Embodiment 1
[0042] Embodiment 1: a kind of aluminum electrolyzer utilizes flame roasting to start the process directly, and it comprises the following steps successively,
[0043] (1) Select the 5046# electrolytic cell of the 240KA electrolytic series;
[0044] (2) Install the anode used in the electrolytic cell, connect the detection and control system, and confirm that the equipment is installed in good condition;
[0045] (3) Install the gas control system and determine the position of the gas burner: Before the electrolytic cell is roasted, install the gas control system in the electrolytic plant according to the site conditions; divide the electrolytic cell into four roasting areas, and place a burner in each roasting area Temperature Sensor. There are 3-4 gas burners in each roasting area, and the gas burners are reasonably and evenly installed between the bottom of the anode and the upper part of the cathode in the furnace of the electrolytic cell; preferably, the gas burners are ...
