Summary

Lectures: 1. Foundry mould-core, sand mixtures of the I. to IV. Generation 2. Gating of castings, calculation of gatings, 3. Upward pressure of mould and of cores, crystallization and solidification of castings. 4. Changes in volume of metal at solidification and elimination of the thermal nodal sites in casting 5. Heat transmission between casting and mould 6. Defects in castings, running property of liquid metal, condensing zone of water and its consequences on the surface defects 7. Defects due to stress (overflows, scabs), penetration of liquid metal into mould, surface roughness of castings. 8. Failed compactness of castings, the mechanism of initiation of fissures and cracks. Foundry stress 9. Fabrication of castings by application of elevated pressure at the liquid- metal surface 10. Specific methods of fabrication of castings, vacuum aspiration, method of pouring precise castings 11. Steels for castings. Carbon and alloyed steels. 12. Graphitizing alloys of iron, melting routes 13. Design of castings, principles of optimum design 14. Nodular cast iron, metallurgy,
