Compound purification mainly refers to a new purification method that uses two or more purification technologies at the same time and complements the advantages of various technologies to significantly improve the purification effect and efficiency of aluminum melt. At present, composite purification mainly includes online degassing and filtration purification. The degassing and filtration composite purification […]

The ceramic foam molten Alu filters can effectively filter out the inclusions in the aluminum melt and the hydrogen adsorbed on the surface of the inclusions. The material of the filter mainly includes corundum microporous ceramic tube, glass fiber mesh and foam ceramics. The corundum microporous ceramic tube can filter out the oxide inclusions of […]

The online purification technology of aluminum alloy melt mainly refers to the refining of the aluminum alloy melt out of the furnace. The traditional furnace treatment method has been gradually replaced by continuous purification outside the furnace. The online purification technology of aluminum alloy melt has a good and stable effect, can obtain a better […]

The hydrogen removal purification can generally be described as a bubble floatation method. Through a certain method, a large number of bubbles are created in the aluminum liquid, and the partial pressure difference between the hydrogen in the aluminum liquid and the bubbles is used to make the hydrogen in the aluminum liquid continuously enter […]

The purification treatment of aluminum alloy melt is one of the basic guarantee measures for the production of high-quality aluminum castings, and it is also the main means to improve the comprehensive performance of aluminum alloys. The refining effect of aluminum alloy melt has an important influence on the formation of porosity, pores and inclusions, […]

CFF filtration purification is to remove the large inclusions and some suspended fine inclusions carried in the molten aluminum through the filter medium, reduce the gas content in the molten aluminum and remove some harmful elements in the molten aluminum, and change the physical properties and solidification characteristics of the molten aluminum. CFF filtration purification […]

During the casting process, the burning loss of molten aluminum is inevitable, but the resulting loss of metallic aluminum cannot be ignored. How to reduce the burning loss of molten metal becomes the key. It is necessary to strictly control the temperature of the molten aluminum, reduce the disturbance of the molten aluminum by improving […]

A large amount of aluminum liquid is sucked into the vacuum ladle from the electrolytic cell and transported to the foundry shop to be injected into the mixing furnace. After the aluminum liquid is mixed and stirred, slagging and degassing, and chemical composition inspection, it is cast into aluminum ingots or rolled. Aluminum plates, round […]

After placing the ceramic foam filter in the filter system, the filter produces a comprehensive resistance to the liquid casting alloy. This resistance mainly includes: Thermal resistance: The resistance caused by the temperature difference between the high-temperature molten metal and the filter. Force resistance: At the entrance of the filter, a large stream of molten […]

The use of ceramic foam filter plates to remove impurities in the aluminum melt is currently a method widely used by aluminum processing manufacturers. It has the characteristics of strong adaptability, low price, safe and simple operation, and remarkable effect. However, there are many aspects of the filter plate that need to be paid attention […]
