冷拔無縫鋼管切割中普遍用到的方法

冷拔無縫鋼管是無縫鋼管的厚壁是很厚的一種的常見的類型，它是厚壁鋼管的一種特殊的材質，對於冷拔無縫鋼管而言更重要的是要保證最基本的使用和發揮环氧地坪更重要的性能。冷拔無縫鋼管是無縫鋼管的重要的材質，它的硬度是比較大的，一般在切割的時候是比較費勁的，要掌握切割的技巧和方法，這樣的話冷拔無縫鋼管才能夠切割成功，才能夠不會傷到人。為瞭安全進行切割冷拔無縫鋼管，建議這樣進行操作：
Cold-drawn seamless steel pipe is a common type of thick-walled seamless steel pipe. It is a special material of thick-walled steel pipe. For cold-drawn seamless steel pipe, it is more important to ensure the most basic use and play a more important role. Cold-drawn seamless steel pipe is an important material of seamless steel pipe, its hardness is relatively large, generally in the cutting time is more arduous, to master the cutting skills and methods, so that cold-drawn seamless steel pipe can be successfully cut, can not hurt people. In order to cut cold-drawn seamless steel pipe safely, it is suggested that the operation be carried out as follows: 1.機械切割采用外部安裝和內部安裝兩種，其采用車刀加工原理對管口進行切斷和坡口加工，單機跨度大，可加工厚度大，廢料少，無污染，加工過程不產生高溫，不影響管道材質，有利於焊接的進行。水切割通過高壓泵和金剛砂共同作用加工管道，其切口幹凈，加工跨度大，但是其效率低，加工厚度受限因素嚴重。
1. Mechanical cutting adopts external installation and internal installation. It adopts turning tool processing principle to cut and groove the pipe mouth. It has large span, large Machinable thickness, less waste, no pollution, no high temperature in the processing process, no influence on pipe material, and is conducive to welding. Water cutting process pipeli彩色沥清地坪ne by high-pressure pump and diamond sand, its cut is clean, processing span is large, but its efficiency is low, processing thickness is seriously limited factors.
2.氧氣乙炔焰切割，通過調節氧氣閥門和乙炔閥，可改變氧氣和乙炔的混合比例得到三種不同的火焰：中性焰、氧化焰和碳化焰。
2. Oxyacetylene flame cutting, by adjusting the oxygen valve and acetylene valve, can change the mixing ratio of oxygen and acetylene to get three different kinds of flame: neutral flame, oxidation flame and carbonization flame.
3.離子切割，等離子切割配合不同的工作氣體可以切割各種氧氣切割難以切割的金屬，尤其是對於有色金屬(不銹鋼、鋁、銅、鈦、鎳)切割效果更佳;其主要優點在於切割厚度不大的金屬的時候，等離子切割速度快，尤其在切割普通碳素鋼薄板時，速度可達氧切割法的5~6倍、切割面光潔、熱變形小、較少的熱影響區。
3. Ion cutting, plasma cutting with different working gases can cut all kinds of hard-to-cut metals, especially for non-ferrous metals (stainless steel, aluminium, copper, titanium, nickel); its main advantage is that when the thickness of metal is not large, plasma cutting speed is fast, especially in general cutting. In the case of carbon steel sheet, the cutting speed can be 5-6 times as fast as that of oxygen cutting method, the cutting surface is smooth, the thermal deformation is small and the heat affected zone is less.
以上這些方式也是在冷拔無縫鋼管切割中普遍用到的。冷拔冷拔無縫鋼管一定要選擇適合的切割工具，不然容易造成冷拔無縫鋼管的損壞瞭浪費。
These methods are also commonly used in cold-drawn seamless steel tube cutting. Cold-drawn seamless steel pipe must choose suitable cutting tools, otherwise it is easy to cause damage and waste of cold-drawn seamless steel pipe.
