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. Aluminum alloy melting furnace
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. Alloy elements
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.
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. Profile extrusion
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.
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.
