Melting temperatures of iron-ore sinter

Prediction of the melting temperatures of pure metals, their oxides, and complex iron-ore sinter is considered. A simple formula for the energy state of solids is obtained. Other microstructural factors may be represented in the additive form of the Hall–Petch law. Alternative factors characterizing the energy state of iron-ore sinter are established. Formulas are derived for predicting the temperatures at which melting begins and ends in such sinter.
