由于不锈钢风管强度低，生产完成后必须按规定加固风管。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 ducts, they must be reinforced according to regulations after production is completed. The commonly used reinforcement form for internal support reinforcement of galvanized screws, with a diameter of no less than 8mm. It should be pointed out that if the screw passes through the pipe plate without paying attention to sealing treatment, it will cause a hidden danger of air leakage during system operation. When strengthening internal support, it is particularly important to add gaskets and seal (apply sealant) on both sides of the pipe wall, as this step is easily overlooked or cut corners during the construction process. Below, the editor of the ventilation duct manufacturer will introduce the difficulties in processing stainless steel air ducts:
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。
Severe work hardening of stainless steel air ducts. Austenitic stainless steel and some high-temperature alloy stainless steel are austenitic structures that are prone to work hardening during cutting. Work hardening tends to be several times higher than ordinary carbon steel, and cutting tools cut in the work hardening zone, resulting in a shortened service life.
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。
High cutting force and high cutting temperature. This utility model has high material strength, high tangential stress during cutting, large plastic deformation, and high cutting force. In addition, the poor thermal conductivity of the material leads to an increase in cutting temperature, which is often concentrated in a narrow area near the blade, thereby accelerating wear.
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。
Easy to stick knife. Austenitic stainless steel and martensitic stainless steel have the characteristics of strong chip strength and high cutting temperature. When strong and ductile chips flow through the front cutting surface, adhesion, fusion welding, and other adhesion phenomena may occur, affecting the surface roughness of the processed parts.
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。
Tool wear will accelerate. The above materials generally contain high melting point, high plasticity, high cutting temperature, accelerated wear, frequent replacement of grinding tools, which affects production efficiency and increases usage costs. Mainly to reduce the cutting line speed and feed rate. Use special stainless steel or high-temperature alloy processing tools to drill, drill, tap, or internally cool.
