Manufacturing, structure and properties of cast iron with globular graphite produced on electric furnaces
Tvrdoň, Tomáš ; Pernica, Vítězslav (referee) ; Záděra, Antonín (advisor)
The diploma thesis deals with the technology of production of ductile iron with lower production costs. The thesis takes into account quality in terms of internal structure and mechanical properties. The thesis consists of two parts. The first part is about theoretical analysis of the topic of graphite cast irons with a more detailed discussion of the chemical composition, structure and properties of ductile iron. The experimental part deals with the production of ductile iron on electric arc and induction furnaces with different metall charging. Subsequently, the structures and mechanical properties of the ductile iron produced on these two melting aggregates are compared. An important part of this work is also an economic evaluation, where the proposed variants are compared in terms of metall charging and used melting aggregates.
