采用不同加热温度对E36船体结构钢板进行热弯曲试验。结果表明,E36船体结构钢板具有良好的水火弯板工艺适应性,水火弯板后钢板性能均能满足要求,其强度略有升高,塑性略有下降,加热温度750℃时冲击韧性变化不大,加热温度800℃时冲击韧性显著降低,这可能是由于较高加热温度导致了焰道中心晶粒粗大所致。 Heat bending tests on E36 steel hull structures with different heating temperatures. The results show that the E36 hull structural steel has good adaptability to the fire and water bending process, and the performance of the steel after the fire and water bending can meet the requirements. The strength of the E36 hull structure slightly increases and the plasticity decreases slightly. The impact toughness changes little when the heating temperature is 750 ℃ , The impact toughness is significantly reduced when the heating temperature is 800 ℃, which may be due to the higher heating temperature caused by the coarse grains in the center of the flame channel.
