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 کاملTHE EFFECT OF NANO METER SIZE ZRO2 PARTICLES ADDITION ON THE DENSIFICATION AND HYDRATION RESISTANCE OF MAGNESITE– DOLOMITE REFRACTORIES
In this study the effect of nano meter size ZrO2 particles on the microstructure, densification and hydration resistance of magnesite –dolomite refractories was investigated. 0, 2, 4, 6 and 8 wt. % ZrO2 particles that were added to magnesite –dolomite refractories containing 35 wt. % CaO. The Hydration resistance was measured by change in the weight of specimens after 72 h at 25℃ an...

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...
متن کاملAn investigation on thermal behavior of Shahreza dolomite ORE
Thermal behavior of the Shahreza dolomite ore is investigated in this paper. The hydration of the calcined dolomite was studied as a function of the calcination temperature. The DTA results exhibit three endothermic peaks at 800, 900 and 1050 °C, corresponding to decomposition of MgCO3 and CaCO3, both are present in dolomite and free calcite, respectively. The results also indicated that the de...
