無縫鋼管的生產方法
2021-12-15
  今天山東無縫鋼管廠來和大家介紹一下無縫鋼管的生產方法:
  Today, as an introduction to shandong seamless tube mill and seamless steel tube production methods:
  a、擠壓法即將加熱好的管坯放在密閉的擠壓圓筒內,穿孔棒與擠壓桿一起運動,使擠壓件從較小的模孔中擠出。此法可生產直徑較小的無縫鋼管。
  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、若欲獲得尺寸更小和質量更好的無縫鋼管,必須采用冷軋、冷拔或者兩者聯合的方法。冷軋通常在二輥式軋機上進行,鋼管在變斷面圓孔槽和不動的錐形頂頭所組成的環形孔型中軋制。冷拔通常在0.5~100T的單鏈式或雙鏈式冷拔機上進行。
  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、熱軋無縫鋼管一般在自動軋管機組上生產。實心管坯經檢查并清除表面缺陷,截成所需長度,在管坯穿孔端端面上定心,然后送往加熱爐加熱,在穿孔機上穿孔。在穿孔同時不斷旋轉和前進,在軋輥和頂頭的作用下,管坯內部逐漸形成空腔,稱毛管。再送至自動軋管機上繼續軋制。最后經均整機均整壁厚,經定徑機定徑,達到規格要求。利用連續式軋管機組生產熱軋無縫鋼管是較先進的方法。
  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.
