Abstract:Double bottom blowing continuous copper smelting process has the characteristics of continuity and instant, and its production operation parameter control is more complex than other copper smelting processes. In order to ensure the stability of product quality and optimization of furnace condition, it is necessary to study the key control parameters and their influence law of double bottom blowing continuous copper smelting process. In this paper, using the MetCal Desk computing platform, a metallurgical calculation model of double bottom blowing continuous copper smelting process was established based on the principle of conservation of material flow and energy flow. On this basis, through a single adjustment of oxygen rich air volume, quartz stone volume, electrolysis remnant pole volume and other parameters, the influence on the key smelting parameters "matte grade, iron-silicon ratio and temperature of smelting slag converting parameters "coarse copper grade, iron-silicon ratio and temperature of converting slag bottom blowing continuous copper smelting process were investigated. The research results showed that the grade of matte was positively correlated with the amount of smelting quartz and oxygenized air, but negatively correlated with the amount of coal. The iron-silicon ratio of smelting slag was negatively correlated with the amount of quartz and coal. The smelting slag temperature was positively correlated with the amount of oxygenized air and coal. The crude copper grade was positively correlated with the amount of oxygen-rich air and electrolysis remnant pole. The iron-silicon ratio of converting slag was positively correlated with the electrolysis remnant pole and negatively correlated with the amount of converting quartz. The converting slag temperature was positively correlated with the amount of oxygenized air and electrolysis remnant pole.
