Recently, with the successful completion of the accuracy calibration of the tank pressure acquisition module of the last aluminum electrolysis cell control machine, it marked the completion of the annual calibration of the accuracy of the 300 500kA aluminum electrolysis cell pressure acquisition modules of the electrolytic aluminum plant of Guangxi Hualei New Materials Co., Ltd. .
Calibrating the accuracy of the cell pressure acquisition module of the aluminum electrolytic cell is an important task of the electrolytic aluminum plant, which is helpful for the process technicians to fully grasp the operating status of the aluminum electrolytic cell, improve the stability of the aluminum electrolytic cell and process technical indicators, and achieve the precision of the aluminum electrolytic cell. Lay a good foundation for management.
In order to reduce the negative impact that the calibration process may have on the control of the aluminum electrolytic cell, the equipment management business of the electrolytic aluminum plant organized a technical seminar for the user of the cell control machine and the maintenance party to jointly confirm the accuracy level of the cell pressure acquisition module, and formulated a thorough The calibration work plan.Subsequently, according to the requirements of the plan, the surveying personnel measured the tank pressure of 300 tank controllers one by one, and focused on rechecking and processing aluminum electrolytic cells whose tank pressure deviations were greater than the standard requirements, ensuring that the accuracy of the tank pressure acquisition modules of the entire series of tank controllers was uniform. Meet the process control requirements.
