Fused Magnesia-Based Refractories with Improved Heat Resistance

Fused Magnesia-Based Refractories with Improved Heat Resistance The introduction of various additions into fused magnesia-based refractories is studied in order to make these products more heat-resistant and reduce the cost of producing high-performance refractories. The study results are used to attempt to improve the heat-resistance of refractories through the addition of Cr2O3 However, the formation of ferrochromium during the refining operation lowers the refractories’ service temperature. The optimum addition turns out to be 5 – 15% unfired magnesite MgCO3. Refractory products with improved heatresistance can be effectively used in the linings of high-temperature equipment employed in ferrous and nonferrousmetallurgy, including fluidized-bed furnaces, Kivtset-TsS furnaces, horizontal converters, ore-roastingfurnaces, vertical converters, and electric furnaces used in ferrous metallurgy. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

The introduction of various additions into fused magnesia-based refractories is studied in order to make these products more heat-resistant and reduce the cost of producing high-performance refractories. The study results are used to attempt to improve the heat-resistance of refractories through the addition of Cr2O3 However, the formation of ferrochromium during the refining operation lowers the refractories’ service temperature. The optimum addition turns out to be 5 – 15% unfired magnesite MgCO3. Refractory products with improved heatresistance can be effectively used in the linings of high-temperature equipment employed in ferrous and nonferrousmetallurgy, including fluidized-bed furnaces, Kivtset-TsS furnaces, horizontal converters, ore-roastingfurnaces, vertical converters, and electric furnaces used in ferrous metallurgy.
