Remelting ingots common defects are: ① pores. Mainly due to the casting temperature, more gas in liquid aluminum, aluminum ingot surface pores (pinholes) and more, the surface dark, severe thermal cracking. ② slag. Mainly due to one hit residue without a net, causing the surface slag; second molten aluminum temperature is too low, causing internal slag. ③ ripple and flash. Mainly the operation is not fine, ingots do too much, or the resulting casting machine is not running smoothly. ④ cracks. Cold cracking mainly casting temperature is too low, resulting in less dense crystalline ingots, Shandong 104 rod manufacturers, resulting in loose even crack. High temperature thermal cracking caused by the casting. ⑤ segregation. When the cast alloy is mainly caused by uneven mixing. Recycling aluminum is aluminum and aluminum ingots as raw materials, Shandong 104 rod, add other elements in accordance with international standards or special requirements, Shandong 104 rod quotes, such as: silicon (Si), copper (Cu), magnesium (Mg), iron (Fe) ..., improved aluminum alloy casting, chemical resistance and lack of physical deployment out. In the earth's crust after oxygen and silicon ranked third. The density of aluminum is small, only 34.61% iron, 30.33% copper, it is also called the light metal. Aluminum is the world second only to iron and steel production and consumption of non-ferrous metals. The density of aluminum only 2.7103g / cm3, is about steel, copper or brass density 1/3. Since the light aluminum material, commonly used in the manufacture of automobiles, trains, subways, ships, aircraft, rockets, spacecraft and other sea and air transport, to reduce weight increase loading capacity. Shandong 104 rod, scrap metal recycling, Shandong rod 104 is recovered by the Linyi City Shengxin sell scrap metal Limited. Shandong 104 rod, scrap metal recycling, 104 Shandong Linyi City Shengxin rod sell scrap metal recycling Ltd. (shengxin.tz1288.com) this year introduced a new upgrade, the above picture is for reference only, please call this page or image on the telephone, to obtain the latest information, contact: Zhu new.
