On Line Box Type Four Silicon Nitride Rotor In-Line Rotory Degassing Equipment For Aluminum Alloy
Molten Aluminum Box type Double/Two Graphite Rotor in-line rotory degassing Equipment
1. Equipment Inroduce
• 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
nto scums.
Then aluminum melts outflow from the degassing unit outlet, thus realizing the purpose of continuous in-line refining.
• 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
f aluminum liquid, improved ensuring high efficiency and continuous stability Low-cost operation.
