Defects and properties of heavy castings

By Petr Sobotka


A diploma thesis was objected to a figure analyzing and a figure interpretation of ingot processing. The described figures were obtained from samples which were taking from feeder-heads of ingot of lower ram, produced in Vitkovice Machinery Group. The thesis was focused on ingot solidification and segregation processes which were associated with this procedure. The figures obtained from numeric simulation of ingot solidification in defined places were analyzed using statistic method – linear regression, as well as linear regression was used for evaluation of explored samples, their chemical compositions and mechanical properties. In conclusion all acquired results were summarized

Topics: odmíšení.; solid ingot; numerická simulace; segregace; Nálitek; exsolution.; Feeder; celkový teplotní gradient; masivní odlitek; numeric simulation; segregation; temperature gradient
