The metal rheology of steel 20CrMnTiH during rolling process of 430 mm x 300 mm casting bloom to Φ130 mm steel product is simulated by bloom pin-shooting test. Test results show that in the direction of parallel to pin-shooting
the pin is deformed and extend-spread to flat type
and in the direction of perpendicular to pin-shooting
the pin is compressed to sickle-type bend
therefore the effect of rolling process on macro-carbon segregation in cross section of finishing products is not obvious.
