The High Efficient Aluminium Purification Return Launder Type In-line Rotory Degassing Unit (LDU) has been designed to ensure a superior degassing efficiency. This is achieved due to the special placement of the degassing rotors, which are installed between the melting furnace and casting machine in the length direction of the launder. Moreover, the degassing zone is partitioned into several parts for multilevel in-line degassing, meaning that more effective purification is achievable. The number of rotors employed is based on the flow rate of molten aluminum, with multiple rotors available when needed. The combination of the secondary degassing rotor after the primary degassing rotor further improves gas bubbles removal, leading to a greater purification of aluminium. Consequently, these rotator degassing units present higher overall degassing efficiency compared to other units of the same kind.
High degassing efficiency, above 40%. Adopting multi-zone continuous degassing to increase the contact surface and contact time between bubbles and molten aluminum; adopting the sealed design to maintain an inert headspace above the molten aluminum surface during the entire casting period to prevent more slag to eliminate secondary pollution and improve degassing efficiency.
Low use cost and maintenance frequency. The molten aluminum heating and holding system is removed, reducing consumption. Launders are adopted for degassing, reducing the residual amount of molten aluminum and the loss of metal;low maintenance cost, convenient and fast replacement of launders.
Easy to install. Small size and low weight, space-saving; needless to install the required structure or foundation; installed in the joint positions of launders; a short period of time is required for on-site commissioning, saving production downtime.
Convenient for alloy conversion. There is no heating device or deep box, so at the end of per casting, most of the degassed metal is made into a product, which can easily clear away residual aluminum liquid in the degassing tank and convenient for the rapid alloy Conversion.
Easy to operate. No special starting procedure; a simple molten aluminum drainage device; convenient slag removal and simple working conditions.
Especially suitable for semi-continuous casting lines for the production of cast rods and renewable aluminum ingots. This casting technology is featured by frequent replacement of alloys without a very high dehydrogenation level.
The maximum temperature of molten aluminum is 750℃, while the launder shell surface temperature is required to be ≤60℃ and the launder lining life is required to be ≥12 months.
The rotor speed falls between 100-600rpm and the inert gases used are high-purity N2 and high-purity Ar. The degassing efficiency demands that when it is not greater than the maximum flow rate, the inlet hydrogen content is ≤0.30ml/100gAl, and when the aluminum liquid is 700-740℃, the hydrogen content after degassing is ≤0.22ml/100g. Furthermore, when hydrogen content at the inlet >0.30ml/100g-Al, the degassing efficiency should be ≥35%.
The power supply is 380V AC 50Hz, with a maximum of 10KVA.
HYDEB HDR-2 Heat Treatment Furnace is a Rotary Molten Aluminum Liquid Degasser Machine, which is designed to degas molten aluminum liquid without residual molten aluminum. This advanced machine has a rotor system that can rotate at a speed of 100-600rpm. It also has a launder out shell surface temperature that is ≤60℃ and launder lining life of ≥18 Months. Moreover, it has a degassing efficiency of ≥40% and can operate with high-purity nitrogen or argon as the inert gas.
The performance of HYDEB HDR-2 Heat Treatment Furnace is highly reliable, allowing for effective degassing of molten aluminum liquid with no residual. It can also degas rapidly and effectively, ensuring no secondary oxidation of the molten aluminum liquid. As a result, the machine is perfect for applications such as aluminum alloy production and die casting.
