The effect of deformation (10% ~50%) and temperature (850 ~ 1 000 ℃) on pearlite
ferrite size and ratio in hot rolled Φ190 mm product of steel 27SiMn (/% : 0. 27C
1. 20Si
1. 25Mn
0. 015Mo
0. 021 Ti) for coal machine has been studied by using Gleeble-1500 thermal simulator. Results show that with increasing deformation and temperature the size of grains in steel decreases and the homogenization of grain size increases ; as the steel deforms at 950 °C with deformation 30%
the grain size of pearlite in steel is 18 ~42μm
the average size is 28 μm and the pearlite accounts to 54% of the total structure in steel 27SiMn.
