随变形量和变形温度的增加

钢中晶粒尺寸减小

Abstract

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.
