Abstract: To solve the problem of heat balance(HB) supervision & control of point-feeding aluminium reduction cells, an adaptive predicting estimation model (APEM)of dynamically balanced bath temperature (DBBT) is established，which co-operates with a temperature measuring device，the later employing the method of temperature dynamic measurement (TDM) and operating in intermittent way. Since it can realize quantitative description of the relationship between the output-DBBT and the inputs-heating power and equivalent feeding rate，of a HB system，APEM can be used in the design of a HB supervision & control system of a point-feeding cell.Its effectiveness has been tested by using the data measured on a 160kA point-feeding prebaked anode aluminium reduction cell.
