| Abstract: |
| Direct reduction process with bottom blowing furnace of molten rich-lead slag from oxidation smelting of lead concentrate was described. Characteristics and innovation of lead direct smelting technology are analyzed. Based on transformation rule of main elements and components during smelting process, material and thermal energy balance of rich lead molten slag in direct reduction process were analyzed. Thermal balance models of molten rich lead slag di-rect reduction were established by Gauss Elimination Method. Thermal field distribution in bottom blowing direct re-duction furnace and heat utilization was studied. Characteristics of smoke area on top of furnace, wave area of slag and pool area at bottom of furnace in molten rich lead slag direct reduction were discussed. |
