The use of mathematical models of control processes in foundry such as: K-test and Chemical spectral analysis is a good set of mathematics (thermal conductivity theory) and theoretical physics (first-order phase transition) are important elements for ensuring high quality castings in micro-foundries.
The idea of estimating the overheating of a liquid metal alloy based on the appearance of a curing process upon filling has been developed. These control processes combined with zone refining are an important opportunity to create a waste-free foundry in a circular economy in Industry 4.0.
