compounds of stainless steel slags, calculated with thermodynamic data from HSC 8. It can be seen that from a thermodynamic point of view the reduction of chromium oxide is possible with manganese, silicon, aluminum and carbon at a temperature of more than 1200 °C. However, the Gibbs free energy difference of chromium oxide and manganese oxide are low and therefore it is not feasible to use ...

This means that the contraction of the steel is not calculated and taken into account,, the density cannot be varied either. In such cases, the density should be that of the initial liquid and constant. However, during solidifiion, the fluid in interdendritic space is free to move, and it more or less compensates the so lidifiion contractions. To take this feeding into ac count ...
