS Among men first employed in 1933-91 and with at least 6 months in...

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...

The increase in pollutant emissions has generated the development of clean technologies and encouraged use alternative fuels like syngas. Flameless combustion is one most promising due to lower pollutants high thermal efficiency. In present study, regenerative furnace simulation under flameless was carried out using a fuel mixture 70% natural gas 30% syngas with H2 content (in vol.); by mean CF...
