Procedimiento para el funcionamiento de un horno de arco

摘要

The method involves melting to-be-melted material in an arc furnace by a plasma arc produced by an electrode. The plasma arc is regulated by introducing additional substances influencing the plasma composition into the plasma. The state of the melting process is determined and the strength of the plasma arc is controlled in dependence of the melting process state. Independent claims are included for the following: (1) signal processing device for arc furnace; (2) arc furnace; and (3) machine-readable program code for signal processing stored in memory medium.
