Simulation Of Oxidized Lead Melt Infiltration Through The Carbon Material Layer

Id Paper: 124
Topic: 6
Abstract:
A compact porous layer of lump carbon material is used as the main reduction reactor in flash smelting processes for lead raw materials. Such layer, which was named as “coke checker”, forms at the surface of slag melt bath directly under the flare of the charge burner. Reduction of highly-dispersed oxidized lead melt, which is produced during charge flash smelting, is performed during the infiltration of the melt through the carbon reductant layer. The Paper provides the results of studies of the specified process by means of the mathematic model of the coke checker with due consideration of phenomena of heat and mass exchange in the layer, its geometry and continuity of the melt flow. The results of model calculations are compared with the established industrial practices.
