THE EFFECT OF GRAPHITE ADDITION ON CORROSION BEHAVIOR OF TAR BONDED DOLOMITE REFRACTORIES IN STEELMAKING CONVERTER
Abstract: Dolomite based refractories are widely used in Iranian steelmaking plants. In the present research, wear and corrosion of refractories used in steel-making converter lining in Esfahan Steel Company was studied. Post-mortem analysis of refractories clarified that the wear started with oxidation of carbon followed by chemical corrosion. Iron oxide from slag reacted with calcia, resu...
متن کاملInfluence of Wettability and Reactivity on Refractory Degradation – Interactions of Molten Iron and Slags with Steelmaking Refractories at 1550°C
Refractories, materials that can withstand high temperatures, play an important role in the iron and steel sector which alone accounts for ~70% of total refractories pro‐ duced. In this chapter, detailed wettability and interfacial phenomena investiga‐ tions on alumina-carbon and zirconia-carbon refractories at steelmaking temperatures. The wettability between refractory substrates and molten i...
متن کاملInvestigations of Calcium Aluminate Slag Penetration to MgO Monolithic Refractories in Steelmaking Process
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 ...

متن کاملRECYCLING PRACTICES OF SPENT MgO-C REFRACTORIES
The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...
