    摘要: In a method for regulating the melting process in an electric-arc furnace (1) which contains a furnace charge (4) containing the following temporally successive principal phases: melt, slag, solid, the proportion and temperature of at least the melt phase are calculated by a model (3). The model (3) embodied as a multispatial model for the different phases of the furnace charge (4), enables to include the physical effect according to which the temperature (TM) of the overheated melt decreases shortly before the complete dissolution of the remainder of the solid, in spite of the energy supply. Moreover, this effect is counteracted in that the electrical and/or chemical energy input is temporarily increased in a targeted manner. The modelling enables the real temperature profile (TM) of the melt to be represented, thus also improving the predictability of the tapping temperature. The number of temperature measurements required is, thus, reduced.

    摘要: The invention relates to a method for predicting and controlling the castability of liquid steel. According to said method, the chemical composition of a melt to be cast is analysed, an alloy calculation is carried out, alloy elements and/or additions are determined in order to obtain defined material characteristics of the steel, and operating diagrams are drawn up for further treatment of the melt. The interactions of the alloy and/or addition elements, which influence the castability, are taken into account during the alloy calculation as supplemental conditions.
