Covering agent RH-FG
Aluminum melt in a molten state is easily oxidized and aspirated due to its non protective oxide film. To this end, a flux powder with a slightly lower melting point than aluminum, a lighter specific gravity than aluminum melt, good flowability, and the ability to quickly form a dense and uniform protective film on the surface of aluminum melt is selected to be sprinkled on the aluminum melt. This is the basic requirement for the covering agent
Technical parameters
Model: RH-FG
Shape: White powder, particle size<20 mesh, with water content below 0.5%
● Scope of use, except for high magnesium alloys, other aluminum and aluminum alloys.
Reference dosage: Calculate and weigh the unit dosage of 0.8-0.1Kg/m2 for the area of aluminum melt, and increase or decrease it according to the purity of the melt and the humidity in the air. Melting point:<660 ° C
◆ Usage
When impure materials and non-metallic inclusions are cleaned out by the covering agent, the morphology or paste or liquid state of the surface slag will vary depending on the amount of covering agent added. To maintain the complete coverage of the liquid level, it is necessary to add a covering agent multiple times, preferably at the beginning of the metal melting. After all the metal has melted, the covering agent should be sprinkled to protect the melt during the insulation and standing process
◆ Main advantages
Containing an appropriate amount of cryolite, it has the effect of adsorbing and slagging, especially when a liquid covering layer is formed on the surface of the aluminum liquid, and then adding back to the furnace, head and tail materials or debris materials, it has the cleaning function and can slag and melt some of the aluminum oxide in the slag, separating the aluminum liquid from the furnace gas, thereby reducing burning loss and oxidation suction.
◆ Packaging and storage
Corrugated cardboard box packaging: Each box weighs 20-25 kilograms and should be properly stored, taking care to prevent moisture.
