摘要

A functional diagram of a temperature controller of electric resistance furnaces with temperature difference compensation in thermal zones by means of automatic correction of power arriving to the thermal zone is given. The additional power required for compensation of the temperature difference in thermal zones of the furnace is determined. The power depends on the temperature difference between thermal zones during heating, heating temperature, and given permissible temperature difference between thermal zones. Dependences of the relative additional power upon the temperature difference between thermal zones at heating temperatures in a range of 700- 16OO°C and permissible temperature differences between thermal zones 5,15, 30, and 50°C are determined. Recommendations on the control system adjustment are given. The adaptive control system for thermal zones of electric resistance furnaces is developed.
