全热态连续炼铜中底吹炉氧枪的设计及应用OA

By exploring the coordination of side blowing furnace and bottom blowing furnace,the fully hot continuous copper smelting process was realized.As one of the core equipment of bottom blowing,the performance of oxygen lance has a very important impact on the quality of crude copper,stirring strength and operating cost.The technology of"single lance with single control",Nitrogen mixing in compressed air pipe and optimizing the number of holes in oxygen lance core were adopted in a domestic copper industry to strengthen the performance of oxygen lance.The production practice shows that the effect of intensified blowing is obvious.
