不锈钢铁皮风管加工难点

由于不锈钢风管强度低，生产完成后需求按规定加固风管。镀锌螺杆内支撑加固常用的加固形式，加固螺杆直径不小于8mm。需要指出的是，如果螺杆穿管板不注意密封处理，会造成系统运行漏风的隐患。加强内部支撑时，在管壁两侧加垫圈并密封(涂上密封剂)，这一步尤为重要，因为这一步在施工过程中容易被忽视或偷工减料。下面通风管道厂家小编为大家介绍不锈钢风管加工难点：

Due to the low strength of stainless steel air duct, the air duct needs to be reinforced according to the regulations after production. Galvanized screw internal support reinforcement is a common reinforcement form, and the diameter of the reinforcement screw shall not be less than 8mm. It should be pointed out that if the screw passes through the tubesheet and does not pay attention to the sealing treatment, it will cause the hidden danger of air leakage in the operation of the system. When strengthening the internal support, add gaskets and seal (apply sealant) on both sides of the pipe wall, which is particularly important because it is easy to be ignored or cut corners in the construction process. The following is a brief introduction to the processing difficulties of stainless steel air duct:

1.不锈钢风管加工硬化严重。奥氏体不锈钢和一些高温合金不锈钢是奥氏体组织，切割时容易加工硬化。加工硬化倾向于比普通碳钢高几倍，刀具在加工硬化区切割，使用寿命缩短。

1. Severe work hardening of stainless steel air duct. Austenitic stainless steel and some superalloy stainless steel are austenitic structures, which are easy to work harden when cutting. Work hardening tends to be several times higher than that of ordinary carbon steel, and the service life of the tool is shortened when cutting in the work hardening area.

   
   

2.切割力大，切割温度高。本实用新型材料强度高，切削时切向应力大，塑性变形大，切削力大。此外，材料导热性差，导致切削温度升高，高温往往集中在刀片附近狭窄的区域，从而加速磨损。

2. Large cutting force and high cutting temperature. The utility model has the advantages of high material strength, large tangential stress, large plastic deformation and large cutting force. In addition, the poor thermal conductivity of the material leads to the increase of cutting temperature, and the high temperature is often concentrated in the narrow area near the blade, thus accelerating wear.

3.易粘刀。奥氏体不锈钢和马氏体不锈钢具有切屑强、切削温度高的特点。当强韧性切屑流经前刀面时，会出现粘合、熔焊等粘刀现象，影响加工配件表面的粗糙度。

3. Easy to stick knife. Austenitic stainless steel and martensitic stainless steel have the characteristics of strong chip and high cutting temperature. When the strong and tough chips flow through the rake face, there will be sticking phenomena such as bonding and fusion welding, which will affect the surface roughness of machined accessories.

4.刀具磨损会加速。上述材料一般含有高熔点、高塑性、高切削温度，加速磨损，频繁更换磨刀，影响生产效率，提高使用成本。主要是降低切割线速度和进给量。使用特殊的不锈钢或高温合金加工工具，钻，钻孔、攻丝或内冷。

4. Tool wear will accelerate. The above materials generally contain high melting point, high plasticity and high cutting temperature, accelerate wear, and frequently replace the grinding tool, which will affect the production efficiency and improve the use cost. It is mainly to reduce the cutting line speed and feed rate. Use special stainless steel or superalloy processing tools, drilling, drilling, tapping or internal cooling.

不锈钢管与共板式法兰风管是两种不同类型的风管，且有较大的差别。一，外观上，前者是圆形，后者是长方形。二，不锈钢螺旋风管在安装时，可能会使用法兰这一部件，而共板法兰风管，它是自带的法兰，因此，无需法兰。另外，在管道长度方面，两者也是不同的。

Stainless steel pipe and common plate flange air pipe are two different types of air pipes, and there are great differences. 1、 In appearance, the former is round and the latter is rectangular. 2、 When installing the stainless steel spiral air duct, the flange may be used, while the common plate flange air duct is its own flange, so there is no need for flange. In addition, in terms of pipe length, the two are also different.
