Abstract
The article investigates the thermal conditions of graphite phase precipitation in the working layer of the LPHND‑71 rolling roll, which affect its operational characteristics. During the study, the crystallization processes of the working layer made of alloyed cast iron (at 1200–1250 °C) under centrifugal force conditions were experimentally examined, as well as the pouring of the core with gray cast iron (1370–1450 °C). Using the SCM «PolygonSoft», the conditions for the primary precipitation of the graphite phase were simulated. The obtained data are of practical importance for optimizing production technology and increasing the service life of LPHND‑71 rolling rolls.
