The results show that there is no big change of the range of soft reduction gradient and soft reduction rate for casting steel grades as low carbon, low carbon peritectic, peritectic and medium carbon, which change from 0.26 to 0.16mm/m and 0.37 to 0.22mm/min respectively. The average soft reduction gradient and average soft reduction rate almost have no change as the steel grade changes, which keep the value of 0.21mm/m and 0.29mm/min respectively. It also can be concluded that the soft reduction amount was influenced by steel grade greatly, and it became larger with the increase of temperature range between liquidus temperature and solidus temperature.
