مع التطور السريع لتكنولوجيا تخفيف وزن السيارات، أصبح من الضروري أن تكون حركة التوجيه للعجلات المصنوعة من الألومنيوم أكثر دقة. ومن أجل منع انحراف الإطارات عند الانعطاف، أصبحت متطلبات الأداء الخاصة بالعجلات المصنوعة من الألومنيوم أعلى، وبالتالي فإن متطلبات الجودة المعدنية الداخلية أصبحت أعلى أيضًا. ومن المهم للغاية أن […]

In the entire production process of using electrolytic raw aluminum liquid as a raw material to produce round aluminum rods, the purification of aluminum melt has become a key factor in the production process, which is determined by the characteristics of electrolytic raw aluminum liquid and the requirements of round aluminum rods. It is decided […]

Inert gas rotary injection was first applied to continuous aluminum liquid refining in large melting furnaces. Each rotating nozzle is composed of a graphite rotating rod and graphite blades, and the inert gas is passed into the liquid through a specially designed rotating rod and blades. The rotation of the nozzle and the shearing action […]

Casting A356 aluminum alloy has been widely used in products such as automobiles and motorcycles due to its excellent casting properties, heat treatment properties, processing properties and mechanical properties, and has become one of the most important AI-Si series cast aluminum alloys. The main defects of cast aluminum alloy-pores and slag inclusions are caused by […]

Melt purification and modification treatment methods can significantly affect the properties of the alloy, especially the toughness and electrical conductivity. Research and develop various advanced melt purification and modification treatment technologies, focusing on solving the problem of low ingot metallurgical quality. With the development of the automobile industry, more and more aluminum alloy castings are […]

Online rotary degassing is necessary for all molten metal production. At the aluminum melting temperature (700°C and above), water vapor decomposes into hydrogen and oxygen. Oxygen reacts with the aluminum liquid to form alumina, and the hydrogen (H) decomposes into hydrogen atoms (H) and dissolves into the aluminum liquid. Therefore, it is inevitable to dissolve […]

Aluminum alloy degassing purification is a basic step in the production of aluminum alloy. It can reduce the hydrogen melted in the solid metal, improve the purity of the metal by reducing impurities, and reduce the alkali metal content in the final alloy to obtain purer aluminum liquid. Aluminum Alloy Degassing Purification are achieved by […]

Rotary degassing method is currently the most widely used method of degassing and purifying molten aluminum. AdTech online degassing unit adopts this degassing method for molten aluminum purification. The principle of the rotary degassing method is to pass inert gas or active gas insoluble in the molten aluminum into the molten aluminum, or add chlorine […]

The high-throughput continuous casting and rolling aluminum alloy production process use electrolytic aluminum liquid to directly equip the alloy solution. Then it passes through a double-strip continuous casting machine and a hot triple-rolling mill. It can be directly formed into blanks of 2mm-8mm, and the flow volume of the melt can reach 50th. However, there […]

In terms of secondary aluminum smelting technology, the commonly used degassing method is to spray gas into the aluminum alloy liquid, and use the principle of partial pressure to diffuse the hydrogen in the alloy liquid to the bubbles to achieve the purpose of degassing. In addition to spray guns, porous refractory bricks, and rotating […]
