METHOD FOR OPERATING A MELT-METALLURGIC FURNACE, AND FURNACE

摘要

The method involves maintaining a number of operating parameters within preset thresholds. Correcting variables are fed to a mediator (11) from a control or regulating unit (9) and a fuzzy regulating unit (10) of a control or regulating device (1). An actuating signal utilized according to a preset weighting factor is calculated by the mediator from the correcting variables. Amount of gases applied in a heating unit of an electric arc furnace (2) is provided as the operating parameters.
