Box type in-line rotor degassing unit (BDU)

 

• Dehydrogenation/impurity removal/dealkalization!
• One of the most effective molten aluminum degassing technologies, the first choice for high-end aluminum castings!

 

Equipment Introduction
• The BDU 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.
• The BDU offers more advantages than the commercially available mainstream box-type degassers. For example, multiple key technologies, such as box tightness and anti-turbulent flow on molten aluminum surface, have been improved, ensuring the high-efficiency, continuously stable and low-cost operation of the degassing unit .

Launder type in-line rotor degassing unit (LDU)

 

• Easy to use, efficient, flexible, low-cost

 

Equipment Introduction
• 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.

Equipment Features
• The degassing efficiency is high, above 40%. Continuous degassing in multiple sub-zones increases the area and time of contact between bubbles and molten aluminum; seal design is adopted. During the whole casting process, there is an inert headspace maintained on the surface of molten aluminum to avoid the generation of more slags and prevent secondary pollution to improve the degassing efficiency.
• Low use cost and maintenance cost. The molten aluminum heating and heat preservation system is removed, reducing consumption; launders are adopted for degassing, reducing the residual amount of molten aluminum and the loss of metal; it’s easy to replace 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 after the end of each casting, most of the degassed metal is made into products with the residual molten aluminum in the degassing launders cleared away, facilitating alloy conversion.
• Easy to use. 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.

CFF Filtration Box (CFB)

 

• The most widely used high-efficiency filtration system


Equipment Introduction
- The CFB is widely used for molten aluminum filtration in the aluminum casting process to prevent the particulate impurities in molten aluminum from entering the casting blank and affecting the quality of aluminum products.
- A satisfactory filtration effect can be achieved if a right type of filtration box and correct specifications of the CFF filtration board are selected in accordance with the quality requirements of casting products, the flow rate of molten aluminum, the total filtration amount of molten aluminum and the purity of molten aluminum.

Filtration Box Features
• Significant filtration effects. It meets the production requirements of ordinary products and even the stringent production requirements of aluminum alloy can materials, aero-metals and other relevant materials. The filtration box can effectively filter out bulk inclusions in the molten aluminum, adsorb small inclusions in the molten aluminum, refine the crystalline structure of castings, reduce the content of hydrogen in the molten aluminum and lower the content of harmful elements such as Na and K in the molten aluminum by adsorption.
• The filtering method is easy to use. Standardized and serialized production of the CFF filtration boards has been realized. Different filtration effects can be achieved if filtration boards with different pore sizes (20-60ppi) are combined together in use according to the quality and flow requirements of molten aluminum.
• Economical. The filtration board has high strength and resistance to abrasion by molten aluminum, good thermal shock resistance and a long service life; the heating cover ensures that one filtration board can be reused more than 6 times in the filtrate, thereby reducing the cost of consumables; the lining of the filtration box, similar to that of the degassing box, has high aluminum tolerance, heat preservation and resistance to thermal and cold shocks, and has a longer service life.
• Easy to install and maintain. The preformed lining of the filtration box is easy to replace, minimizing production downtime.

Introduction
- The launder is of vital importance for the quality and energy-saving effect of molten aluminum metallurgy. Made of high-quality medium-density melted quartz refractory H2000 and pre-sintered at 800°C before assembly, the lining of HYDEB launder has high aluminum tolerance, low thermal conductivity, low shrinkage and high strength. The launder cover can be used to reduce heat loss by over 50% while a launder heating unit can be mounted to minimize the temperature drop of the launder, thus reducing the tapping temperature of molten aluminum and protecting some highly burnable alloying elements.
- There are a number of launder shapes, such as DC slot, elbow, tee joint and cross fitting. They can be combined flexibly together in use according to different site conditions.
