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 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 کاملHot Corrosion Behavior of Magnesite – Chromite Refractories Used in Reverberatory Furnaces at Sarcheshmeh Copper Complex
Iran’s Sarcheshmeh copper industries with an annual production of 120,000 tones are the biggest of it’s kind in South Asia. The main method of production is pyrometallurgical matte making in two reverberatory furnaces which use direct–bond magnesite-chromite refractories supplied by German and Austrian companies. Following a recent major overhaul, bricks in contact with slag, matte and furnace ...
متن کاملInteraction Mechanism between Refractory and Melts in Iron Bath Smelting Reduction Process
The corrosion behavior of three sorts of refractories based on alumina-graphite were studied by immersion tests. The melts included smelting reduction molten slag and corresponding carbon saturated molten iron. The influence of test temperature, FeO content in slag and specimen rotative velocity on the corrosion rate of refractories was examined. By means of SEM and EDS, the microstructure chan...
متن کاملThe Effect of Carbon Nanoparticles and Calcined Alumina on Mechanical Properties and Corrosion Resistance Behavior of the Magnesia Carbon Refractories
Nowadays, magnesia carbon refractories are very important for the iron and steel industries. It is due to their unique properties, such as low wet ability with melt iron and steel. Therefore, it is important to extend the life of the refractory. In this research, the effect of calcined alumina and nano carbon on mechanical strength and corrosion resistance against slag in magnesia carbon refrac...
