黄山无缝钢管的生产与应用

发布时间:2019-08-01  
2017-02-20 黄山无缝钢管按生产方法不同可分为热轧管、冷轧管、冷拔管、挤压管等。下面山东黄山无缝钢管厂为您详细介绍一下:
Seamless steel pipe according to the different production methods can be divided into hot rolling pipe, cold rolled, cold drawn tubes, extruded tube, etc.Under the shandong seamless steel pipe for you explain it in detail:
1、热轧黄山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。******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黄山无缝钢管是较先进的方法。
1, hot-rolled seamless pipe in automatic rolling on 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.
2、若欲获得尺寸更小和质量更好的黄山无缝钢管,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。
2, if you would get a smaller size and better quality seamless tube, 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.
3、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钢管。
3, extrusion method, the heating tube billet in airtight extrusion cylinder, perforated rods and extrusion, extrusion from smaller extrusion die.This method can produce smaller diameter of steel pipe.
根据用途不同分三类供应:a、按化学成分和机械性能供应;b、按机械性能供应;c、按水压试验供应。按a、b类供应的钢管,如用于承受液体压力,也要进行水压试验。
Divided into three categories according to utility supply: a, according to the chemical composition and mechanical properties of supply;B, according to the mechanical properties of supply;C, according to the supply water pressure test.According to a, b supply steel pipe, such as used for liquid under pressure, also must carry on the hydraulic pressure test.
黄山无缝钢管用途很广泛。一般用途的黄山无缝钢管由普通碳素结构钢、低合金结构钢或合金结构钢轧制,产量最多,主要用作输送流体的管道或结构零件。
Seamless steel tube USES a wide range.General-purpose seamless tube by ordinary carbon structural steel and low alloy steel or alloy structural steel rolling, most production, mainly used for conveying fluid pipe or structural components.
