20 8月 Constellium Japan Ceramic Foam Filter
Constellium Japan Ceramic Foam Filter can effectively remove large inclusions in molten aluminum, absorb micron-level fine inclusion particles, improve surface quality, improve product performance, improve microstructure, and increase yield. It is widely used in the production of aluminum profiles, aluminum foils, and aluminum alloys.
Pore size of ceramic foam filter (PPI): 10/20/30/40/50/60
The 30ppi cast filter is the most commonly used ceramic foam filter in the aluminum casting industry.
Ordinary aluminum castings usually use 10-40ppi ceramic filter plates.
Aviation and high-quality aluminum materials usually use 30-60ppi ceramic filter plates.
The purpose of waste aluminum pretreatment technology is to realize the mechanization and automation of waste aluminum separation, maximize the removal of metal and non-metal impurities, and effectively separate waste aluminum.
The most ideal method for sorting scrap aluminum is to divide the scrap aluminum into several categories according to the main alloy components, such as alloy aluminum, aluminum-magnesium alloy, aluminum-copper alloy, aluminum-zinc alloy, aluminum-silicon alloy and so on.
This can reduce the difficulty of removing impurities and adjusting the composition in the smelting process, and can comprehensively utilize the alloy components in the scrap aluminum, especially the scrap aluminum containing high zinc, copper, and magnesium, which should be stored separately and can be adjusted to a smelted aluminum alloy. Ingredients of raw materials.
Constellium Japan Ceramic Foam Filter is one of the most widely used industries. Its function is to make the turbulent and agitated metal liquid pass through the foam ceramic honeycomb pores to become a stable, uniform and clean metal liquid.
Thereby, the rejection rate of castings caused by casting defects such as non-metallic inclusions is greatly reduced, and the production cost is saved.
Cff aluminum uses polyurethane foam as a carrier and is immersed in a ceramic slurry made of ceramic powder, binder, sintering aid, suspending agent, etc.
Then, the excess slurry is extruded, so that the ceramic slurry is evenly coated on the carrier skeleton to form a green body.
The green body is dried and sintered at high temperature. This process is also called organic foam impregnation method, which is a common foam ceramic production process in China.
Alumina ceramic foam filter is an important branch of the three major types of ceramic foam (alumina, silicon carbide, and zirconia), and it is also the earliest type of ceramic foam. It is widely used in aluminum and alloy casting industry.
At present, with the continuous improvement of the performance requirements of aluminum and aluminum alloy products, new requirements are continuously put forward for the filtration of aluminum liquid. This requires casting characteristics such as high purity of the aluminum liquid, less floating balls, and stable flow rate of the aluminum liquid to achieve better aluminum products. Good physical and chemical properties and mechanical processing properties to meet more stringent conditions of use, to achieve the purpose of extending the service life of aluminum products.
Every process in the production of foam ceramics has an impact on the quality of foam ceramics. Among them, the key process components, sponge processing and sintering have the greatest impact on product quality. The spraying process mainly affects the product quality and appearance, but also has a certain impact on the internal quality.
