After the technological upgrading,one smelter has become the first 240 kA potline in China to use graphitized cathodes.At the initial stage of operation,due to the fact that the production experience of graphitized cathode aluminum reduction pots was lacking,so the aluminum reduction pot was cold and the process technical indicators did not reach the expected value.The process technical team of the smelter conducted experimental research on the potline current,pot voltage,metal level,molecular ratio and other process conditions,and finally formed the process control standard of"Four-low and One-high".Through the implementation of this standard and refined production management,the efficient and stable operation of aluminum reduc-tion pots was achieved.
