Online Metal Degassing Systems can effectively remove the hydrogen content in aluminum alloy, and can ensure that the cast-rolled billet used to produce ultra-thin aluminum foil meets the quality requirements. The quality of the purified cast-rolled billet of the aluminum melt determines whether the 0.005mm aluminum foil can be rolled and the number of pinholes […]
The presence of gas (usually hydrogen) and other particles in gravity or sand castings can cause bubbles, which can severely impair the appearance and performance (overall strength and density) of the finished product. This makes effective metal degassing critical to the quality of the casting process. Traditionally, graphite is the most widely used material for […]
Methods Of Degassing In Foundry main include flux refining and degassing with inert gas. Inert gas is continuously blown into the melt, and the refining method in which the oxidized inclusions and hydrogen are brought to the liquid surface during the floating of the bubbles is called inert gas refining. The reason why blowing inert […]
Nitrogen degassing aluminium is used for gas blowing refining, it has the characteristics of convenient operation, environmental protection and safety, and low cost, but the refining effect is restricted by the purity of the inert gas itself. Generally, inert gases will always contain a certain amount of moisture and oxygen even if strict purification measures […]
Degassing with Nitrogen has been gradually eliminated in the modern aluminum industry, fluxes are generally used together with nitrogen. Use active gas chlorine as a purifying agent (chlorination method). In the chlorination method, when the chlorine gas is passed into the aluminum liquid, a lot of abnormally small bubbles are generated, which are fully mixed […]
Aluminum degassing system adopts a dual-rotor gas refining device, which refining gas is blown through the rotating nozzle to generate tiny bubbles. The rotating nozzle is made of graphite. The nozzle structure design takes into account the uniform ejection of bubbles. The rotating impeller is also used to break the bubbles, increase the contact area […]
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 […]
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 […]
Rotary degassing device is suitable for gas removal treatment between furnace and casting position. Through the vertical hollow shaft and the rotor at the lower end of the shaft, the inert gas is blown into the melt, and it is distributed as tiny bubbles. Through the rotation of the impeller, the fine bubbles and the […]
