分析吹氧管的材质化学成分

发布日期:2019/5/16 10:12:43 来源:http://pilotajans.com 点击:0

  一、 对原料材质的质量要求:吹氧管宝乐彩票平台的原材料,除必须达到普通高频电焊钢管原材料的基本要求外,还须满足以下几方的要求:

  1、化学成份:冶炼吹氧管宝乐彩票平台时,重点是提高钢的纯净度,减少钢中的非金属夹杂物的含量,硫和磷含量要小于0.03%,为了适应后步冷变形加工,硫含量******不要超过0.02%,因此要严格控制钢的化学成份。同时为保证产品具有良好的力学性能,冷弯、焊接等工艺性能,还需适当增加一些Nb、Ni、V等元素。

  2、吹氧管形状和尺寸:吹氧管轧制时,应采用AGC和板形控制系统,提高吹氧管厚度精度和板形精度。同时还要采用控制冷却方法,提高吹氧管 的强韧性。纵剪吹氧管宽度尺寸精度要求要控制,吹氧管边缘要无压痕和毛刺,以提高焊接质量。
