    冷拔无缝钢管切割中普遍用到的方法

    冷拔无缝钢管无缝钢管的厚壁是很厚的一种的常见的类型,它是厚壁钢管的一种特殊的材质,对于冷拔无缝钢管而言更重要的是要保证最基本的使用和发挥更重要的性能。冷拔无缝钢管无缝钢管的重要的材质,它的硬度是比较大的,一般在切割的时候是比较费劲的,要掌握切割的技巧和方法,这样的话冷拔无缝钢管才能够切割成功,才能够不会伤到人。为了安全进行切割冷拔无缝钢管,建议这样进行操作:

    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.机械切割采用外部安装和内部安装两种,其采用车刀加工原理对管口进行切断和坡口加工,单机跨度大,可加工厚度大,废料少,无污染,加工过程不产生高温,不影响管道材质,有利于焊接的进行。水切割通过高压泵和金刚砂共同作用加工管道,其切口干净,加工跨度大,但是其效率低,加工厚度受限因素严重。

    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 pipeline 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.氧气乙炔焰切割,通过调节氧气阀门和乙炔阀,可改变氧气和乙炔的混合比例得到三种不同的火焰: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.离子切割,等离子切割配合不同的工作气体可以切割各种氧气切割难以切割的金属,尤其是对于有色金属(不锈钢、铝、铜、钛、镍)切割效果更佳;其主要优点在于切割厚度不大的金属的时候,等离子切割速度快,尤其在切割普通碳素钢薄板时,速度可达氧切割法的5~6倍、切割面光洁、热变形小、较少的热影响区。

    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.

    以上这些方式也是在冷拔无缝钢管切割中普遍用到的。冷拔冷拔无缝钢管一定要选择适合的切割工具,不然容易造成冷拔无缝钢管的损坏了浪费。

    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.
