Aluminum Filtration Equipment -

Aluminum filtration equipment is designed for getting clean molten aluminum. Molten metal cleanliness is one of the major challenges for most foundries. They have to produce slabs containing enough hydrogen, alkali metals (mainly sodium) and inclusions to make their final products suitable for their end use. This is particularly important when the slab is rolled into thin sheets used to make beverage cans or foils. Molten metal cleanliness needs to be properly managed with the right aluminum filtration equipment and to ensure proper operation. AdTech offers online degassing and CFF filtration equipment.

Depending on the product, the next critical operation may be the degasser. There are many different types of degassers, but most rely on rotating rotors. The rotor injects chemically active reactants (usually chlorine or solid salt fluxes) mixed with carrier gases (such as argon or nitrogen) into the molten metal to form tiny bubbles. The key to operating such devices for optimal efficiency is the use of rotor design and practice, resulting in smaller bubble sizes and longer bubble under surface residence times.

The advanced high silicon melting technology is adopted in the Adtech on-line degassing device to prolong its service life. The degassing rotor, heater protection sleeve and thermocouple protection sleeve are all made of ceramic manufacturing technology, which can meet the requirements of high-precision aluminum production. The rotating rotor is made of sin. The working life is 2-5 years. It performs well in corrosion resistance, heat shock resistance, oxidation resistance, wear resistance and mechanical strength. The shaft diameter is 60mm and the head diameter is 200mm, so the mixing resistance should be reduced. The velocity is designed at 450-550 R / m to crush the bubbles and disperse them evenly into the aluminum. It is cost-effective when used for a long time.

AdTech CFF filtration is used to filter and purify molten aluminum and match with ceramic foam filters. It can filter inclusions and tiny particles in molten aluminum. It is especially suitable for casting high purity aluminum and high precision aluminum alloy. It has the advantages of heat resistance, oxidation resistance, corrosion resistance, rapid preheating, long service life and acid resistance.
