有时我们会发现铝板的表面会出现一些缺陷，影响我们的使用和美观，这是什么原因呢?接下来，铝板生产厂家对铝板表面缺陷的原因分析如下:
　　Sometimes we will find some defects on the surface of aluminum plate, which will affect our use and beauty. What's the reason? Next, the aluminum plate manufacturer analyzes the reasons for the surface defects of aluminum plate as follows:
　　1、折(折)辊的形状不正确，如压光机轴承发热，使辊两端膨胀，压板结果在中间厚薄两边;平板的波量过大，使光量过大，造成压缩;板经过压光后，很容易折叠。板的两侧厚度大，容易产生压折。

　　1. The shape of the folding (folding) roller is not correct. For example, the bearing of the calender heats up, which makes the two ends of the roller expand, and the pressing plate results in the middle thick and thin sides; the wave amount of the flat plate is too large, which makes the light amount too large, causing compression; after the plate is calendered, it is easy to fold. The thickness of both sides of the plate is large, and it is easy to produce buckling.
　　2. 泡锭表面不平，有污物，装前未清洗干净;蚀刻后铸块和铝复合板表面有蚀刻和水洗的残留痕迹;加热时间过长或温度过高，铸块表面氧化。
　　2. The surface of foam ingot is uneven and dirty, which was not cleaned before installation; after etching, there are traces of etching and water washing on the surface of ingot and aluminum composite plate; if the heating time is too long or the temperature is too high, the surface of ingot will be oxidized.
　　3.铸坯热轧时，压力过大，锭端开裂;铸件块受热过高或过低。
　　3. When the billet is hot rolled, the pressure is too high and the ingot end cracks; the heating of the casting block is too high or too low.
