FEATURE OF SHAPING GRAPHITE IN
SYNTHETIC CAST IRON AT VACUUM MELTING

Zaporizkij national technical university

A study of graphite forming in synthetic iron during vacuum melting was conducted.
It is established that cast iron vacuum melting contributes its graphitization, has a positive
action on the graphite phase, improving the shape and distribution of graphite in the
metallic matrix. The saturation process of cast iron by carbon during vacuum melting is
accompanied by intensive deoxidation and the CO development, which, together with low
content of harmful impurities (sulfur, oxygen etc.) and high rate of crystallization,
contributes to changes in the graphite phase morphology from lamellar to spherical.

Keywords: synthetic cast iron, graphite shape, vacuum, carbon, gas bubbles
