Oxygen top-blow converter is the main equipment in steelmaking. Because the support system of converter bears total weight of the converter and its accessories, and meanwhile transfers tilting torque from tilting mechanism to converter, it is the most important part of converter machinery. The joint equipment which links the converter with the support ring is the key part in the support system,...

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...

The investigation of electric arc furnace (EAF) steel slag as a viable add-on technology to existing stormwater systems for the removal of dissolved phosphorus (P) was extended to explore the effects of varying environmental and treatment system conditions. Parameters such as stormwater composition, P concentration, metal concentration, pH, temperature, slag mass and slag particle size were var...

Silicomanganese (SiMn) is an alloy used in steelmaking to provide both Si and Mn additions at low carbon contents. In South Africa, SiMn is produced in three-phase alternating current (AC) submerged arc furnaces (SAFs) by carbothermic reduction of manganese ores in the form of lump, sinter, and briquettes (Steenkamp and Basson, 2013). In a SAF the electrode tips are submerged in a porous charge...

EPA has completed a substantial study to re-evaluate use of the presence of slag wool fibers as a potential marker for World Trade Center (WTC)-derived dust contamination. Slag wool is an insulating material (made from blast furnace slag) that was used in the construction of the WTC. Large quantities of slag wool were released into lower Manhattan by the collapse of the WTC. Samples of dust col...

Abstract. Obtaining an artificial stone based on steel-smelting slag is possible as a result of carbonization the feedstock in carbon dioxide. The - and dioxide are by-products from steel smelting electric furnaces, which must be disposed order to improve environmental situation region. condition for obtaining cementing ability steelmaking preparation charge with certain properties maturation t...

In this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. A synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°C and 1600°C. It has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°C. In this case, capillaries are the ...

This study presents the result of using melting to recover both industrial sludge slag (the main constituent of which is calcium fluoride) and water works sludge slag as fine aggregate in cement. The main characteristics of both slag and cement mortars were measured to evaluate the feasibility of using slag as aggregate. In this study, the slag replacement ratios were 0, 10, 20, 30, 40, and 50%...
