This article analyses the electric energy loss of adjusting the line current by stages, which has a bigger wave motion when the anode effect happens-a phenomenon peculiar to aiu-minium reduction.

Using the airflow heating method to measure the calorific value on-line, and adding air to the gas to adjust the calorific value, a calorific value feedback adjusting system was developed.

The designers acknowledge that this is a problem and they plan on adjusting the higher-level damage to be more in line with the original concept.
