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 […]

With the rapid development of automobile lightweight technology, the steering action of aluminum wheels is required to be more precise. In order to prevent the tilt of the tires when turning, the performance requirements of aluminum wheels are higher, so the requirements for the internal metallurgical quality are even higher. It is extremely important to […]

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 […]
