Numerical Simulation on Thermal Stress Field in a Wide Slab Mould of Peritectic Steel Continuous Casting

摘要：

　　A numerical simulation of the thermal stress field of the solidified shell in the mold during continuous casting of peritectic steel slab was calculated.The results showed,owing to the volume contraction caused by the peritectic reaction,the thermal stress on the wide surface of the solidified shell was larger for the peritectic steel slab than that for the non-peritectic steel,and the maximum thermal stress on the wide face was at the 200~400mm position away from the central line.With increment of slab width,the thermal stress increased and the maximum value moved towards the central line.In addition,the thermal stress was also affected by the casting operation parameters.In the present work,the proper drawing speed was around 1.2m/min for the wide slab of 3200mm×150mm,with the cooling intensity of 5500L/min and the superheat degree of 15°C to 25°C.
