EFFECTS OF INCLUSION ON DRAWING PROPERTY OF HP295 CYLINDER STEEL
-
摘要: 通过对HP295焊瓶钢制作的钢瓶封头缺陷进行分析,找到了影响钢瓶封头拉延性能的原因。结果表明,拉延焊瓶封头出现开裂是由于钢中集中分布的稀土夹杂物所致。皱折缺陷与钢中存在带状组织、钢板厚度不均以及拉延工艺有关。Abstract: The influencing factors of drawing properties for the cylinder end-heads were analyzed by checking out the defect of cylinder end-heads which made of HP295 steel.Resultsshow that the crack at cylinder end-heads in drawing process is due to the concentrated RE inclusion in the steel. And its wrinkle defect is related to banding texture in the steel, uneven sheet thickness and drawing parameters.
