Abstract

Abstract The effect of waste linear low density propylene LLDPE addition on the reduction of FeO-containing slag by metallurgical coke has been investigated through experiments conducted in a laboratory scale horizontal tube furnace. Composite pellets of EAF slag 47.1 FeO with coke LLDPE and blends of cokeLLDPE in four different proportions were rapidly heated at 1520 C under high purity argon gas and the off gas was continuously analysed for CO and CO2 using an online infrared gas analyser IR. The extent of reduction after ten minutes level of carburisation and desulphurization were determined for each carbonaceous reductant. The results show significant improvements in extent of reduction along with improved levels of carburisation and desulphurisation of the reduced metal when coke was blended with LLDPE.
