我們都知道,鋁板市場上良莠不齊,質量,價格,材質,工藝等等,存在著很大的問題,不是所有的產品都能保證質量,那么除了加工工藝,究竟還有哪些因素是影響質量的因素呢?
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.鋁合金熔煉爐
1. Aluminum alloy melting furnace
熔煉爐一般用的多為方型爐(矩形爐),的為圓形爐(部分可傾斜倒鋁水)。論噸位有一噸、二噸、五噸、十噸、二十五噸和五十噸熔鋁形爐。在熔鋁爐下面再加一個靜置爐、靜置爐重要配制合金用,可在此爐內除渣除氣,靜置,然后再鑄造鋁棒,以供擠壓使用。一般爐子,均應有煙筒,燃料在燃燒過程中產生的廢氣廢渣大部分可以從煙筒排出。如沒煙筒廢氣廢渣全部熔在鋁水中,這樣鑄出供擠壓用的鋁棒,內部存在有嚴重的夾渣氣泡,這是彩鋁板質量低劣原因之一,這也是鋁價便宜原因之一。
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,才能保證質量。有的廠家為了減少成本,把鎂的用量少到少允許含量。更有甚者,把鎂的含量低于允許的少含量,致使鋁型材機械強度很低,這就是彩鋁板為什么能便宜幾千元原因之一。
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.
正規的彩鋁板廠家,在配制合金成份時,均有內部標準,就是在各種元素含量范圍內,各廠有他們自己更小變化范圍,鋁、鎂、硅三者之間比例要求很嚴,各廠有自己數據,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.型材擠壓
3. Profile extrusion
我國型材擠壓機種類繁多,檔次高低懸殊,也為世界之。有工廠自己的簡易擠壓機,有用壓擠塑料機改造的,有少量國產的,其次大部分是日本的,美國的和德國的,總之國內幾百臺擠壓機五花八門。普遍認為日本、美國、德國擠壓機較好。好和差的擠壓機,同樣的鑄棒,擠出的型材質量決不二樣。
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.
往往有時候,彩鋁板的質量不是我們能用肉眼所判斷的,這就需要我們要通過的檢測設備進行鑒別,優質與普通的鋁材質或者煉制工具,都會造成鋁材質量上面偏差很大,只有在工具、技術上來提升自己的產品,相信一定會比低廉的產品更易獲得行業的認可。
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.
