At present, using N2 and Ar gas as a carrier, adding a small amount of pollution-free refining agent, using a single tube, porous or rotary……
The purification technology of aluminium, which is based on hydrogen removal, mainly includes bubble floatation, vacuum treatment, ultrasonic treatment, and rare earth hydrogen storage. Because……
The process of removing hydrogen from molten aluminum first takes place inside the melt. The hydrogen atoms dissolved in molten aluminum undergo migration to the……
The degassing equipment for molten aluminum rotates the ejector immersed in the melt so that the scavenging gas (usually an inert gas) is distributed in……
When the thickness of the cast-rolled sheet is thicker, due to the certain temperature difference between the upper and lower surfaces of the melt in……
The filter box has a variety of styles, including single-chamber and double-chamber; filters include vertical single-plug, double-plug, multi-plug, horizontal type with heating and insulation, and……
Preparation before the casting process The working surface of the crystallizer is smooth, and the inner surface is polished with sandpaper when using ordinary molds.……
The slag mixed into the ingot or other non-metallic impurities falling into the ingot are called non-metallic inclusions. The fracture features are black strips or……
The cast-rolled strip contains slag, flux, various refractory fragments, metal oxides and other impurities, which are called inclusions. There are many kinds of inclusions in……
