Degassing process in aluminum can be divided into two situations: one is the hydrogen removal process that can form hydrogen bubbles; the other is the hydrogen removal process that cannot form hydrogen bubbles. The degassing process in aluminum that can form hydrogen bubbles can be roughly divided into three stages: first, the formation of bubbles, […]

Rotary degassing purification method is a kind of bubble floatation method, and it is also the most widely used aluminum alloy melt purification method. Rotary blowing degassing purification method by degassing unit is to pass inert gas in aluminum alloy melt in the aluminum alloy melt. It is broken and ejected at high speed when […]

Porous ceramic filters filtration efficiency mainly has filtration accuracy, which refers to the particle size of the smallest solid impurity particles in the fluid medium. For ceramic filters, the filtration accuracy can reach 0.1Lm. The main factor that affects the porous ceramic filters filtration efficiency is the maximum pore diameter of porous ceramic filter elements. […]

Porous ceramics are a kind of microporous filter media. In the general sense, porous ceramics are ceramic filter materials made of refractory raw materials as aggregates and combined with binders that have been sintered at high temperatures. The structure has a large number of penetrations. The fine pores with controllable pore size. Compared with other […]

Rotary degassing purification method has become a recognized high-efficiency hydrogen removal technology for aluminum alloy melt at home and abroad, and is favored by more users. The method of spraying gas flux with rotating nozzles has become an important development trend of drilling alloy melt purification technology at home and abroad. In recent years, due […]

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 […]
