NOUFERROUS METALLURGICAL EQUIPMENT

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 300kt/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.
