Performance Evaluation of Magnesia – Chromite Refractory in the Flash Smelting Furnace of a Copper Smelting Industrial Area

Abstract:

The demand for refractory materials continues to increase, particularly in the copper smelting industry. Flash Smelting Funaces (FSF) require refractories that can withstand high temperatures and aggressive chemical interactions. This study evaluates the performance of Magnesia – Chromite as refractory materials in FSF through tests such as Thermal Expansion, Porosity, Cold Crushing Strength, Bulk Density and Thermal Conductivity. Initial test results show that the brick has high resistance to thermal shock, with a thermal expansion value of -0.3% cold crushing strength of 63.4 Mpa, bulk density of 3.22 g/cm3, porosity of 12.76% and thermal conductivity ranging from 2.8 to 2.9 W/m.K.
