description: Subject of the final qualification work: "Production of large-capacity castings
from cast iron with spherical graphite (LLC "Foundry" PetrozavodskmashÂ»)Â»
In the course of this work, the production of castings at the Petrozavodskmash
foundry was studied. The technology of manufacturing large-capacity castings from
high-strength cast iron in the conditions of this production is analyzed. A
technological process for producing large-capacity castings "Slag bowl" from highstrength cast iron has been developed. The Gating-feeding system and casting-model
technology were designed. Modeling of the casting solidification process was
performed to identify possible defects and calculate the cooling time in the mold.
The process of melting high-strength cast iron in an induction crucible furnace and
processing in the liquid state of cast iron with spherical graphite was developed. The
required amount of charge materials is calculated for melting a given amount of
metal, followed by charging to the required chemical composition. The mold was
filled and the mold was kept at the temperature allowed for extraction. Cutting and
cleaning operations were performed for the subsequent acceptance of products by
the quality service. Mechanical properties and structure of cast iron were determined
from tidal and separately filled samples. A pilot casting "Slag bowl" was obtained,
the quality of which fully meets the requirements of technical documentation.
