Purification treatment of aluminum alloy melt is one of the basic measures to produce high quality aluminum castings, and it is also the main means to improve the comprehensive properties of aluminum alloy. The refining effect of aluminum alloy melt has an important influence on the formation of porosity and inclusion, and directly affects the […]

When casting with the new hot top casting equipment, the high temperature melt in the distributing launder directly rushes to the center of the liquid cavity of the ingot, thus forming a deep and sharp liquid cavity. There is a large tensile stress at the bottom of the liquid cavity, which is easy to cause […]

Ceramic foam can be divided into two categories, namely, open hole (net) ceramic material and closed-cell ceramic material, depending on whether each hole has a solid wall. If the foam solid is only included in the hole, it is called an open hole ceramic material whose pores are interconnected. If there is a wall surface, […]

Aluminium is melted in a melting furnace before further processing and almost always filtration is required. The ceramic foam filter filtration method depends on the casting technique used or the treatment of the molten aluminum. It is generally believed that it is possible and beneficial only when sufficient amounts of metal are used. However, filters […]

Magnesium is also a common impurity in the production of secondary aluminum. The following Mg removal methods are usually used to remove magnesium in the waste aluminum melt. Mg Removal Methods Magnesium removal by oxidation Magnesium removal by oxidation is based on the principle that the affinity of magnesium and oxygen is greater than that […]

Filtering method for molten aluminum is based on the principle that the iron-rich phase impurities in the aluminum alloy melt are segregated at a lower temperature and a longer holding time, and mechanical filtration is used to remove the aggregated iron-rich phase materials. The filtering iron removal method is generally carried out during the melt […]

Degassing technology is one of the main components of quality assurance in foundry industry. The quality of cast material depends largely on the number of defects. One of the main defects in near net shape casting is porosity. When melting aluminum scrap, the process of Degassing Technology is very important to produce high quality aluminum […]

Aluminum Liquid Purification is important, because the electrolytic aluminum solution contains a large number of non-metallic inclusions and carbides, nitrides, and sulfides. When the electrolytic aluminum liquid directly enters the melting pool of the smelting furnace, it is easy to adhere to the refractory lining of the smelting furnace, and is closely integrated with the […]

Molten Aluminum Casting process is to add a certain proportion of electrolytic aluminum liquid and solid charge (remelted aluminum ingots, process waste, and various aluminum-based master alloys) to the melting furnace for smelting. While the electrolytic aluminum liquid is transferred into the melting furnace, various non-metallic inclusions and a large amount of alkali metals in […]
