dcterms:description
Development of hollow ingot casting technology began in VÍTKOVICE HEAVY MACHINERY a.s. based on the growing demands for production of large hollow forgings, i.e. in particular shells, or hollow rings and pulleys. The use of hollow ingot as a semi-finished product for the production of forgings mentioned above brings not only economic efficiency but also achieves better quality parameters in the finall forgings. Forging properties are more homogeneous in all directions and the scale of the macro-segregation is significantly lower than in case using conventional ingots. Forgings can then be used for the most demanding requirements, including applications for nuclear power because of their greater safety and durability. Numerical simulations of casting and solidification were used during the development of hollow ingot casting technology. The final variant of casting system, which has been verified in practice, was chosen just based on these simulations. This paper describes experience with the introduction of hollow ingot casting technology and evaluation of the first tests of hollow ingots.
