The mechanism of adsorption purification method is that the aluminum alloy melt is in direct contact with N2, Cl2 and other gases, adsorbents and refining agents and other media, so that the gases and solid oxide inclusions will interact with these media, so as to remove the gas and inclusions in the melt. The adsorption […]

In order to provide large-size, high-quality and high-quality blanks for the production of high-precision aluminum strips for aluminum processing enterprises, the electrolytic aluminum plant adopts the fully automatic low-level (LHC) combined mold casting technology and uses the electrolytic raw aluminum liquid to directly batch for hot rolling. Aluminum alloy slab ingots can cast 2~5 slabs […]

The electrolytic aluminum liquid directly produces cast-rolled coils, although it can save costs and reduce consumption. However, compared with remelted aluminum ingots, the excessively high proportion of electrolytic aluminum liquid will directly lead to problems such as high hydrogen content, high slag content, high alkali metal content, and coarse grain size of cast-rolled slabs. Therefore, […]

Due to the relatively high content of alkali metals in the electrolytic aluminum liquid, the refining process needs to be strengthened. Electrolytic Aluminum Refining Process Use 5%~10% concentration of chlorine and argon to refine the furnace for no less than 15 minutes, or use high-quality refining agents for multiple refining. After the flux refining is […]

Above the water-cooled crystallizer, install a heat-preserving cap made of insulating film material, also called hot top cap, pouring cup. The requirements for the hot top cap are no chemical reaction with molten aluminum, no moisture absorption, no oil absorption, no wetting to molten aluminum, high-temperature resistance, good insulation performance, thermal shock resistance, good strength, […]

The rotating rotor degassing method can give full play to the hydrogen removal advantages of the bubble floatation method. The key is that the liquid forms turbulent flow under the strong action of the rotor, and the bubbles are broken and uniformly dispersed under the action of the rotor and the turbulent flow. The rotating […]

The aluminium flux purification of molten aluminum is one of the measures to ensure high-quality aluminum alloy products, and it is also the main means to improve the overall quality of aluminum alloys. The refining effect of molten aluminum has an important influence on the formation of pores, shrinkage cavities and inclusions, and directly affects […]

Foam ceramic plate filtering is the last process in the purification treatment of aluminum melt. It is particularly important to choose the second generation of foam ceramic filter plates. It needs to be particularly pointed out that the secondary pollution of the melt that may occur after the aluminum melt leaves the filter box to […]

Choosing the best ceramic foam filter plate is an important task, and the size of the filter plate depends on the flow rate and total amount of the filtered metal. Semi-continuous casting mainly considers the flow of metal, while continuous casting mainly considers the total amount of metal. The size of the ceramic foam filter […]

Metal melt purification is a key technology to ensure the metallurgical quality of aluminum alloy materials. The aluminum casting process is smelting → standing → online Al-Ti-B refinement → online degassing → foam ceramic sheet filtration → casting. Casting is the pre-process of hot rolling, and the quality of the billet directly affects the quality […]
