1.熱軋無縫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。

1 hot rolling seamless pipe production in general automatic tube mill. Solid tube blank check and clear the surface defects, cut into required length, in the tube hole end surface of centering, then sent to a heating furnace, in punch.

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。

In perforated while continuing to rotate and advance, in the roll and immediate action, tube gradually form a cavity, called capillary. Sent to the automatic tube rolling mill on rolling. Finally, all the machines are the whole wall thickness, diameter sizing machine, to meet the specifications.

利用連續式軋管機組生產熱軋無縫鋼管是較先進的方法。

It is an advanced method to produce hot rolled seamless steel tube by continuous rolling mill.

2.若欲獲得尺寸更小和質量更好的無縫管，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。

2 in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold usually in two roller mill, rolling ring groove tapered plug pipe in variable cross section circular slot and the composition of the. Cold drawing was usually in the 0.5 ~ 100T single chain or double chain drawbench.

3.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?？字袛D出。此法可生產直徑較小的鋼管。

3 extrusion method is about to heat the tube billet in the closed extrusion cylinder, the punching rod and the extrusion rod move together, so that the extrusion parts from the smaller die extrusion. This method can produce smaller diameter steel pipe.
