不少廠家有過這樣的經歷，當雨水芘子運輸至采購商后，雨水芘子外形和形狀跟圖紙的尺寸有些出入，甚至有的發生了嚴重的變形。例如包邊彎曲變形，對角線差距很大，橫桿開焊等等。這就是“雨水芘子變形”，這時采購商往往會主觀的認定就是廠家生產產品的質量差,嚴重的還會發生法律糾紛。那么產生山東雨水芘子變形的原因是什么呢？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、雨水芘子做熱浸鋅表面處理時，雨水芘子遇高溫多少也會有變形的現象。如果雨水芘子在焊成以后，有很強的內應力的情況下，這時就會發生嚴重的變形。

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、雨水芘子基體中的內應力，如果在焊接雨水芘子的時候，沒有把扁鋼校直，而是把把扁鋼直接放在模上焊接。表面上看起來是直的，實際上這時雨水芘子產生了比較強的內應力。如果再加上較強的外力作用（如比遇高溫、摔打、擠壓），內應力會表現出來，雨水芘子外形就變成水平的弓形了。

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、雨水芘子運輸時盡量避免摔打、擠壓和撞擊。

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

如何避免雨水芘子產生變形呢？

How to avoid rain pyrene deformation?

1、在焊接雨水芘子的時候，應該把扁鋼校直后才能焊接。

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

2、在酸洗和熱鍍鋅之前對雨水芘子進行去除內應力處理，在現代化工業生產中，一般不會產生此類問題。

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個，在兩端和中間的部位放置即可，千萬不能只放在兩端，不放中間。上面壓的雨水芘子多了會導致變形，使其變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、在運輸過程中放平穩，使其受力均勻，在裝車卸車中不易用力摔打，應該輕抬輕放，做到以上這些就不會發生雨水芘子變形的情況了。

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.
