Abstract

The computerized remote monitoring method on temperature in aluminum electrobath casing is implemented by means of a temperature measuring device, a user side computer connected between the temperature measuring device and the network, a monitoring side computer connected to the network, a web server and a data storage server. The monitoring process includes the following steps: measuring the temperature in the preset points of the electrobath with the temperature measuring device; saving the temperature data in the database of the data storage server with the user side computer; accessing the database with the monitoring side computer via Internet and the web server; judging whether to have measured temperature higher than the critical temperature and storing the related data in the temporary list if yes, and further judging whether to finish the data search; and returning the data from the temporary list to the monitoring side computer for display and alarming.

Description

technical field [0001] The invention relates to a method for monitoring the shell temperature of an aluminum electrolytic cell. Background technique [0002] In the production process of metal primary aluminum, the electrolytic cell is a production equipment for electrolysis and reduction of alumina to pure metal aluminum. Its operation status is directly related to various production indicators of the metal such as output, current efficiency and energy consumption. Electrolysis is carried out in a high-temperature molten cryolite electrolyte at 930-970°C. If the temperature is too high, the "secondary reaction" of the reduced metal will be strengthened, and the current efficiency will be reduced; the side of the electrolytic cell will melt, and the electrolyte will directly corrode the refractory material, resulting in the corrosion of the electrolyte and / or aluminum water on the steel plate of the cell shell, resulting in early damage to the electrolytic cell , causing se...
