Anti-sticking resistance is an important property to avoid deep cracks for hot strip mill work roll materials, especially in the later stands where mill incidents like cobble are likely to occur. Effect of microstructure components on anti-sticking property was investigated with cast steel and iron samples using friction thermal shock test. Graphite was found to show higher effect than carbides, although they also show preferable effect, depending on its carbide type.

72nd World Foundry Congress, WFC 2016 36 - 37 2016.05

Language：English Publishing type：Research paper (international conference proceedings)

The effect of Si content on the ferrite-to-austenite transformation during austenitization in spheroidal graphite cast iron with a ferrite matrix was investigated. In this study, ferritic ductile cast irons with two different Si contents, 2.3 mass%Si (JIS-FCD400) and 3.8 mass%Si (SSFDI), were used. Microstructural observation revealed that the rate of the ferrite-to-austenite transformation for SSFDI was slower than for FCD400. In addition to the experiments, a simulation of the austenitization was performed for FCD and SSFDI using the DICTRA software package employing kinetic and thermodynamic databases. The simulations reproduced the experimental results on the austenitization behavior for both FCD and SSFDI well.
