我们都知道,铝板市场上良莠不齐,质量,价格,材质,工艺等等,存在着很大的问题,不是所有的产品都能保证质量优良,那么除了加工工艺,究竟还有哪些因素是影响质量的因素呢?
As we all know, there are many problems in the aluminum plate market, such as quality, price, material, technology and so on. Not all products can guarantee good quality. In addition to processing technology, what other factors affect the quality?
1.铝合金熔炼炉
1. Aluminum alloy melting furnace
熔炼炉一般用的多为方型炉(矩形炉),先进的为圆形炉(部分可倾斜倒铝水)。论吨位有一吨、二吨、五吨、十吨、二十五吨和五十吨熔铝形炉。在熔铝炉下面再加一个静置炉、静置炉重要配制合金用,可在此炉内除渣除气,静置,然后再铸造铝棒,以供挤压使用。一般炉子,均应有烟筒,燃料在燃烧过程中产生的废气废渣大部分可以从烟筒排出。如没烟筒废气废渣全部熔在铝水中,这样铸出供挤压用的铝棒,内部存在有严重的夹渣气泡,这是彩铝板质量低劣原因之一,这也是铝价便宜原因之一。
The square furnace (rectangular furnace) is usually used in smelting furnace, and the advanced one is round furnace (part of which can be inclined to pour aluminum water). In terms of tonnage, there are 1 ton, 2 T, 5 t, 10 t, 25 t and 50 t aluminum melting furnace. A static furnace is added under the aluminum melting furnace, which is important for alloy preparation. Slag and gas can be removed in this furnace, and then aluminum rods can be cast for extrusion. Generally, the furnace should have a chimney, and most of the waste gas and residue generated during the combustion of fuel can be discharged from the chimney. If there is no chimney, the waste gas and waste residue are melted in the aluminum water. In this way, there are serious slag inclusion bubbles in the aluminum rod for extrusion. This is one of the reasons for the poor quality of color aluminum plate and one of the reasons for the low price of aluminum.

 


2.合金元素
2. Alloy elements
有合格的配方制成的合金,才能保证质量。有的厂家为了减少成本,把镁的用量少到最少允许含量。更有甚者,把镁的含量低于允许的最少含量,致使铝型材机械强度很低,这就是彩铝板为什么能便宜几千元原因之一。
Only with the alloy made of qualified formula can the quality be guaranteed. In order to reduce the cost, some manufacturers reduce the amount of magnesium to the minimum allowable content. What's more, if the magnesium content is lower than the minimum allowable content, the mechanical strength of aluminum profiles is very low, which is one of the reasons why the color aluminum plate can be thousands of yuan cheaper.
正规的彩铝板厂家,在配制合金成份时,均有内部标准,就是在各种元素含量范围内,各厂有他们自己更小变化范围,铝、镁、硅三者之间比例要求很严,各厂有自己数据,相互保密。
Regular color aluminum plate manufacturers have internal standards when preparing alloy composition, that is, within the range of various elements, each factory has its own smaller range of variation. The proportion of aluminum, magnesium and silicon is very strict. Each factory has its own data and keeps each other confidential.
3.型材挤压
3. Profile extrusion
我国型材挤压机种类繁多,档次高低悬殊,也为世界之最。有工厂自己的简易挤压机,有用压挤塑料机改造的,有少量国产的,其次大部分是日本的,美国的和德国的,总之国内几百台挤压机五花八门。普遍认为日本、美国、德国挤压机较好。好和差的挤压机,同样的铸棒,挤出的型材质量决不二样。
There are many kinds of profile extruders in China, and their grades are very different, which is also the best in the world. There are some simple extruders of our own, some of which have been transformed by plastic extruders, and a small number of them are made in China. Most of them are Japanese, American and German. In short, there are hundreds of domestic extruders. It is generally believed that Japanese, American and German extruders are better. Good and bad extrusion press, the same casting bar, the quality of extruded profiles is no different.
往往有时候,彩铝板的质量不是我们能用肉眼所判断的,这就需要我们要通过专业的检测设备进行鉴别,优质与普通的铝材质或者炼制工具,都会造成铝材质量上面偏差很大,只有在工具、技术上来提升自己的产品,相信一定会比低廉的产品更易获得行业的认可。
Sometimes, the quality of color aluminum plate can not be judged by our naked eyes, which requires us to identify through professional testing equipment. High quality and ordinary aluminum materials or refining tools will cause great deviation in the quality of aluminum materials. Only by improving our own products in terms of tools and technology, I believe that it will be easier to obtain industry recognition than low-cost products.
