Abstract

The invention relates to a new method for measuring aluminum liquid height in daily management of electrolytic cell in aluminum smelting industry. The invention comprises following procedures. 1) Measuring support is set on the furnace platform of aluminum outputting port of electrolytic cell. 2) The front end of measuring drill inserts into electrolyte to measure the boundary of electrolyte and aluminum liquid. 3) The distance x between the boundary and the line at the root of measuring drill. 4) Aluminum liquid height h-x is calculated. The invention is provided with following merits. 1) Measuring height and measuring tool are unified and measuring position is not restricted. 2) Because there is no need to contact with the furnace bottom by measuring drill measuring error generated by drill tip melting because of over large local current when the tip of measuring drill often contacts with the furnace bottom can be avoided. 3) It is available for improve the situation of furnace bottom of crusted electrolytic cell. 4) Error by hole of cathode at the aluminum outlet port can be avoided. The invention can be applied in measuring management for aluminum liquid height of all groove-type aluminum electrolytic cell.

Description

technical field

[0001] The invention relates to a new method for measuring the height of molten aluminum in the daily management of electrolytic cells in the aluminum smelting industry, in particular to a method for measuring the height of molten aluminum in an aluminum electrolytic cell. Background technique

[0002] On the electrolytic cell with carbon cathode, a certain amount of aluminum liquid (also known as aluminum in production) needs to be accumulated at the bottom of the furnace. , so that the temperature throughout the electrolytic cell is uniform; the third is to weaken the influence of electromagnetic force and stabilize the aluminum liquid. Therefore, its quantity must meet the heat balance design and magnetic field balance design of the electrolytic cell at the same time, and the production should be maintained according to the design quantity.

[0003] The height of molten aluminum is an important factor affecting the heat balance o...
