鋁卷在高溫冷卻后會出現(xiàn)卷曲問題的原因

來源:http://www.kangyanghua.com/ 發(fā)布時間:2023-02-28

在鋁卷制作的過程中,為了幫助改變它的形狀,我們是需要對它進(jìn)行高溫加熱處理的,在高溫的狀態(tài)下它就會比較軟,其形狀也比較容易發(fā)生一些變化,在形狀調(diào)整好之后,就可以將它的溫度給降低下來,使其保持一定的硬度,但是有些情況,在高溫冷卻完成之后,鋁卷會出現(xiàn)一些卷曲問題,這是什么原因呢?鋁卷加工廠家下面為您講解一番:
In order to help change the shape of aluminum coil, we need to heat it at high temperature. Under high temperature, it will be soft and its shape is easy to change. After the shape is adjusted, its temperature can be reduced to maintain a certain hardness. However, in some cases, after the completion of high temperature cooling, the aluminum coil will have some curling problems, What is the reason? The aluminum coil processing factory will explain to you:
冷卻時會出現(xiàn)彎曲現(xiàn)象,原因為:
Bending will occur during cooling due to:
一般風(fēng)冷的條件下,鋁卷的各個部位與空氣接觸的換熱系數(shù)均持平,但因為壁厚或形狀不一樣,各部位的散熱速度不均衡,造成厚壁部或空心管的散熱速度比薄壁部慢,終造成它在冷卻時會出現(xiàn)向空心部位或壁厚較厚的部位曲折的現(xiàn)象。
Under the condition of general air cooling, the heat transfer coefficient of each part of the aluminum coil in contact with the air is the same, but because of the different wall thickness or shape, the heat transfer rate of each part is uneven, resulting in the heat transfer rate of the thick wall or hollow tube is slower than the thin wall part, and finally the phenomenon that it will turn to the hollow part or the thicker part when cooling.

彎曲原因及過程如下:
The causes and process of bending are as follows:
1、薄壁部分溫度下降快,先產(chǎn)生收縮力,厚壁部分或空心管部分溫度下降慢,幾乎沒有收縮力;
1. The temperature of the thin-walled part decreases rapidly, and the shrinkage force is generated first. The temperature of the thick-walled part or the hollow pipe part decreases slowly, and there is almost no shrinkage force;
2、薄壁部分截面積較小,產(chǎn)生的收縮力較小,或被牽引機(jī)牽引力消除;
2. The section area of the thin-walled part is small, and the shrinkage force generated is small, or it is eliminated by the traction force of the tractor;
3、離開牽引機(jī),溫度繼續(xù)下降;
3. After leaving the tractor, the temperature continues to drop;
4、厚壁部分或空心管部分截面積較大,隨著溫度下降逐漸產(chǎn)生較大收縮力,薄壁部分溫度已大幅下降,不再產(chǎn)生收縮力或收縮力較小;
4. The thick wall part or hollow pipe part has a large cross-sectional area, and gradually produces a large shrinkage force as the temperature decreases. The temperature of the thin wall part has decreased significantly, and no longer produces shrinkage force or the shrinkage force is small;
5、鋁卷截面上受到的收縮力大小不均,沿擠壓方向往厚壁部分或空心管部分彎曲。
5. The shrinkage force on the aluminum coil section is uneven, and it bends to the thick wall part or hollow pipe part along the extrusion direction.
