Analysis Of Mubi Clay Deposit As A Furnace Lining

Mubi clay was investigated to examine if the deposit can be used as a furnace lining material. The result shows that the clay has a bulk density of 2.3g/cm 3 , apparent porosity of 13.70%, firing shrinkage of 9.6%, thermal shock resistance of 8 cycles, cold crushing strength of 253 kg/cm 2 , loss on ignition of 4% and refractoriness of 1,300 0 C. The percentage composition of impurities is generally below 2.0% while iron II oxide account for 5.986%. The chemical analysis shows that the percentage composition of Aluminium oxide (Al2O3) is 18.1% while the Silica (SiO2) content is 67.7%. The results obtained from Mubi clay showed that the clay can be used for lining of heat treatment furnace , melting furnaces for low melting point metals, liquid metal ladles and por tions of blast furnaces.
