Prediction of Metallurgic Quality of ICDP Material before Tapping

Popis výsledku v původním jazyce

ICDP (Indefinite Child Double Pour) irons designated for working layer of centrifugal rolls of rolling mill must have precisely defined properties. The monitored parameters of the ICDP irons are: chemical composition, the amount of graphite in a microstructure and hardness of base metal material. Precipitation of graphite in ICDP iron with ledeburitic basic metal compound is a complex process that can be controlled and managed with the usage of thermal analysis. On the basis of the evaluation of coolingcurve parameters of ICDP iron there is performed metallurgical adjustment of melting by adding elements supporting graphite or carbide formation into ICDP iron. The identified structural and mechanical properties of ICDP irons were correlated with recorded cooling curve. Subsequently, a methodology for control of the metallurgical adjustment of ICDP iron before tapping and pouring was proposed to ensure the desired microstructure and properties the ICDP iron.
