從生產過程來看,6061合金從半連續鑄錠、均勻化、鋸切、銑面、包鋁、加熱、熱軋、退火、冷軋、退火、冷軋、固溶處理、時效處理,到剪切、矯平、檢驗、涂油包裝的這一系列的工藝流程,構成了6061合金生產的完整步驟。
From the production process, from the 6061 alloy semi continuous casting, homogenization, sawing, milling, aluminum, heating, hot rolling, cold rolling, cold rolling, annealing, annealing, solid solution treatment, aging treatment, to cut, straightening, inspection, oiling and packaging of this series of process, constitute a complete procedure 6061 alloy production.
6061鋁板的生產工藝已非常成熟目前,目前,國內從事6061合金生產的廠家就有數十家,而河南明泰鋁業就是其中一個具有代表性的領軍企業。
6061, the production technology of aluminum plate has been very mature. At present, there are ten domestic enterprises engaged in the production of 6061 alloys, and Henan Ming Tai aluminum industry is one of the representative leading enterprises.
6061鋁板是6系的重要產品,因此,明泰鋁業設置了精準的生產控制,嚴格的質量檢測,來保證產品的工藝成熟,性能優越。例如,在進行質量檢測時,就對6061鋁板三個關鍵指標進行了精準檢測。一是組織細小、性能均勻。
6061 aluminum plate is an important product of the 6 department. Therefore, Ming Tai aluminum has set up precise production control and strict quality inspection to ensure that the product's technology is mature and its performance is superior. For example, in quality testing, three key indicators of 6061 aluminum plates are accurately tested. One is small tissue and uniform performance.
特別是對于超厚板,要求厚度方向上的性能均勻,不能有較大的性能波動,對于中厚板、薄板,在長度、寬度上同樣不能存在較大性能波動;二是尺寸精度較高。主要包括厚度精準和寬度精準,尤其是難度較大要求很嚴的厚度精度,將直接影響到使用性能和后續加工;三是板形良好。板形包括平直度和板凸度。因為二者對后續加工有很大影響,并且不可逆。
Especially for super thick plate, the thickness direction performance is uniform, and there is no greater performance fluctuation. For medium plate and thin plate, there is no big performance fluctuation in length and width, and the two is high dimensional accuracy. It mainly includes thickness accuracy and width accuracy, especially the thickness accuracy which is most difficult and strict. It will directly affect the performance and subsequent processing. Three, the shape is good. The shape of the plate consists of flatness and plate convexity. Because the two have a great impact on the subsequent processing, and irreversible.
6061鋁合金常用狀態有T6和T651,一般情況下,T6的內應力會比較大,加工會變形。因此,較適合加工的狀態是T651,T651狀態是在T6的基礎上進行拉伸,消除內應力,是經過熱處理預拉伸工藝的高品質鋁合金產品。
6061 aluminum alloys are commonly used in the state of T6 and T651. In general, the internal stress of T6 will be larger and the processing will be deformed. Therefore, the most suitable state for processing is T651. T651 state is stretched on the basis of T6 to eliminate internal stress. It is a high quality aluminum alloy product after heat treatment and pre stretching process.
6061-T651鋁板強度不能與2系、7系合金產品相比,但是,由于其鎂硅元素存在,因此,6061鋁板具備的焊接性、耐蝕性和冷加工性,可陽極氧化著色,也可進行涂漆,是一種使用范圍廣泛的合金,在建筑裝飾領域也常常使用。
6061-T651 aluminum plate and 2 line, 7 strength alloy products compared, however, due to the presence of the magnesium silicon, therefore, 6061 aluminum has excellent weldability, corrosion resistance and cold workability, anodizing can also be painted, is a kind of alloy widely used, are often used in building decoration field.
鋁板在生產過程中,因為受熱和擠壓,造成晶體間密度不均勻,能量得不到完全釋放,積蓄在鋁板內部,這個能量稱為內應力。某些用戶的生產工藝(如加溫、折彎、深沖、拉伸等)會釋放出鋁板的內應力,造成鋁板彎曲、波浪紋、表面不平等,所以需要先釋放出鋁板的內應力。
Aluminum plate in the production process, because of heat and extrusion, resulting in uneven density between crystals, energy can not be fully released, accumulated in the aluminum plate, this energy is called internal stress. Some users' production processes (such as heating, bending, deep drawing, stretching, etc.) will release the internal stress of aluminum plates, causing the bending, waviness and surface inequalities of aluminum plates, so we need to release the internal stress of aluminum plates first.
