摘　　要：某铜业公司是世界上首家采用侧吹+顶吹铜冶炼工艺单套产能在300 kt/a的铜冶炼企业,该企业使这种铜冶炼工艺达到了一个突破性的产能高度。侧吹炉生产总体上正常,但是顶吹炉在前期筑炉过程中出现了很大的缝隙,在后期生产过程中又出现了炉底检测温度过高、炉底工作层耐火砖漂浮的重大问题,本文对这些问题进行了深入的剖析,指出了顶吹炉在筑炉过程中出现很大缝隙的成因以及顶吹炉炉体结构、膨胀缝设置不合理导致炉底问题出现的根本原因,并对这些问题提出了针对性的解决方案。A copper company is the first copper smelting enterprise in the world to adopt side-blowing+top-blowing copper smelting process with a single production capacity of 300 kt/a,which makes this copper smelting process reach a breakthrough production capacity height.The production of the side blowing furnace is generally normal,but the top blowing furnace has a big gap in the earlier construction process,in the later stage of production,there are some important problems such as too high temperature of furnace bottom and floating of refractory brick in working layer of furnace bottom,this paper points out the cause of the big gap in the process of building the top blowing furnace and the basic reason of the bottom problem caused by the unreasonable structure of the top blowing furnace body and the setting of the expansion gap,and put forward the solution to these problems.
