Defects in steel castings
Jakubec, Petr ; Kaňa, Václav (referee) ; Pernica, Vítězslav (advisor)
This bachelor’s thesis deals with the problems of defects that occur in steel castings. First, the use of steel in the foundry industry and the development of classification of casting defects are described. Furthermore, it defines the term ‘casting defect’ and its division. The main part of the thesis focuses on the most frequent defects in steel castings. The aim of this literature search is to describe the casting defects and their causes and to present possible precautions against their rise. Possible ways of removing the casting defects are discussed as well as their repairs.

Optimation of heavy steel castings
Pernica, Vítězslav ; Veselý, Pavel (referee) ; Šenberger, Jaroslav (advisor)
Diploma thesis deal with definnig the casuses of stell castings defects in the DSB EURO s.r.o Foundry. The main target is to optimise technological parameters for avoiding the surface casting defects. The first stage is the identification of the defects, describing of the main reasons and mechanic. Defect quantification is make from measuring of area and volume of the mended defects. In association with surface defects, the number of the crackings was observed. Finally there are suggested correction actions based on the previous investigation.
