0. 10V)during hot rolling have been simulated by thermal simulator Cleeble- 1500.It wag found by test that with heating temperature increasing from 950 ℃ to1100 ℃ the austenite grain size in steel increased from 25.7μm to 84.3 μm;with heating temperature at 1000~1050 ℃ the austenite grain size was64.0~62.8 μm
it is available to control quality and ensure stable properties of steel rolled at the temperature range; with cooling rate increasing from 0.25 ℃/s to2 ℃/8
the tensile strength of steel F45MnV rolled with deformation 70% and finish rolling at 900 ℃ increased from 815 MPa to 960 MPa.
