摘　　要：探讨了不同轧制工艺对Q345钢40、25、14 mm厚规格板组织性能的影响。结果表明:对于40mm和25 mm厚的Q345钢采用控制轧制方式,对于14 mm厚规格板采用任意轧制方式,均可得到较好的综合性能。不同板厚的钢板,由于冷却速度不同造成钢板越薄,韧性越差。The effect of rolling technologies on the structures and properties of Q345 plates with different thickness（40 mm,25 mm,14 mm） are discussed in this paper.The results showed that good comprehensive properties for Q345 plates with different thickness can be gained with different rolling technologies： for 40 mm and 25 mm thick plate,controlled rolling technology should be adopted,for 14 mm thick plate,however,only common rolling technology is needed.The thinner of plate,the higher its intension and the worse its toughness,which is caused by the difference of cooling speed for different thickness plates.
