不少厂家有过这样的经历，当雨水芘子运输采购商后，雨水芘子外形和形状跟图纸的尺寸有些出入，甚有的发生了严重的变形。例如包边弯曲变形，对角线差距很大，横杆开焊等等。这就是“雨水芘子变形”，这时采购商往往会主观的认定就是厂家生产产品的质量差,严重的还会发生法律纠纷。那么产生山东雨水芘子变形的原因是什么呢？又如何避免呢？

Many manufacturers have had such experiences that when rainwater pyrene is transported to the purchaser, the shape and shape of rainwater pyrene are somewhat different from the dimensions on the drawing, and some even have serious deformation. For example, the wrapping is bent and deformed, the diagonal line gap is large, and the cross bar is open for welding. This is called "rain pyrene deformation". At this time, the purchaser often subjectively determines that the quality of the products produced by the manufacturer is poor, and in serious cases, legal disputes may arise. So what is the reason for the deformation of pyrenes in Shandong rainwater? How to avoid it?

1、雨水芘子做热浸锌表面处理时，雨水芘子遇高温多少也会有变形的现象。如果雨水芘子在焊成以后，有很强的内应力的情况下，这时就会发生严重的变形。

1. When the rainwater pyrene is subjected to hot dip galvanizing surface treatment, the rainwater pyrene will deform to some extent when exposed to high temperatures. If the rain pyrene has a strong internal stress after welding, serious deformation will occur.

2、雨水芘子基体中的内应力，如果在焊接雨水芘子的时候，没有把扁钢校直，而是把把扁钢直接放在模上焊接。表面上看起来是直的，实际上这时雨水芘子产生了比较强的内应力。如果再加上较强的外力作用（如比遇高温、摔打、挤压），内应力会表现出来，雨水芘子外形就变成水平的弓形了。

2. The internal stress in the rain pyrene matrix. If the flat steel is not straightened when welding the rain pyrene, instead, the flat steel is directly placed on the mold for welding. On the surface, it looks straight, but in fact, the rain pyrene produces relatively strong internal stress. If combined with strong external forces (such as high temperatures, blows, and squeezing), the internal stress will show up, and the shape of the rain pyrene will become a horizontal arch.

3、雨水芘子运输时尽量避免摔打、挤压和撞击。

3. When transporting rainwater pyrene, try to avoid hitting, squeezing, and hitting.

如何避免雨水芘子产生变形呢？

How to avoid rain pyrene deformation?

1、在焊接雨水芘子的时候，应该把扁钢校直后才能焊接。

1. When welding rainwater pyrenes, the flat steel should be straightened before welding.

2、在酸洗和热镀锌之前对雨水芘子进行去除内应力处理，在现代化工业生产中，一般不会产生此类问题。

2. Internal stress removal of rainwater pyrenes prior to pickling and hot galvanizing is generally not a problem in modern industrial production.

3、雨水芘子底座少得放三个，在两端和中间的部位放置即可，千万不能只放在两端，不放中间。上面压的雨水芘子多了会导致变形，使其变得不同一水平面上了。

3. The minimum number of rainwater pyrene bases is three, which can be placed at both ends and in the middle. Never only place them at both ends without placing them in the middle. "Too much rain pressure can cause deformation, making it different from the horizontal.".

4、在运输过程中放平稳，使其受力均匀，在装车卸车中不易用力摔打，应该轻抬轻放，做到以上这些就不会发生雨水芘子变形的情况了。

4. During transportation, it should be placed smoothly and evenly, making it difficult to force during loading and unloading. It should be lifted and handled gently, so that the deformation of rain pyrene particles will not occur.
