Abstract:
The smelting temperature is an important factor in copper smelting process by oxygen bottom blowing which affects matte grade, smelting slag type, properties of melt and furnace body erosion. It is the key that keeps the smelting process running normally. The production data is collected to calculate heat balance of copper smelting. Utilizing Fluent numerical software and coupling an equivalent solid heat source, the distribution of temperature is studied in the copper smelting process. Meanwhile, the effects of technical parameters, such as gas flow rate, the temperature of oxygen-enriched air, and bath depth on the distribution of temperature are discussed. The results showed that there exist a high-temperature zone in the action area of oxygen lance and the flue outlet. As gas flow rate increases, the smelting temperature decreases. The reason for this is that the smelting flue quantity increases and takes away more heat at a certain heat release rate. The low-temperature zone of oxygen lance opening expands as the temperature of oxygen-enriched air decreases which is in favor of protection of oxygen lance. The smelting temperature decreases as bath depth decreases, and the temperature is gradient distributed. This study simulated the distribution of oxygen bottom blown furnace, and has a certain guidance to the practical production.
