Abstract
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 analyzed, 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.
