无缝钢管的生产方法
2020-12-15
  今天山东无缝钢管厂来和大家介绍一下无缝钢管的生产方法:
  Today, as an introduction to shandong seamless tube mill and seamless steel tube production methods:
  a、挤压法即将加热好的管坯放在密闭的挤压圆筒内,穿孔棒与挤压杆一起运动,使挤压件从较小的模孔中挤出。此法可生产直径较小的无缝钢管。
  A, extrusion method is a good heating tube billet are put in airtight extrusion cylinder, perforated rods and extrusion, extrusion from smaller extrusion die.This method can produce small diameter seamless steel tube.
  b、若欲获得尺寸更小和质量更好的无缝钢管,必须采用冷轧、冷拔或者两者联合的方法。冷轧通常在二辊式轧机上进行,钢管在变断面圆孔槽和不动的锥形顶头所组成的环形孔型中轧制。冷拔通常在0.5~100T的单链式或双链式冷拔机上进行。
  B, if you would get a smaller size and better quality seamless steel tubes, must adopt the method of cold rolling, cold drawing or both combined.Cold rolling is usually conducted on two-high rolling mill, steel pipe in variable cross section round hole groove and motionless conical head of rolling in the annular groove.Cold drawing usually in 0.5 ~ 100 t single or double chain chain cold drawing machine.
  c、热轧无缝钢管一般在自动轧管机组上生产。实心管坯经检查并清除表面缺陷,截成所需长度,在管坯穿孔端端面上定心,然后送往加热炉加热,在穿孔机上穿孔。在穿孔同时不断旋转和前进,在轧辊和顶头的作用下,管坯内部逐渐形成空腔,称毛管。再送至自动轧管机上继续轧制。最后经均整机均整壁厚,经定径机定径,达到规格要求。利用连续式轧管机组生产热轧无缝钢管是较先进的方法。
  C, hot-rolled seamless steel tubes in automatic pipe mill production unit.Solid billet through inspection and clear the surface defects, cut into the required length, centering on the tube billet perforation end face, and then sent to a heating furnace, punched on the punch.In perforated revolve and progress at the same time, under the action of roll and head, tube billet internal cavity formed gradually, according to the capillary.Then sent to automatically continue rolling mill.Finally approved by reeling mill all the whole wall thickness, the sizing sizing machine, to meet the specification requirements.Hot rolled seamless steel tube production by continuous rolling pipe unit is a more advanced method.
