ã€China Aluminum Industry Network】 Aluminum alloys on the market are thick and turbid, determining the quality of aluminum raw materials, the key is the following three elements, today Xiaobian to explain to us:
Aluminum alloy melting furnace
Smelting furnaces are also crucial. They are usually square-shaped furnaces (rectangular furnaces). The leading ones are circular furnaces. Some circular furnaces can deflect aluminum water. On the tonnage of one ton, two tons, five tons, ten tons, twenty-five tons and fifty tons of aluminum melting furnace. More advanced, in the following aluminum melting furnace and then add a static furnace, static furnace important for the manufacture of alloys, in this furnace slag degassing, standing, and then forging aluminum rods for kneading applications. In general, the furnace, regardless of the burning of thorium fuel, should have a chimney, and most of the exhaust gas slag generated during the burning of fuel can be discharged from the chimney. If the smokeless exhaust gas residue is completely melted in the aluminum water, the aluminum rod for kneading is cast, and there is a serious inclusion slag bubble inside. This is one of the reasons for the low quality of the aluminum raw material, which is also one of the reasons for the low price of aluminum. .
2. Alloy elements
Qualified formula made of alloys, can guarantee quality, otherwise how to process in the future, quality does not go up. In order to cut costs, some manufacturers use magnesium to a minimum to allow content. Some even worse, the content of magnesium is lower than the minimum required. As a result, the mechanical strength of aluminum profiles is very low, and it can be as simple as twisting with two hands and one bend. Commonly known as noodles are the same soft. This is one of the reasons why aluminum can be a few thousand dollars cheaper.
The standardized aluminum manufacturers have internal standards in the manufacture of alloy components, that is, within the scope of various elemental contents. Each plant has its own smaller scale, and the demand for aluminum, magnesium and silicon is very high. Strictly, each factory has its own data and is confidential.
3. Profile kneading
China's profile kneading machine has a wide variety of products and has a wide range of unevenness. It is also a world comparison. There is a factory-owned simple kneading machine, which can be transformed with a plastic extruder. There are a small amount of homemade products, followed by most of Japan, the United States, and Germany, with hydraulic and hydraulic pressure. In total, hundreds of kneading machines in China are all kinds. It is generally believed that Japanese, American, and German kneading machines are better. Good and poor kneading machines, the same cast rods, the amount of raw material extruded is by no means the same.
High quality and ordinary aluminum raw materials may be used to make things, which will lead to great errors in the amount of aluminum raw materials. In terms of things and skills to improve their own products, trust will certainly be more easily recognized by the industry than cheaper products.
