Abstract

An on-line real-time aluminium electrolyzing parameters measuring process includes the steps of detecting the primary crystal temperature by inserting the measurer probe into electrolyzer and sendingout the primary crystal temperature signal; and processing the signal and calculating other electrolysis parameters according to the set mathematical model. The probe of the present invention includes thermocouple, metal ball and protecting tube, and the thermocouple inside the protection tube has its end inserted to the geometric center of the metal ball. The present invention can measure and find out important aluminium electrolyzing parameters timely and precisely, and this makes it possible to realize the autocontrol of aluminium electrolyzer for raising its current efficiency, reducing the power consumption and raising the yield.

Description

technical field

[0001] The invention relates to a temperature measurement method and an instrument used for the measurement in a high temperature and strong corrosion environment, in particular to an online real-time measurement method and a measuring instrument for aluminum electrolysis parameters. Background technique

[0002] In the current electrolysis, the verification and measurement of various parameters such as the concentration of alumina, the temperature of the initial crystal of the electrolyte, etc., is based on on-site sampling, and it takes about 1-2 days to perform laboratory analysis in the laboratory using traditional methods. If the time is too long, the electrolytic cell cannot be effectively controlled in time, and the sampling process brings great errors due to human factors, which is meaningless for guiding production. And other useful parameters (electrolyte convective heat transfer coefficient, electrolyte integrated flow rate and variation of alumina...
