Building foundations for the diffusion mechanism of ceramic mould drying

An attempt was made to develop a mathematical model and apply this model in numerical analysis to the drying process of multi-layer ceramic moulds used in investment casting. The numerical analysis carried out in a FLOW-3D program was meant to ser...

Analysis of the drying process of moistened surface layers of sand moulds and cores on the example of moulding sand with water glass

An analysis of the drying process of surface layers of sand moulds and cores (made of loose self-hardening moulding sand with hydrated sodium silicate hardened with a liquid ester hardener) which was previously subjected to the process of moisture...
