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...

CHARACTERIZATION AND CORROSION OF BCC-TANTALUM COATING DEPOSITED ON ALUMINUM AND STEEL SUBSTRATE BY DC MAGNETRON SPUTTERING by Chirag Joshi Tantalum is one of the most versatile highly refractory corrosion-resistant metals. Tantalum coating can be used as an effective corrosion barrier if it is continuous, free from defects and it adheres well to the substrate. A DC magnetron sputtering techniq...

Abstract A thermodynamic model, based on SimuSage, was developed to simulate refractory corrosion between a magnesia-based material and ferronickel (FeNi) slags. The model considers theoretical cross-section of smelter application. current is structured into 10 zones, which characterize different sectors in the brick (hot cold side) perpendicular surface with an underlying temperature gradient....

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 ...

The use of sintered CaO as a refractory material is not uncommon. Refractory material based on lime as the lining of the Bessemer converter was applied for the first time in 1875 in order to carry out desulphuring and dephosphoring of the molten pig iron. Due to interaction of the porous burned CaO with the atmospheric moisture during dead time followed by damage and disintegration of this case...

gasification (BBLG). One particularly harsh application is linings for gasifiers used in the treatment of black liquor (BL). Black liquor is a water solution of the non-cellulose portion of the wood (mainly lignin) and the spent pulping chemicals (Na2CO3, K2CO3, and Na2S). Development of new refractory materials for the black liquor gasification (BLG) application is a critical issue for imp...
