Electroslag Furnace as a Control Plant.

The results of studies of the transfer functions of individual components of an electroslag furnace as a control plant are described. In this case the slag bath is regarded as a receiver and a converter of electric energy into thermal energy, while the liquid metal bath is regarded as the ingot structure shaper. The effect of the furnace parameters on the values of the transfer coefficients and the time constants is considered. A structural diagram of an electroslag furnace as a control plant is presented which makes it possible to obtain the transfer function of the furnace for various control algorithms.
