Launder Type In-line Rotory Degassing Unit for Removing Hydrogen from Molten Aluminum

  The LDU has higher degassing efficiency because degassing rotors are mounted between the melting furnace and casting machine in the length direction of the launder and the degassing zone is partitioned into several parts for multilevel in-line degassing. The number of rotors depends on the flow rate of molten aluminum.

Usage:

The BDU Box type in-line rotor degassing unit is usually installed between the discharge outlet of the smelting furnace and the filter box. Melts flow into the BDU and rotate the rotor to break inert gases, forming a large quantity of dispersed bubbles, which then enter into the aluminum melts. After collision, capturing, surface adsorption and partial pressure action, the bubbles rise with gases and take hydrogen and oxide slags out of melts, making them into scums. Then, aluminum melts outflow from the degassing unit outlet, thus realizing the purpose of continuous in-line refining.
 

Equipment Features:

•BDU box-type in-line rotor degassing unit is designed based on the advantages of mainstream box-type degassing devices available in the market, with several key technologies, such as box sealing and anti-turbulence on the surface of aluminum liquid, improved ensuring high efficiency and continuous stability Low-cost operation.
