The Effect of Cooling Rate on the Properties of Alloyed Cast-Iron Sizing Roll

Directional heat transfer was investigated by temperature measurements in the casting and in the mould using thermocouples. Measurements were performed in operating conditions during pouring, solidification, and cooling of the casting. Total measurement time was 35.5 hours. After cutting, specimens were extracted for metalographic and hardness testing. Test results provided confirmation of directional heat transfer (directional cooling) that would ensure acquirement of a desired casting structure and mechanical properties.
