Aluminum purification filter box has been widely used at home and abroad, including aluminum foil and PS version, can supply, aviation materials, etc.<\/span><\/p>\n

\u0627\u0644\u0640 filtration of liquid aluminum<\/a> includes surface filtration and internal filtration.<\/span> Surface filtration refers to the deposition of solid impurities mainly on the surface of the filter medium.<\/span> Internal filtration refers to the inclusions in liquid aluminum flow along the winding channels and pores in the filtration medium and are directly intercepted and absorbed.<\/span> Sedimentation, strong adhesion to the hole wall, strong adhesion to the hole wall.<\/span> With the filtration process, the effective filtration cross-sectional area of the channel gradually decreases, the permeability decreases, and the filtration accuracy increases.<\/span> The ceramic filter plate is internally filtered.<\/span><\/p>\n

At present, aluminum alloy processing plants at home and abroad have applied advanced aluminum purification filter box, mainly ceramic plate filter device, deep bed filter device, filter box device.<\/span> Since the first aluminum alloy foam filter was successfully studied in the 1970s, ceramic foam filter technology has developed rapidly and is widely used in aluminum processing plants.<\/strong><\/span><\/p>\n

\"Aluminum<\/p>\n

The aluminum purification filter box absorbs the cylinder shape and heat exchange technology of the chemical industry.<\/span> After being applied to the aluminum casting industry, the filtration area is increased and the filtration efficiency is improved by a large number of tube assemblies under the condition of constant flow of liquid metal.<\/span> Mainly meet the quality requirements of aircraft, automobile, disk, aluminum foil, cans and other high precision products.<\/span><\/p>\n

Advantages of Aluminum Filter Box<\/span><\/strong><\/p>\n

1. It can be used directly at room temperature without worrying about thermal shock.<\/span><\/p>\n

2. No thermal expansion, low thermal conductivity.<\/span><\/p>\n

3. Can float in aluminum, reducing the possibility of refractory inclusions.<\/span><\/p>\n

4. Special non-stick aluminum fused quartz is used as aggregate, with good thermal shock resistance, high strength, durability and thermal conductivity.<\/span><\/p>\n
