王卫华, 王文军, 刘洋, et al. Simulation Calculation on 250 ~ 320 mm Casting Slab during Stacking Slow Cooling Process[J]. Special Steel, 2013, 34(1): 13-15.DOI:
D36 and X70 etc steel grades is metal pretreatment-100 t converter-LF-RH-250 ~320 x 2 000 mm slab casting. As temperature of charging casting slab is 650 〜700 °C
because of AIN precipitates at grain boundary the claw-cracks of steel plate easily occur
and as the temperature of charging slab is controlled at 500 ~ 550 V. the claw-cracks of steel plate are avoided. The numerical simulation on temperature field and temperature dropping rate of staking slab has been carried out by ANSYS finite element method software. The model calculation results show that as 250 mm slab and 320 mm slab are respectively stacked for 12 h and 24 h
the surface temperature of slab at centre of stacking is less than 600 ℃
and the measured value at production situation conforms to the simulation result.
