Crystalline order can be established relatively satisfactory solidification conditions, the crystalline grain size, mechanical properties and electrical conductivity are more favorable. No more than slabs of its kind on the difference in height direction on the mechanical properties, segregation is also smaller, faster cooling, Yantai wine together compacts, you can get a very fine crystal structure. Aluminum ingot surface should be smooth, no slag, cracks, holes, etc., Jinan wine together compacts, surface crack length of not more than 1.5mm, slag and wrinkles edge crack depth from the surface allowed more than 2mm, section should not have cracks , porosity and slag, slag less than lmm of no more than five. Aluminum ingot main deficiencies are: ① cracks. The reason is an aluminum liquid temperature is too high, too fast, increasing the residual stress; liquid aluminum silicon greater than 0.8%, the resulting molten aluminum-silicon with, and then generate some free silicon, increasing the thermal cracking of metal: or lack of cooling water. In the crystal surface roughness or no use of lubricants, the surface and the corner of the ingot also cracks. Depending on the content of alloying elements of aluminum sheet can be divided into: 1 ××× line of industrial aluminum (Al), 2 ××× Department of aluminum-copper alloy aluminum (Al - Cu), 3 ××× line of aluminum-manganese alloy aluminum (Al - Mn), Texas wine together briquetting, 4 ××× Department of aluminum-silicon alloy aluminum (Al - Si), 5 ××× Department of aluminum-magnesium alloy aluminum (Al - Mg), Shandong wine co compacts, 6 ××× Department of aldrey aluminum (AL - Mg - Si), 7 ××× Department of aluminum-zinc alloy aluminum [AL - Zn - Mg - (Cu)], 8 ××× Department of aluminum and other elements. Generally speaking, each series also followed by three, to have numbers or letters on each bit, the meaning is: The second digit indicates the number of controlled impurities; third, four-digit number represents the lowest percentage of aluminum aluminum content after the decimal point content. 2. The shape can be divided into: a round rod, square rod, hexagonal rod, etc. Yantai wine together compacts Shengxin scrap metal recycling, wine co-compacts recovered from Linyi City Shengxin scrap metal Limited. Yantai wine together compacts Shengxin scrap metal recycling, compact wine together Linyi City Shengxin scrap metal recycling Ltd.
