Aluminum alloy refining process is an important step in aluminum alloy casting. Flux refining is usually used in the furnace. According to the crucible smelting and the weight of the charge, the charge, alloy ingot, intermediate alloy, and pure metal are added to the crucible one after another or at the same time and heated […]

Impurity elements refining in molten aluminum is removing iron and other impurity elements. Iron is the main impurity element in aluminum alloy. In the 6063 alloy, the national standard stipulates that it is not more than 0.35. If first-class industrial aluminum ingots are used in production, the iron content can generally be controlled below 0.25. […]

Aluminium Degassing Process: In addition to hydrogen, it is necessary to prevent moisture and various dirt from entering the crucible or furnace, but also to eliminate oxide inclusions and hydrogen in the aluminum liquid. Because only by effectively removing the dispersed inclusions suspended in the molten aluminum, can the molten aluminum be prevented from increasing […]

Refining agent degassing is currently the most commonly used method in aluminum plants to eliminate pinholes in aluminum alloy castings. In order not to cause a large amount of splashing of the aluminum liquid, the degassing agent can be added in batches, and the degassing ends the slag removal. When aluminum alloy is smelted, it […]

Rotary Degassing Aluminum works by rotating nozzle of degassing unit. The rotating nozzle has a rotating shaft, a rotor with blades (connected to the rotating shaft), and a stator with blades. Their interaction can provide the desired bubble shape for the melt. The refined gas emerges into the aluminum melt through the small gap between […]

Online purification equipment is an advanced melt purification method. The aluminum melt of primary aluminum, scrap, and remelted waste must be purified before being cast into ingots, slabs or rods. This can be accomplished by blowing non-chemically reactive gases such as nitrogen or argon into the aluminum melt. In most cases, a halogen gas is […]

When using a ceramic foam filter, the pore size of Ceramic Foam Filter Uses should be determined according to the quality requirements of the casting and the number of inclusions in the molten metal; the size of the filter should be determined according to the pouring speed and pouring weight. In order to ensure the […]

Ceramic foam filter for aluminum can be used in various casting alloys, and the product has been commercialized. This kind of filtration process has been widely promoted in industrially developed countries, and it has become the simplest and most effective method to improve the mechanical properties of castings and reduce pores and inclusions. The following […]

AdTech is a professional in ceramic foam filter manufacturers. The ceramic foam filter is made of continuous reticulated foam plastic as the framework, which is dipped in mud and then roasted at high temperatures. Therefore, the raw materials for making the filter plate are divided into foam and mud. The foam used in the production […]

Selection and Use Ceramic Foam Filter is important. In addition to considering the actual production requirements for the quality of aluminum products, the flow rate of aluminum in the launder, the total amount of filtration, the cleanliness of the aluminum itself, and the production cost should also be considered. Choosing a ceramic foam filter plate […]
